FUNCTION: Sets up an arbitrary active work plane &lt;br /&gt;
&lt;br /&gt;
TO SET UP AN ARBITRARY WORK PLANE:&lt;br /&gt;
&lt;br /&gt;
#Activate the '''Work Plane Tool''' to enable CubeCAD's &amp;amp;quot;Work Plane Mode&amp;amp;quot;. &lt;br /&gt;
#The Work Plane dialog opens up at the lower right corner of the screen.&lt;br /&gt;
#Use one of the following three methods to establish a new work plane.&lt;br /&gt;
#Hover the mouse over any object in the project workspace to highlight one of its faces. Click on the selected face snap point, &amp;lt;i&amp;gt;i.e.&amp;lt;/i&amp;gt; the center of a highlighted planar face. A new work plane appears overlaid on the selected face.&lt;br /&gt;
#Or while you are moving the mouse in one of the three principal XY, YZ or ZX work planes, click any blank point and drag the mouse. A semi-translucent plane perpendicular to the current principal work plane is drawn and displayed in the project workspace. The normal plane follows the movement of the mouse as you drag it. Once you reach the desired orientation, press the keyboard's' {{key|Enter}} key to finalize the new work plane.&lt;br /&gt;
#Or click successively on any three distinct points in the project workspace (including other objects' snap points). A new work plane is established that passes through the three selected points.&lt;br /&gt;
&lt;br /&gt;
In all the three cases above, a translucent plane appears showing the location and orientation of the new work plane. The transverse axes (local X and Y axes) of the new work plane are displayed in red and green colors, respectively. A new &amp;amp;quot;User Coordinate System (UCS)&amp;amp;quot; is established on the new work plane. In the work plane dialog, you can see the world coordinates of the center of the UCS and its rotation angles with respect to the project's world coordinate system (WCS). From this dialog, you can change both the center coordinates and the rotation angles of the new work plane. Note that the visible size of the work plane is purely for visualization purposes; otherwise, the work plane has infinite extents. You can also change the '''Color''' and '''Transparency''' level of the work plane.&lt;br /&gt;

FUNCTION: Modifies the type and settings of the project workspace's grid&lt;br /&gt;
&lt;br /&gt;
NOTES, SPECIAL CASES OR EXCEPTIONS: [[EM.Cube]] offers two different types of grid: Adaptive and fixed. Note that the grid is hidden by default and can be displayed from the preferences dialog. The adaptive grid is the default choice, and its grid cell size changes dynamically according the viewport size. As a result of this, during a dynamic zoom process, the grid seems to maintain almost the same size even though your physical structure looks bigger or smaller depending on whether you zoom in or zoom out. The fixed grid, on the other hand, always maintains fixed dimensions and a fixed grid cell size. Therefore, the fixed grid grows or shrinks along with your physical structure due to a dynamic zoom operation. With a fixed grid, you can set different grid cell dimensions along the three principal axes.     &lt;br /&gt;

==Analog-to-Digital Converter (ADC) Bridge==&lt;br /&gt;
[[File:GK42.png]]&lt;br /&gt;
&lt;br /&gt;
The ADC Bridge takes an analog value from an analog node and may be in the form of a voltage or current.&lt;br /&gt;
If the input is less than or equal to &amp;amp;quot;in_low&amp;amp;quot;, then a digital &amp;amp;quot;0&amp;amp;quot; is generated. If&lt;br /&gt;
the input is greater than or equal to &amp;amp;quot;in_high&amp;amp;quot;, a digital &amp;amp;quot;1&amp;amp;quot; is generated. Otherwise,&lt;br /&gt;
a digital &amp;amp;quot;UNKNOWN&amp;amp;quot; is the output value. Unlike the DAC Bridge, ramping or delay is not applicable.&lt;br /&gt;
Rather, the continuous ramping of the input provides for any associated delays in the digitized signal.&lt;br /&gt;
&lt;br /&gt;
This model also posts an input load value based on the parameter input_load.&lt;br /&gt;

Area factor scales the model parameters RE and RC.  IC VBE is the initial voltage from base emitter. IC VCE is the initial voltage from collector to emitter.  TEMP is the overriding temperature. These parameters are based on the Gummel and Poon integral-charge model.  If these parameters are not specified, then it will reduce to the simpler Ebers-Moll model. &lt;br /&gt;
&lt;br /&gt;
The process model is mandatory for the BJT.  Descriptions of the process model parameters are given in the following table:&lt;br /&gt;

==Capacitance Meter==&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Capacitance Meter measures the total capacitance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total capacitance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense a capacitance value and alter their behavior based upon it.&lt;br /&gt;

==Capacitor==&lt;br /&gt;
[[File:GK120.png]]&lt;br /&gt;
&lt;br /&gt;
Capacitors are used to store electrical energy.  They can filter or remove AC signals or block DC current without disrupting AC signals. A capacitor's ability to store energy is termed capacitance and is measured in Farads, with values from pF to mF. The only time current flows through a capacitor is when the charge is collected on, or is removed from, its parallel plates. This means that the voltage across the capacitor is changing, which doesn't conform to DC analysis. In a physical circuit, there is a transition stage during which capacitors charge up to their final values. The result is the same as if these capacitors did not exist and the connections to them were left dangling. In other words, in a (steady-state) DC analysis, a capacitor behaves like an open circuit. Therefore, it is important that no section of the circuit is isolated from the capacitors. Every circuit node needs some path for DC current to the ground.&lt;br /&gt;
&lt;br /&gt;
A capacitor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
i(t) = C * (dv(t)/dt)&lt;br /&gt;
&lt;br /&gt;
Its initial voltage is only important when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked.&lt;br /&gt;
&lt;br /&gt;
An capacitor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
i = j ω * C * v &lt;br /&gt;
&lt;br /&gt;
All capacitor names must begin with C. &lt;br /&gt;

&lt;br /&gt;
[[RF.Spice A/D]] provides three types of capacitors: simple, user-defined (or real) and semiconductor. The standard capacitor parameters are N+, N-, VALUE, and IC. In a simple capacitor, VALUE must&lt;br /&gt;
be specified for the capacitance in Farads. IC is the (optional) initial condition for the capacitor voltage.&lt;br /&gt;

==Center-Tapped Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK97.png]]&lt;br /&gt;
&lt;br /&gt;
This five-pin three-port device models a center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;
&lt;br /&gt;

==Current Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17B.png]]&lt;br /&gt;
&lt;br /&gt;
Current source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a current source is its initial transient value.  For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset current. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==Current-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G20.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Current-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the turn-on and turn-off currents in Amperes and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the rest of [[parameters]]. When the current through the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the current through the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Darlington Pair==&lt;br /&gt;
&lt;br /&gt;
[[File:GK108.png]]&lt;br /&gt;
&lt;br /&gt;
A Darlington pair is a three-pin device that consists of two interconnected BJT transistors of the same type. The collectors of two transistors are connected together to provide the &amp;quot;Collector&amp;quot; pin of the pair. The base of the first BJT acts the &amp;quot;Base&amp;quot; pin of the pair. The emitter of the first BJT is internally connected to the base of the second BJT. The emitter of the second BJT acts as the &amp;quot;Emitter&amp;quot; pin of the pair. There are two types of Darlington pair: NPN and PNP. The parameterized generic Darlington pair also contains a diode connected between the collector and emitter pin as well as two base-emitter resistors, one across each BJT.     &lt;br /&gt;

==D Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G52.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type flip-flop is a one-bit, edge-triggered storage element which stores data whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). In addition, there are asynchronous set and reset signals, which are independent of the clock. When SET = RESET = 0, the data on the D line is transferred to the output Q on the rising edge of the clock. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

&lt;br /&gt;
The digital D-type latch is a one-bit, level-sensitive storage element which outputs the value on the data (D) line whenever the enable (EN) input line is 1 (high). The value on the data line is stored, i.e., held on the output (Q) line whenever the enable (EN) line is 0 (low). In addition, there are set and reset signals, which are independent of the enable line. When SET = RESET = 0, the data on the D line is transferred to the output Q whenever EN = 1. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

&lt;br /&gt;
This six-pin four-port device models a doubly center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;

The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;
&lt;br /&gt;
To change the value of H/B arrays, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

&lt;br /&gt;
[[File:GL24.png]]&lt;br /&gt;
&lt;br /&gt;
This is a voltage source with a single-tone frequency modulated waveform. The FM modulation index MDI is defined as the ratio of maximum frequency deviation to maximum signal amplitude. &lt;br /&gt;

==Frequency Meter==&lt;br /&gt;
[[File:G114.png]]&lt;br /&gt;
&lt;br /&gt;
The Frequency Meter is a four-pin shunt device that is connected in parallel with an AC source just like a voltmeter and measures the operating frequency of the AC circuit. The input pins are connected across the AC source. The voltage across the output pins is equal to the frequency of the source in Hertz within a scale factor SF. Note that the Frequency Meter is designed to work with a single-tone AC source of unit amplitude. If the amplitude of the source is not one, multiply the SF parameter by the non-unit source amplitude value. The output voltage of the Frequency Meter can be used in conjunction with linear or nonlinear dependent sources to model frequency-dependent quantities.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Model Identifier: fmeter&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Parameters:&lt;br /&gt;
&lt;br /&gt;
The only parameter is the scale factor SF with a default value of 1.0. Set SF = 1e-6 to read out the frequency in MHz. Set SF = 1e-9 to read out the frequency in GHz. Set SF = 6.283185 (2*pi) to read out the angular frequency &amp;amp;omega; in radian/s.  &lt;br /&gt;
&lt;br /&gt;
== Fuse ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK76.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 2-pin interactive current-controlled switch. If the current passing through the fuse is less than a specified threshold current, the switch is closed. If the current exceeds the threshold level, the fuse breaks and remains open thereafter. The device's symbol changes to display its state.   &lt;br /&gt;

==Ground==&lt;br /&gt;
&lt;br /&gt;
[[File:G15.png]]&lt;br /&gt;
&lt;br /&gt;
Ground has a voltage of zero (0) and is used as a reference to compute electrical values in the circuit. &lt;br /&gt;
All circuits &amp;lt;B&amp;gt;must&amp;lt;/B&amp;gt; be grounded to be properly simulated.  There is no limit on the number of grounds&lt;br /&gt;
you may use in a circuit.  All components connected to ground are referenced to a common point and treated&lt;br /&gt;
as linked through ground.&lt;br /&gt;
&lt;br /&gt;
==Hysteresis Block (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Hysteresis block is a simple buffer stage that provides hysteresis of the output with respect to the&lt;br /&gt;
input.  The in_low and in_high parameter values.  The output values are limited to out_lower_limit and&lt;br /&gt;
out_upper_limit.  The value of \93hyst\94 is added to the in_low and in_high points in order to specify the&lt;br /&gt;
points at which the slope of the hysteresis function would normally change abruptly as the input transitions&lt;br /&gt;
from a low to a high value.  Likewise, the value of \93hyst\94 is subtracted from the in_high and in_low values&lt;br /&gt;
in order to specify the points at which the slope of the hysteresis function would normally change abruptly&lt;br /&gt;
as the input transitions from a high to a low value.  In fact, the slope of the hysteresis function is&lt;br /&gt;
never allowed to change abruptly but is smoothly varied whenever the input_dowmain smoothing parameter&lt;br /&gt;
is set greater than zero.&lt;br /&gt;

[[File:XFMR4.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal center-tapped transformer with push-pull input is a five-pin three-port device with two primary input ports and one secondary output port. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P1}{v_S} = \frac{v_P2}{v_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; is the secondary voltage, v&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt; is measured between the top primary pin P1 and the center tap pin, and v&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom primary pin P2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.        &lt;br /&gt;

&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; is the primary voltage, v&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; is measured between the top secondary pin S1 and the center tap pin, and v&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom secondary pin S2. The red dots show the polarity of the windings on each side.

&lt;br /&gt;
The ideal transformer is a four-pin two-port device with the following relationship between the voltages and currents at its primary and secondary ports:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_S} = - \frac{i_S}{i_P} = \frac{N_P}{N_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; are the primary voltage, current and number of turns, respectively, and v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; are the secondary voltage, current and number of turns, respectively. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary turns ratio. Note that the ideal transformer model is defined based on controlled sources and does not involve any magnetic physical parameters as opposed to mutual inductors or ferrite core transformer.&lt;br /&gt;

==Inductance Meter==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductance Meter measures the total inductance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total inductance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense an inductance value and alter their behavior based upon it. Care must be exercised when connecting an Inductance Meter to the inductors of a circuit. This is due to the fact that inductors are treated by SPICE as current sources. This can cause a problem when an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. &lt;br /&gt;

==Inductive Coupler Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GK99.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductive Coupler Block couples any two existing inductors. This block doesn't have any pins because it doesn't actually represent inductors, only the coupling between them. This is useful if you want to&lt;br /&gt;
couple two inductors that are in different parts of the circuit, or if you want to couple more than two inductors together. In the latter case, use more than one of these, with each one coupling a pair of inductors.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are Inductor1, Inductor2, and k. Inductor1 is the name of first inductor, Inductor2 is the name of the second inductor, and k is the coefficient of coupling, 0 &amp;amp;lt; k &amp;amp;le; 1.&lt;br /&gt;
&lt;br /&gt;
==Inductive Coupling (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G41.png]]&lt;br /&gt;
&lt;br /&gt;
This function is a conceptual model which is used as a building block to create a wide variety of inductive and magnetic circuit models. This function is normally used in&lt;br /&gt;
conjunction with the “core” model, but it can also be used with resistors, hysteresis blocks, etc. to build up systems which mock the behavior of linear and nonlinear components.&lt;br /&gt;
The lcouple takes as an input (on the “l” port) a current. This current value is multiplied by the num_turns value, N, to produce an output value (a voltage value which appears on the&lt;br /&gt;
mmf_out port). The mmf_out acts similar to a magnetomotive force in a magnetic circuit;&lt;br /&gt;
when the lcouple is connected to the “core” model, or to some other resistive device, a current will flow. This current value (which is modulated by whatever the lcouple is&lt;br /&gt;
connected to) is then used by the lcouple to calculate a voltage “seen” at the “l” port. The voltage is a function of the derivative with respect to time of the current value seen at mmf_out.&lt;br /&gt;
&lt;br /&gt;
The most common use for lcouple will be as a building block in the construction of transformer models. To create a transformer with a single input and a single output, you&lt;br /&gt;
would require two lcouple models plus one “core” model. &lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
A1 (1 0) (2 3) lcouple1&lt;br /&gt;
&lt;br /&gt;
.model lcouple1 lcouple ( num_turns = 10 )&lt;br /&gt;

==Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK121.png]]&lt;br /&gt;
&lt;br /&gt;
Inductors are used to store magnetic energy. An inductor's ability to counteract current changes passing through it is called its inductance (L), which is&lt;br /&gt;
measured in Henrys. In a (steady-state) DC analysis, the inductor acts like a short circuit. It is indeed treated as a current source, which can be problematic if an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. The resistor may be of negligible value or one that accounts for the coil resistance of the inductor. In AC and transient analyses, the inductor develops a voltage across it in response to the changing magnetic&lt;br /&gt;
flux within its coil. &lt;br /&gt;
&lt;br /&gt;
An inductor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
v(t) = L*(di(t)/dt) &lt;br /&gt;
&lt;br /&gt;
The inductor's initial condition is optional. It is the initial value of the inductor current in Amperes that flows from node N+ through the inductor to node N-. The only time that the initial current matters is when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked. &lt;br /&gt;
&lt;br /&gt;
An inductor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
v = j &amp;amp;omega; * L * i&lt;br /&gt;
&lt;br /&gt;
All inductor names must begin with L.&lt;br /&gt;

==Inductor with Ferrite Core==&lt;br /&gt;
&lt;br /&gt;
[[File:GK94.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device models a physical inductor with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. Unlike the standard inductor device, you do not specify an inductance value for the inductor with ferrite core. Rather, you specify physical parameters like cross sectional area, core length and number of turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;

== Insulated Gate Bipolar Transistor (IGBT)==&lt;br /&gt;

[[File:GK111.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Insulated Gate Bipolar Transistor (IGBT) device with three pins: Collector(C), Gate (G), and Emitter (E). It is primarily used as a fast electronic switch. The IGBT combines the simple gate-drive characteristics of MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors. The device's model consists of an isolated gate FET for the control input, and a PNP bipolar power transistor as a switch. To further modify the internal device models, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.    &lt;br /&gt;

&lt;br /&gt;
This 3-pin device requires a voltage with an integer value on its second input pin. It produces a voltage equal to v&amp;lt;sub&amp;gt;in1&amp;lt;/sub&amp;gt; % v&amp;lt;sub&amp;gt;in2&amp;lt;/sub&amp;gt; and sends it to the output with a default unity gain.&lt;br /&gt;

==Integrator Block==&lt;br /&gt;
&lt;br /&gt;
[[File:G32.png]]&lt;br /&gt;
&lt;br /&gt;
The Integrator Gain and input offset parameters are also included to allow for tailoring of the required&lt;br /&gt;
signa.  Output upper and lower limits are also included to prevent convergence errors resulting from excessively&lt;br /&gt;
large output values.  Note that these limits specify integrator behavior similar to that found in an operational&lt;br /&gt;
amplifier-based integration stage, in that once a limit is reached, additional storage does not occur. &lt;br /&gt;
Thus the input of a negative value to an integrator which is currently driving at the out_upper_limit&lt;br /&gt;
level will immediately cause a drop in the output, regardless of how long the integrator was previously&lt;br /&gt;
summing positive inputs.  The incremental value of output below the output_upper_limit and above the output_lower_limit&lt;br /&gt;
at which smoothing begins is specified via the limit_range parameter.  In AC analysis, the value returned&lt;br /&gt;
is equal to the gain divided by the radian frequency of analysis.&lt;br /&gt;
&lt;br /&gt;
Note that truncation error checking is included in the \93int\94 block.  This should provide for a more accurate&lt;br /&gt;
simulation for the time integration function, since the model will inherently request smaller time increments&lt;br /&gt;
between simulation points if truncation errors would otherwise be excessive.&lt;br /&gt;

==Junction Field Effect Transistor (JFET)==&lt;br /&gt;
&lt;br /&gt;
[[File:G12.png]]&lt;br /&gt;
&lt;br /&gt;
The JFET is the simplest transistor device and has three pins: gate, drain and source. The JFET defaults are based on the Shichman and Hodges FET model. This is a square-law device because of the expression relating the drain current to the gate-to-source voltage: &lt;br /&gt;
Idrain=*(VGS-Vthreshold)2.  In real JFETs, near the saturation point, the drain currents vary with the drain voltages. This can be modeled by the following formula:  Idrain=*(VGS-VTO)2*(1+*VDS), which yields an increasing&lt;br /&gt;
drain current for increasing values of VDS.&lt;br /&gt;
&lt;br /&gt;
The gate-to-source and gate-to-drain junctions each have a nonlinear capacitor.  The zero-bias capacitance value is selected for each junction.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

The CCCS is a current source whose current is directly proportional to the current across a controlling Ammeter or a voltage source. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the current gain, which has a default value of one. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the current gain.   &lt;br /&gt;

The VCVS is a voltage source whose voltage is directly proportional to the voltage across a controlling voltmeter of the voltage between two circuit nodes. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling voltmeter or the two controlling nodes, as well as the voltage gain, which has a default value of one. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the voltage gain.  &lt;br /&gt;

==Lossless Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G21.png]]&lt;br /&gt;
&lt;br /&gt;
The lossless transmission line is a four-pin two-port device that models only one propagating mode of an ideal transmission line.  When using this SPICE model, should all four nodes of the actual circuit be distinct, two modes may be activated, and this device would be insufficient for that purpose. To circumvent this potential problem, two transmission line devices would be required. Due to the implementation details, you may produce more accurate simulation results with a lossy transmission line device with zero loss.&lt;br /&gt;
&lt;br /&gt;
Optional initial condition parameters are the voltage and current at each of the transmission line ports.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are Z0, TD, F, NL, IC, described below:&lt;br /&gt;

==Lossy Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G22.png]]&lt;br /&gt;
&lt;br /&gt;
The lossy transmission line is a four-pin two-port convolution model for uniform constant-parameter distributed lines. MNAME is the process model name, which&lt;br /&gt;
includes a set of pre-specified options as described below.&lt;br /&gt;
&lt;br /&gt;

The RLC (uniform transmission line with series loss only), RC (uniform RC line), LC (lossless transmission&lt;br /&gt;
line), and RG (distributed series resistance and parallel conductance only) lines have been implemented. &lt;br /&gt;
The length (LEN) must be given.  COMPACTREL and COMPACTABS control the compaction of past history values&lt;br /&gt;
used in convolution.  Larger values for these lower accuracy but improve speed.  These are used with the&lt;br /&gt;
TRYTOCOMPACT option. &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Magnetic Core (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G42.png]]&lt;br /&gt;
&lt;br /&gt;
This device is used as a building block to create a wide variety of inductive and magnetic circuit models. It is almost always to be used in conjunction with the &amp;quot;lcouple&amp;quot; model to build up systems which simulate the behavior of linear and nonlinear magnetic components. There are two fundamental modes of operation for the core model. These are the &amp;quot;PWL&amp;quot; mode (which is the default and most&lt;br /&gt;
likely to be of use to you) and the &amp;quot;Hysteresis&amp;quot; mode.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;PWL Mode (mode = 1)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the PWL mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf) value. This value is divided by the total effective length of the core to produce a value for the Magnetic Field Intensity, H, which is then used to find the corresponding Flux Density, B, using the piecewise linear relationship described by you in the H_array / B_array coordinate pairs. B is then multiplied by the cross-sectional area of the core to find the Flux value, which is output as a current. The pertinent mathematical equations are:&lt;br /&gt;
&lt;br /&gt;
H = mmf / L, where L = Length (in apmere-turns/meter)&lt;br /&gt;
&lt;br /&gt;
B = f(H)&lt;br /&gt;
&lt;br /&gt;
&amp;amp;Phi; = B * A, where A = Area&lt;br /&gt;
&lt;br /&gt;
The B value is derived from a piecewise linear transfer function described to the model by the H_array and B_array coordinate pairs.  This transfer function does not include hysteretic effects; for that, you would need to substitute a HYST model for the core. The magnetic flux value &amp;amp;Phi; in turn is used by the &amp;quot;lcouple&amp;quot;&lt;br /&gt;
code model to obtain a value for the voltage reflected back across its terminals to the driving electrical circuit.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Hysteresis Mode (mode = 2)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the Hysteresis mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf)&lt;br /&gt;
value.  This value is used as input to the equivalent of a hysteresis code model block.  The parameters&lt;br /&gt;
defining the input low and high values, the output low and high values, and the amount of hysteresis are&lt;br /&gt;
as in that model. The output from this mode, as in PWL mode, is a current value which is seen across the magnetic core port.&lt;br /&gt;
&lt;br /&gt;
One final note to be made about the two core models is that certain parameters are specific to one or the other.  In particular, the in_low, in_high, out_lower_limit, out_upper_limit, and hysteresis parameters are not available in PWL mode. Likewise, the H_array, B_array, area, ad length values are unavailable&lt;br /&gt;
in Hysteresis mode.  The input_domain and fraction parameters are common to both modes (though their behavior is somewhat different; for explanation of the input_domain and fraction values for the Hysteresis mode, please refer to the Hysteresis Block discussion.&lt;br /&gt;

==Marker==&lt;br /&gt;
&lt;br /&gt;
[[File:G16.png]]&lt;br /&gt;
&lt;br /&gt;
The marker serves several purposes:&lt;br /&gt;
&lt;br /&gt;
* It can appear as a default plot in simulations if the &amp;amp;quot;Voltage Probe&amp;amp;quot; box is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to set the initial voltage or voltage guess at the node it is connected to.&lt;br /&gt;
&lt;br /&gt;
* It can be used as a port for a subcircuit when you choose the checkbox labeled &amp;quot;Use as Subcircuit Port&amp;quot; is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to explicitly set a node number in place of the arbitrarily assigned node number by the program. In this case, make sure the &amp;amp;quot;Set Node Index&amp;amp;quot; box is checked.  Otherwise, it will act as just a voltage probe.&lt;br /&gt;
&lt;br /&gt;
* It can be used to connect different parts of a circuit in place of wires. To use markers as virtual connectors, place them at points where wires would otherwise connect. Then set the Part Title of the two (or more) markers to the same name, and they will act as a single circuit node.&lt;br /&gt;

==MESFET==&lt;br /&gt;
&lt;br /&gt;
[[File:G14.png]]&lt;br /&gt;
&lt;br /&gt;
The MESFET is a Schottky-barrier gate FET with six times greater electron mobility than silicon.  MESFETs are important devices for creating high frequency circuits. They function by creating a potential barrier between the gate and the channel when the metal gate&lt;br /&gt;
contacts the gallium-arsenide substrate. Electron velocity saturates for fields approximately ten times lower than with silicon.  The Curtice model includes linear and saturated operation.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

&lt;br /&gt;
The MOSFET is an active device that has up to 4 pins.  The three standard pins are gate, drain, and source.  These are given in the default symbol.  The bulk node, which is grounded by default, is the fourth pin.  The MOSFET with the bulk is named mos_n_lvl1_4 (the lvl1 is for level 1, the n for nmos, and the 4 for 4 pins.)&lt;br /&gt;
&lt;br /&gt;
The standard [[parameters]] are L, W, AD, AS, PD, PS, NRD, NRS, OFF, IC, and T.  They are described below:&lt;br /&gt;

There are five different default models: square-law I-V characteristic, analytical, semi-empirical, and BSIM and BSIM2 (Berkeley Short-channel IGFET Model), which include second-order effects such as channel-length&lt;br /&gt;
modulation, subthreshold conduction, scattering-limited velocity saturation, small-size effects, and charge-controlled capacitance.  The process parameter LEVEL specifies which of the models is chosen as indicated below:&lt;br /&gt;

==Mutual Inductors==&lt;br /&gt;
&lt;br /&gt;
[[File:GK100.png]]&lt;br /&gt;
&lt;br /&gt;
The mutual inductors device is a pair of inductors that are coupled to each other.  L1 and L2 are the names of two inductors. You have to specify the inductance of inductor L1, the inductance of inductor L2, the initial current through each, and the coupling coefficient k, 0 &amp;amp;le; k &amp;amp;le; 1. The mutual inductance M expressed in units of H can be calculated using the following definition:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; k = \frac{M}{\sqrt{L_1 L_2}} &amp;lt;/math&amp;gt;&lt;br /&gt;

==Non-Ideal Current Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK104.png]]&lt;br /&gt;
&lt;br /&gt;
This 8-pin device models a non-ideal lossy current transformer. Its model consists of an ideal transformer with more secondary turns than primary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. on each side of the internal ideal transformer, there is a series leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, followed by a shunt winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a series winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, which connects to the exterior positive pin on that side. The inter-winding resistance R&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the negative pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance. &lt;br /&gt;

&lt;br /&gt;
This 2-pin device is a basic simplified model of a diode as a rectifier or switch. When forward-biased, it acts as a low-valued voltage source. When reverse-biased, it acts as an open circuit until the reverse voltage exceeds the specified breakdown voltage. Then it acts as a high-valued voltage source of the reverse polarity. &lt;br /&gt;

&lt;br /&gt;
[[File:GK103.png]]&lt;br /&gt;
&lt;br /&gt;
This 8-pin device models a non-ideal lossy voltage transformer. Its model consists of an ideal transformer with more primary turns than secondary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. There are series combinations of a winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; on the primary and secondary sides. These are connected between the positive interior and exterior pins on each side. There are also two shunt branches at the inputs of the primary and secondary sides (connected between the positive and negative exterior pins), each consisting of a distributed turn-to-turn winding resistance RDC&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; in series with a distributed turn-to-turn winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;. The inter-winding capacitance CWW&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the positive pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance.  &lt;br /&gt;

==Nonlinear Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK89.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear capacitor model allows the capacitor to be described by an arbitrary relationship between the capacitor's charge Q and the voltage V across the capacitor. In other words, Q = f(V). The nonlinear capacitance is then defined as C(V) = dQ/dV. You need to define the charge Q by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ C_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear capacitor, where Q = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, C = C(V) = dQ/dV = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Conductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK88.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear conductor model allows the conductor to be described by an arbitrary relationship between the conductor's current I and the voltage V across the conductor. In other words, I = f(V). The nonlinear conductance is then defined as G(V) = dI/dV. You need to define the current I by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ G_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear conductor, where I = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, G = G(V) = dI/dV = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Dependent Sources==&lt;br /&gt;
&lt;br /&gt;
[[File:G18.png]]&lt;br /&gt;
&lt;br /&gt;
Nonlinear dependent (arbitrary) sources use an equation or mathematical expression to describe their behavior. One and only one of the two forms: V=&amp;amp;lt;expr&amp;amp;gt; or  I=&amp;amp;lt;expr&amp;amp;gt; must be given.&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; v = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; i = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Examples: &lt;br /&gt;
&lt;br /&gt;
v = I(v1) + 3* I(v2)&lt;br /&gt;
&lt;br /&gt;
I = v(i1) + 3* v(2) + 5 * v(3) ^2&lt;br /&gt;
&lt;br /&gt;
The first example is a current-controlled voltage source.  The v on the left side of the equation&lt;br /&gt;
indicates that it is a voltage source.  I(v1) and I(v2) are the currents through voltage sources named v1 and v2, respectively.&lt;br /&gt;
&lt;br /&gt;
The second example is a voltage-controlled current source.  v(2) and v(3) represents the voltages at nodes 2 and 3, respectively, and v(i1) represents the voltage across a current source named i1.&lt;br /&gt;
&lt;br /&gt;
The following mathematical functions defined for real variables can be used in the expressions:&lt;br /&gt;
&lt;br /&gt;
abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), atanh(x), cos(x), cosh(x), exp(x), ln(x), log(x), max(x,y), min(x,y), pwr(x,y), pwrs(x,y), sgn(x), sin(x), sinh(x), sqrt(x), tan(x), tanh(x), u(x), uramp(x).&lt;br /&gt;
&lt;br /&gt;
The function &amp;amp;quot;sgn&amp;amp;quot; is the signum function and its value is 1 if the argument is positive or zero and -1 if the argument is negative. &lt;br /&gt;
The function &amp;amp;quot;u(x)&amp;amp;quot; is the unit step and &amp;amp;quot;uramp(x)&amp;amp;quot; is the integral of the unit step.  The&lt;br /&gt;
unit step is one if its argument is greater than zero and zero if its argument is less than zero.  The&lt;br /&gt;
ramp function (uramp) is 0 for argument values less than zero and equal to the argument for argument values&lt;br /&gt;
greater than zero.&lt;br /&gt;
&lt;br /&gt;
The following operators are permissible:  +, -, *, /, and ^.&lt;br /&gt;
&lt;br /&gt;
The power functions have equivalent expressions: pwr(x,y) = x^y and pwrs(x,y) = sgn(x)*abs(x)^y.&lt;br /&gt;
&lt;br /&gt;
Two constants can also be used in expressions: pi = 3.1415926 and e = 2.7182818.&lt;br /&gt;
&lt;br /&gt;
There is a conditional function with the syntax IF(Condition, Expression1, Expression2). If &amp;quot;Condition&amp;quot; is met, then the return value of the function is Expression1; otherwise, it is Expression2. An example of this type of function is IF(v(1)&amp;gt;=0,1,-1), which is equivalent to sgn(v(1)). &lt;br /&gt;
&lt;br /&gt;
To get time into an expression, integrate the current from a constant current source with a capacitor&lt;br /&gt;
and use the voltage across the capacitor.&lt;br /&gt;
&lt;br /&gt;
Note: All the functions and expressions are case-insensitive.&lt;br /&gt;
&lt;br /&gt;
==Nonlinear Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK90.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear inductor model allows the inductor to be described by an arbitrary relationship between the inductor's magnetic flux &amp;amp;Phi; and the current I flowing through the inductor . In other words, &amp;amp;Phi;  = f(I). The nonlinear inductance is then defined as L(I) = d&amp;amp;Phi;/dI. You need to define the flux &amp;amp;Phi; by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ L_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear inductor, where &amp;amp;Phi; = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, L = L(I) = d&amp;amp;Phi;/dI = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.  &lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(i(vx))^2.&lt;br /&gt;

==Nonlinear Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK87.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear resistor model allows the resistor to be described by an arbitrary relationship between the voltage V across the resistor and its current I. In other words, V = f(I). The nonlinear resistance is then defined as R(I) = dV/dI. You need to define the voltage V by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ R_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear resistor, where V = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, R = R(I) = dV/dI = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 10*(i(vx))^2.&lt;br /&gt;

==Operational Amplifier (Op-Amp)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK105.png]]&lt;br /&gt;
&lt;br /&gt;
This three-pin device models a parameterized operational amplifier with a very high voltage gain, a very high input impedance and a very low output impedance. The behavioral model of the parameterized Op-Amp device is based on the algorithm found in the book &amp;lt;B&amp;gt;Macromodeling with Spice&amp;lt;/B&amp;gt;,&lt;br /&gt;
authored by Connelly &amp;amp;amp; Choi, published by Prentice Hall. The default parameters are those of the 741 Op-Amp. This device doesn't require external DC bias voltage sources. Its positive and negative DC bias voltages are specified as its parameters. Sometimes the simulation doesn't converge if there is no DC path from the output of the Op-Amp to the ground.&lt;br /&gt;

== Optocoupler ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK115.png]]&lt;br /&gt;
&lt;br /&gt;
This is a five-pin parameterized optocoupler device. Its model consists of an ideal diode device in series with an Ohmic resistance connected between the Anode (A) and Cathode (K) pins together with a bipolar junction transistor device with three accessible pins, Collector (C), Base (B) and Emitter (E). A current-controlled current source is connected between base and collector of the BJT, whose current is controlled by the current passing through the diode. The proportionality constant is twice the specified value of the current transfer ratio (ctr) parameter. &lt;br /&gt;
&lt;br /&gt;
You can change or enhance the models of the diode and BJT by adding more parameters. To do so, you have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

[[File:GK113.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 4-pin parameterized photodiode device. A pair of pins, Anode (A) and Cathode (K), represent the physical terminals of the photodiode. The photodiode model connected between the anode and cathode pins consists of the parallel connection of an ideal diode, a dark current source, a noise current source, a current-controlled current source, a diode capacitance, a shunt resistance altogether with a series resistance.  &lt;br /&gt;
&lt;br /&gt;
Another pair of pins IS+ and IS- act as an ammeter that must be inserted in a control circuit. The current passing through this ammeter controls the current of the photodiode. The default proportionality constant is unity. The controlling current is typically a function of light intensity incident on the surface of the photodiode.    &lt;br /&gt;

==Piecewise Linear (PWL) Controlled Source==&lt;br /&gt;
&lt;br /&gt;
[[File:GL49.png]]&lt;br /&gt;
&lt;br /&gt;
The Piecewise Linear (PWL) Controlled Source is a single-input and single-output function generator whose output is not necessarily&lt;br /&gt;
linear for all input values. Instead, it follows an I/O relationship that is specified by the x_array and y_array coordinates. The x_array and y_array values represent vectors of coordinate points on the x and y axes, respectively. The x_array values are progressively increasing input coordinate points, and the associated y_array values represent the outputs at those points.  There may be as few as two pairs specified, or as many as memory and simulation speed allow.&lt;br /&gt;
&lt;br /&gt;
In order to fully specify outputs for values of Vin outside of the bounds of the PWL function, the PWL&lt;br /&gt;
controlled source model extends the slope found between the lowest two coordinate pairs and the highest&lt;br /&gt;
two coordinate pairs.  This has the effect of making the transfer function completely linear for Vin&lt;br /&gt;
less than x_array[0] and Vin greater than x_array[n]. It also has the potentially subtle effect of unrealistically&lt;br /&gt;
causing an output to reach a very large or small value for large inputs. You should thus keep in mind&lt;br /&gt;
that the PWL Source does not inherently provide a limiting capability.&lt;br /&gt;
&lt;br /&gt;
In order to diminish the potential for divergence of simulations when using the PWL block, a form&lt;br /&gt;
of smoothing around the x_array and y_array coordinate points is necessary.  This is due to the iterative&lt;br /&gt;
nature of the simulator and its reliance on smooth first derivatives of  transfer functions in order to&lt;br /&gt;
arrive at a matrix solution.  Consequently, the two parameters &amp;quot;input_domain&amp;quot; and &amp;quot;fraction&amp;quot; are included&lt;br /&gt;
to allow you some control over the amount and nature o the smoothing performed.&lt;br /&gt;
&lt;br /&gt;
Fraction is a switch that is either TRUE or FALSE.  When TRUE (the default setting), the simulator assumes&lt;br /&gt;
that the specified input_domain value is to be interpreted as a fractional figure.  Otherwise, it is interpreted&lt;br /&gt;
as an absolute value.  Thus, if fraction = TRUE and input_domain = 0.10, the simulator assumes that the smoothing&lt;br /&gt;
radius about each coordinate point is to be set equal to 10% of the length of either the x_array segment&lt;br /&gt;
above each coordinate point, or the x_array segment below each coordinate point. The specific segment&lt;br /&gt;
length chosen will be the smallest of these two for each coordinate point.&lt;br /&gt;
&lt;br /&gt;
If fraction = FALSE and input_domain = 0.10, then the simulator will begin smoothing the transfer function at 0.10&lt;br /&gt;
volts (or amperes) below each x_array coordinate and will continue the smoothing process for another 0.10&lt;br /&gt;
volts (or amperes) above each x_array coordinate point.&lt;br /&gt;

== Programmable Unijunction Transistor (PUT)==&lt;br /&gt;

[[File:GK112.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Programmable Unijunction Transistor (PUT) device with three pins: Base 1 (B1), Base 2 (B2) and Emitter (E). It is biased with a positive voltage between the two bases. This device has a unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. It exhibits a negative resistance characteristic and so it can be employed as an oscillator. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively. To change these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.    &lt;br /&gt;

==Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK119.png]]&lt;br /&gt;
&lt;br /&gt;
Resistors are passive devices that dissipate power. Their resistance value varies depending on how much power they can dissipate and is measured&lt;br /&gt;
in Ohms.  The transient, DC and AC behaviors of a resistor are all described by the same equation:&lt;br /&gt;
&lt;br /&gt;
v = R * i&lt;br /&gt;
&lt;br /&gt;
where v is the voltage across the resistor, i is the current passing through the resistor, and R is the resistance. The value of R must be nonzero. &lt;br /&gt;
&lt;br /&gt;
All resistor names must begin with R.&lt;br /&gt;

&lt;br /&gt;
Example: &lt;br /&gt;
&lt;br /&gt;
R1 1 2 1k&lt;br /&gt;
&lt;br /&gt;
[[RF.Spice A/D]] provides three types of resistor: Simple, User-Defined (Real Resistor) and Semiconductor. The resistance of the simple resistor is a single value expressed in Ohms. You can also set the Monte Carlo tolerance for this resistor.&lt;br /&gt;
&lt;br /&gt;
==Schottky Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK80.png]]&lt;br /&gt;
&lt;br /&gt;
The Schottky diode has the same model as the generic diode with a nonzero transit time (tt), a nonzero junction capacitance (cjo) and a typically larger saturation current (is), a lower junction potential (vj) and a smaller grading coefficient (m).   &lt;br /&gt;
&lt;br /&gt;
==Semiconducting Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK83.png]]&lt;br /&gt;
&lt;br /&gt;
This is the more general form of the Capacitor model and allows for the calculation of the actual capacitance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
CXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;IC=VAL&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it defines the capacitance. If MNAME is specified, then the capacitance is calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. Either VALUE or MNAME, LENGTH, and WIDTH may be specified, but not both sets. The optional initial condition &amp;quot;IC&amp;quot; is the initial voltage across the capacitor for transient simulations.&lt;br /&gt;
&lt;br /&gt;
The capacitance is computed as:&lt;br /&gt;
&lt;br /&gt;
CAP = CJ * (LENGTH - NARROW) * (WIDTH - NARROW)+ 2 * CJSW * (LENGTH + WIDTH - 2NARROW) * CAP&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the capacitor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit CJ, CJSW, NARROW, DEFW, and CAP.&lt;br /&gt;

== Semiconductor Resistor ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK82.png]]&lt;br /&gt;
&lt;br /&gt;
This is the more general form of the resistor model and allows for the modeling of temperature effects and for the calculation of the actual resistance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
RXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;TEMP=T&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it overrides the geometric information and defines the resistance. If MNAME is specified, then the resistance may be calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. The (optional) TEMP value is the temperature at which this device is to operate, and overrides the temperature specification in the SPICE Options Dialog. &lt;br /&gt;
&lt;br /&gt;
The resistance is computed as:&lt;br /&gt;
&lt;br /&gt;
R(T0) = (RSH) * [(L - NARROW) / (W - NARROW)] * RES&lt;br /&gt;
&lt;br /&gt;
R(T) = R(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the resistor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit TC1, TC2, RSH, RES, etc.&lt;br /&gt;

&lt;br /&gt;
[[File:GL14.png]]&lt;br /&gt;
&lt;br /&gt;
This is a current source whose current is an arbitrary function of the circuit temperature. You have to open the subcircuit model dialog by clicking the {{key|Edit Model...}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(T)&amp;quot; standing for temperature.

== Triac Thyristor ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK110.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin bidirectional thyristor device that conducts current in either direction when triggered. A thyristor is analogous to a relay in that a small voltage and current can control a much larger voltage and current. The triac has two anode pins termed Main Terminal 1 (MT1) and Main Terminal 2 (MT2) and a Gate (G) pin. In order to create a triggering current for a triac, either a positive or negative voltage can be applied to the gate. Once triggered, the thyristor continues to conduct, even if the gate current ceases, until the main current drops below a certain level called the holding current. The device's model involves two NPN BJT transistors and two PNP BJT transistors. The forward beta parameters of the NPN and PNP transistors are set equal to 20 and 5, respectively. To changes these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.&lt;br /&gt;

==Uniform RC Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G23.png]]&lt;br /&gt;
&lt;br /&gt;
The standard parameters are L, and N.  They are described below:&lt;br /&gt;
&lt;br /&gt;
Two of the nodes are the element nodes connected by the RC line.  The third is the node to which the capacitances&lt;br /&gt;
are connected.  L is the length of the RC line in meters.  N is the number of lumped segments to use in&lt;br /&gt;
modeling the RC line.&lt;br /&gt;
&lt;br /&gt;
This device is derived from a model proposed by Gertzberrg.  It expands the URC line into a network of&lt;br /&gt;
lumped RC segments with internally generated nodes.  These segments increase toward the middle of the&lt;br /&gt;
URC line in a geometric progression with K as the proportionality constant.&lt;br /&gt;
&lt;br /&gt;
The URC line is made up entirely of resistor and capacitor segments, unless the ISPERL parameter has a&lt;br /&gt;
non-zero value.  In this case, capacitors are replaced by reverse biased diodes with an equivalent zero-bias&lt;br /&gt;
junction capacitance, a saturation current of ISPERL amps per meter of transmission line, and optional&lt;br /&gt;
series resistance of RSPERL ohms per meter. &lt;br /&gt;

==Voltage-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G19.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Voltage-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Voltmeter or controlling voltage nodes, as well as the turn-on and turn-off voltages in Volts and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the rest of [[parameters]]. When the voltage across the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the voltage across the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Voltage Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17A.png]]&lt;br /&gt;
&lt;br /&gt;
A voltage source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a voltage source is its initial transient value. For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset voltage. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;

==Zener Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:G10.png]]&lt;br /&gt;
&lt;br /&gt;
The Zener Diode models the DC characteristics of most zeners. Since most data sheets for zener diodes do&lt;br /&gt;
not give detailed characteristics in the forward region, only a single point defines the forward characteristicThe&lt;br /&gt;
saturation current refers to the relatively constant reverse current that is produced when the voltage&lt;br /&gt;
across the zener is negative, but breakdown has not been reached.  The reverse leakage current determines&lt;br /&gt;
the slight increase in reverse current as the voltage across the zener becomes more negative.  It is modeled&lt;br /&gt;
as a resistance parallel to the zener with value v_breakdown / i_rev.&lt;br /&gt;
&lt;br /&gt;
Note that the limt_switch parameter engages an internal limiting function for the zener.  This can, in&lt;br /&gt;
some cases, prevent the simulator from converging to an unrealistic solution if the voltage across or&lt;br /&gt;
current into the device is excessive.  If use of this feature fails to yield acceptable results, the convlimit&lt;br /&gt;
option should be tried (add the following statement to the SPICE input deck:  .options convlimit)&lt;br /&gt;

==Analog-to-Digital Converter (ADC) Bridge==&lt;br /&gt;
[[File:GK42.png]]&lt;br /&gt;
&lt;br /&gt;
The ADC Bridge takes an analog value from an analog node and may be in the form of a voltage or current.&lt;br /&gt;
If the input is less than or equal to &amp;amp;quot;in_low&amp;amp;quot;, then a digital &amp;amp;quot;0&amp;amp;quot; is generated. If&lt;br /&gt;
the input is greater than or equal to &amp;amp;quot;in_high&amp;amp;quot;, a digital &amp;amp;quot;1&amp;amp;quot; is generated. Otherwise,&lt;br /&gt;
a digital &amp;amp;quot;UNKNOWN&amp;amp;quot; is the output value. Unlike the DAC Bridge, ramping or delay is not applicable.&lt;br /&gt;
Rather, the continuous ramping of the input provides for any associated delays in the digitized signal.&lt;br /&gt;
&lt;br /&gt;
This model also posts an input load value based on the parameter input_load.&lt;br /&gt;

==Bipolar Junction Transistor (BJT)==&lt;br /&gt;
[[File:G11.png]]&lt;br /&gt;
&lt;br /&gt;
The BJT is an active device which has up to 4 pins.  The three standard pins are base, emitter, and collector.  These are given in the default symbol.  The substrate, which is grounded by default, is the fourth pin.  To use the BJT with the substrate, create a new 4-pin BJT using the Device Editor and Symbol Editor.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|AREA||area factor (optional) (If not specified, the default value is 1.0.)&lt;br /&gt;
|-&lt;br /&gt;
|OFF||initial condition for the DC analysis (optional)&lt;br /&gt;
|-&lt;br /&gt;
|IC||initial condition (optional) (Used when a transient analysis is desired, which starts from other than the quiescent operating point.)&lt;br /&gt;
|-&lt;br /&gt;
|T||operating temperature of the device (optional)&lt;br /&gt;
|-&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Area factor scales the model parameters RE and RC.  IC VBE is the initial voltage from base emitter. IC VCE is the initial voltage from collector to emitter.  TEMP is the overriding temperature. These parameters are based on the Gummel and Poon integral-charge model.  If these parameters are not specified, then it will reduce to the simpler Ebers-Moll model. &lt;br /&gt;
&lt;br /&gt;
The process model is mandatory for the BJT.  Descriptions of the process model parameters are given in the following table:&lt;br /&gt;

==Capacitance Meter==&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Capacitance Meter measures the total capacitance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total capacitance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense a capacitance value and alter their behavior based upon it.&lt;br /&gt;

==Capacitor==&lt;br /&gt;
[[File:GK120.png]]&lt;br /&gt;
&lt;br /&gt;
Capacitors are used to store electrical energy.  They can filter or remove AC signals or block DC current without disrupting AC signals. A capacitor's ability to store energy is termed capacitance and is measured in Farads, with values from pF to mF. The only time current flows through a capacitor is when the charge is collected on, or is removed from, its parallel plates. This means that the voltage across the capacitor is changing, which doesn't conform to DC analysis. In a physical circuit, there is a transition stage during which capacitors charge up to their final values. The result is the same as if these capacitors did not exist and the connections to them were left dangling. In other words, in a (steady-state) DC analysis, a capacitor behaves like an open circuit. Therefore, it is important that no section of the circuit is isolated from the capacitors. Every circuit node needs some path for DC current to the ground.&lt;br /&gt;
&lt;br /&gt;
A capacitor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
i(t) = C * (dv(t)/dt)&lt;br /&gt;
&lt;br /&gt;
Its initial voltage is only important when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked.&lt;br /&gt;
&lt;br /&gt;
An capacitor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
i = j ω * C * v &lt;br /&gt;
&lt;br /&gt;
All capacitor names must begin with C. &lt;br /&gt;

[[RF.Spice A/D]] provides three types of capacitors: simple, user-defined (or real) and semiconductor. The standard capacitor parameters are N+, N-, VALUE, and IC. In a simple capacitor, VALUE must&lt;br /&gt;
be specified for the capacitance in Farads. IC is the (optional) initial condition for the capacitor voltage.&lt;br /&gt;

==Center-Tapped Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK97.png]]&lt;br /&gt;
&lt;br /&gt;
This five-pin three-port device models a center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;
&lt;br /&gt;

==Current Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17B.png]]&lt;br /&gt;
&lt;br /&gt;
Current source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a current source is its initial transient value.  For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset current. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==Current-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G20.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Current-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the turn-on and turn-off currents in Amperes and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the rest of [[parameters]]. When the current through the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the current through the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Darlington Pair==&lt;br /&gt;
&lt;br /&gt;
[[File:GK108.png]]&lt;br /&gt;
&lt;br /&gt;
A Darlington pair is a three-pin device that consists of two interconnected BJT transistors of the same type. The collectors of two transistors are connected together to provide the &amp;quot;Collector&amp;quot; pin of the pair. The base of the first BJT acts the &amp;quot;Base&amp;quot; pin of the pair. The emitter of the first BJT is internally connected to the base of the second BJT. The emitter of the second BJT acts as the &amp;quot;Emitter&amp;quot; pin of the pair. There are two types of Darlington pair: NPN and PNP. The parameterized generic Darlington pair also contains a diode connected between the collector and emitter pin as well as two base-emitter resistors, one across each BJT.     &lt;br /&gt;

==D Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G52.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type flip-flop is a one-bit, edge-triggered storage element which stores data whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). In addition, there are asynchronous set and reset signals, which are independent of the clock. When SET = RESET = 0, the data on the D line is transferred to the output Q on the rising edge of the clock. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

&lt;br /&gt;
The digital D-type latch is a one-bit, level-sensitive storage element which outputs the value on the data (D) line whenever the enable (EN) input line is 1 (high). The value on the data line is stored, i.e., held on the output (Q) line whenever the enable (EN) line is 0 (low). In addition, there are set and reset signals, which are independent of the enable line. When SET = RESET = 0, the data on the D line is transferred to the output Q whenever EN = 1. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

==Frequency Meter==&lt;br /&gt;
[[File:G114.png]]&lt;br /&gt;
&lt;br /&gt;
The Frequency Meter is a four-pin shunt device that is connected in parallel with an AC source just like a voltmeter and measures the operating frequency of the AC circuit. The input pins are connected across the AC source. The voltage across the output pins is equal to the frequency of the source in Hertz within a scale factor SF. Note that the Frequency Meter is designed to work with a single-tone AC source of unit amplitude. If the amplitude of the source is not one, multiply the SF parameter by the non-unit source amplitude value. The output voltage of the Frequency Meter can be used in conjunction with linear or nonlinear dependent sources to model frequency-dependent quantities.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Model Identifier: fmeter&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Parameters:&lt;br /&gt;
&lt;br /&gt;
The only parameter is the scale factor SF with a default value of 1.0. Set SF = 1e-6 to read out the frequency in MHz. Set SF = 1e-9 to read out the frequency in GHz. Set SF = 6.283185 (2*pi) to read out the angular frequency &amp;amp;omega; in radian/s.  &lt;br /&gt;
&lt;br /&gt;
== Fuse ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK76.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 2-pin interactive current-controlled switch. If the current passing through the fuse is less than a specified threshold current, the switch is closed. If the current exceeds the threshold level, the fuse breaks and remains open thereafter. The device's symbol changes to display its state.   &lt;br /&gt;

&lt;br /&gt;
Ground has a voltage of zero (0) and is used as a reference to compute electrical values in the circuit. &lt;br /&gt;
All circuits &amp;lt;B&amp;gt;must&amp;lt;/B&amp;gt; be grounded to be properly simulated.  There is no limit on the number of grounds&lt;br /&gt;
you may use in a circuit.  All components connected to ground are referenced to a common point and treated&lt;br /&gt;
as linked through ground.&lt;br /&gt;

==Hysteresis Block (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Hysteresis block is a simple buffer stage that provides hysteresis of the output with respect to the&lt;br /&gt;
input.  The in_low and in_high parameter values.  The output values are limited to out_lower_limit and&lt;br /&gt;
out_upper_limit.  The value of \93hyst\94 is added to the in_low and in_high points in order to specify the&lt;br /&gt;
points at which the slope of the hysteresis function would normally change abruptly as the input transitions&lt;br /&gt;
from a low to a high value.  Likewise, the value of \93hyst\94 is subtracted from the in_high and in_low values&lt;br /&gt;
in order to specify the points at which the slope of the hysteresis function would normally change abruptly&lt;br /&gt;
as the input transitions from a high to a low value.  In fact, the slope of the hysteresis function is&lt;br /&gt;
never allowed to change abruptly but is smoothly varied whenever the input_dowmain smoothing parameter&lt;br /&gt;
is set greater than zero.&lt;br /&gt;

==Ideal Center-Tapped Transformer with Push-Pull Input==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR4.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal center-tapped transformer with push-pull input is a five-pin three-port device with two primary input ports and one secondary output port. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P1}{v_S} = \frac{v_P2}{v_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; is the secondary voltage, v&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt; is measured between the top primary pin P1 and the center tap pin, and v&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom primary pin P2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.        &lt;br /&gt;

where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; is the primary voltage, v&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; is measured between the top secondary pin S1 and the center tap pin, and v&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom secondary pin S2. The red dots show the polarity of the windings on each side.

&lt;br /&gt;
This is a six-pin, three-port device that models an ideal microwave circulator. There are two types of this device: Clockwise Circulator and Counterclockwise Circulator .

This 2-pin device is a very basic and primitive model of a diode as a rectifier or switch. When the voltage across the device's terminals is positive, it acts as a short circuit. When the voltage across the device's terminals is negative, it acts as an open circuit.   &lt;br /&gt;

==Ideal Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR1.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal transformer is a four-pin two-port device with the following relationship between the voltages and currents at its primary and secondary ports:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_S} = - \frac{i_S}{i_P} = \frac{N_P}{N_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; are the primary voltage, current and number of turns, respectively, and v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; are the secondary voltage, current and number of turns, respectively. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary turns ratio. Note that the ideal transformer model is defined based on controlled sources and does not involve any magnetic physical parameters as opposed to mutual inductors or ferrite core transformer.&lt;br /&gt;
&lt;br /&gt;
==Inductance Meter==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductance Meter measures the total inductance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total inductance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense an inductance value and alter their behavior based upon it. Care must be exercised when connecting an Inductance Meter to the inductors of a circuit. This is due to the fact that inductors are treated by SPICE as current sources. This can cause a problem when an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. &lt;br /&gt;

==Inductive Coupler Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GK99.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductive Coupler Block couples any two existing inductors. This block doesn't have any pins because it doesn't actually represent inductors, only the coupling between them. This is useful if you want to&lt;br /&gt;
couple two inductors that are in different parts of the circuit, or if you want to couple more than two inductors together. In the latter case, use more than one of these, with each one coupling a pair of inductors.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are Inductor1, Inductor2, and k. Inductor1 is the name of first inductor, Inductor2 is the name of the second inductor, and k is the coefficient of coupling, 0 &amp;amp;lt; k &amp;amp;le; 1.&lt;br /&gt;
&lt;br /&gt;
==Inductive Coupling (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G41.png]]&lt;br /&gt;
&lt;br /&gt;
This function is a conceptual model which is used as a building block to create a wide variety of inductive and magnetic circuit models. This function is normally used in&lt;br /&gt;
conjunction with the “core” model, but it can also be used with resistors, hysteresis blocks, etc. to build up systems which mock the behavior of linear and nonlinear components.&lt;br /&gt;
The lcouple takes as an input (on the “l” port) a current. This current value is multiplied by the num_turns value, N, to produce an output value (a voltage value which appears on the&lt;br /&gt;
mmf_out port). The mmf_out acts similar to a magnetomotive force in a magnetic circuit;&lt;br /&gt;
when the lcouple is connected to the “core” model, or to some other resistive device, a current will flow. This current value (which is modulated by whatever the lcouple is&lt;br /&gt;
connected to) is then used by the lcouple to calculate a voltage “seen” at the “l” port. The voltage is a function of the derivative with respect to time of the current value seen at mmf_out.&lt;br /&gt;
&lt;br /&gt;
The most common use for lcouple will be as a building block in the construction of transformer models. To create a transformer with a single input and a single output, you&lt;br /&gt;
would require two lcouple models plus one “core” model. &lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
A1 (1 0) (2 3) lcouple1&lt;br /&gt;
&lt;br /&gt;
.model lcouple1 lcouple ( num_turns = 10 )&lt;br /&gt;

==Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK121.png]]&lt;br /&gt;
&lt;br /&gt;
Inductors are used to store magnetic energy. An inductor's ability to counteract current changes passing through it is called its inductance (L), which is&lt;br /&gt;
measured in Henrys. In a (steady-state) DC analysis, the inductor acts like a short circuit. It is indeed treated as a current source, which can be problematic if an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. The resistor may be of negligible value or one that accounts for the coil resistance of the inductor. In AC and transient analyses, the inductor develops a voltage across it in response to the changing magnetic&lt;br /&gt;
flux within its coil. &lt;br /&gt;
&lt;br /&gt;
An inductor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
v(t) = L*(di(t)/dt) &lt;br /&gt;
&lt;br /&gt;
The inductor's initial condition is optional. It is the initial value of the inductor current in Amperes that flows from node N+ through the inductor to node N-. The only time that the initial current matters is when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked. &lt;br /&gt;
&lt;br /&gt;
An inductor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
v = j &amp;amp;omega; * L * i&lt;br /&gt;
&lt;br /&gt;
All inductor names must begin with L.&lt;br /&gt;

==Inductor with Ferrite Core==&lt;br /&gt;
&lt;br /&gt;
[[File:GK94.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device models a physical inductor with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. Unlike the standard inductor device, you do not specify an inductance value for the inductor with ferrite core. Rather, you specify physical parameters like cross sectional area, core length and number of turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;

== Insulated Gate Bipolar Transistor (IGBT)==&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Insulated Gate Bipolar Transistor (IGBT) device with three pins: Collector(C), Gate (G), and Emitter (E). It is primarily used as a fast electronic switch. The IGBT combines the simple gate-drive characteristics of MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors. The device's model consists of an isolated gate FET for the control input, and a PNP bipolar power transistor as a switch.

==Junction Field Effect Transistor (JFET)==&lt;br /&gt;
&lt;br /&gt;
[[File:G12.png]]&lt;br /&gt;
&lt;br /&gt;
The JFET is the simplest transistor device and has three pins: gate, drain and source. The JFET defaults are based on the Shichman and Hodges FET model. This is a square-law device because of the expression relating the drain current to the gate-to-source voltage: &lt;br /&gt;
Idrain=*(VGS-Vthreshold)2.  In real JFETs, near the saturation point, the drain currents vary with the drain voltages. This can be modeled by the following formula:  Idrain=*(VGS-VTO)2*(1+*VDS), which yields an increasing&lt;br /&gt;
drain current for increasing values of VDS.&lt;br /&gt;
&lt;br /&gt;
The gate-to-source and gate-to-drain junctions each have a nonlinear capacitor.  The zero-bias capacitance value is selected for each junction.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

==Linear Current-Controlled Current Source (CCCS)==&lt;br /&gt;
&lt;br /&gt;
[[File:G2.png]]&lt;br /&gt;
&lt;br /&gt;
The CCCS is a current source whose current is directly proportional to the current across a controlling Ammeter or a voltage source. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the current gain, which has a default value of one. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the current gain.   &lt;br /&gt;

==Lossless Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G21.png]]&lt;br /&gt;
&lt;br /&gt;
The lossless transmission line is a four-pin two-port device that models only one propagating mode of an ideal transmission line.  When using this SPICE model, should all four nodes of the actual circuit be distinct, two modes may be activated, and this device would be insufficient for that purpose. To circumvent this potential problem, two transmission line devices would be required. Due to the implementation details, you may produce more accurate simulation results with a lossy transmission line device with zero loss.&lt;br /&gt;
&lt;br /&gt;
Optional initial condition parameters are the voltage and current at each of the transmission line ports.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are Z0, TD, F, NL, IC, described below:&lt;br /&gt;

==Lossy Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G22.png]]&lt;br /&gt;
&lt;br /&gt;
The lossy transmission line is a four-pin two-port convolution model for uniform constant-parameter distributed lines. MNAME is the process model name, which&lt;br /&gt;
includes a set of pre-specified options as described below.&lt;br /&gt;
&lt;br /&gt;

The RLC (uniform transmission line with series loss only), RC (uniform RC line), LC (lossless transmission&lt;br /&gt;
line), and RG (distributed series resistance and parallel conductance only) lines have been implemented. &lt;br /&gt;
The length (LEN) must be given.  COMPACTREL and COMPACTABS control the compaction of past history values&lt;br /&gt;
used in convolution.  Larger values for these lower accuracy but improve speed.  These are used with the&lt;br /&gt;
TRYTOCOMPACT option. &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Magnetic Core (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G42.png]]&lt;br /&gt;
&lt;br /&gt;
This device is used as a building block to create a wide variety of inductive and magnetic circuit models. It is almost always to be used in conjunction with the &amp;quot;lcouple&amp;quot; model to build up systems which simulate the behavior of linear and nonlinear magnetic components. There are two fundamental modes of operation for the core model. These are the &amp;quot;PWL&amp;quot; mode (which is the default and most&lt;br /&gt;
likely to be of use to you) and the &amp;quot;Hysteresis&amp;quot; mode.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;PWL Mode (mode = 1)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the PWL mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf) value. This value is divided by the total effective length of the core to produce a value for the Magnetic Field Intensity, H, which is then used to find the corresponding Flux Density, B, using the piecewise linear relationship described by you in the H_array / B_array coordinate pairs. B is then multiplied by the cross-sectional area of the core to find the Flux value, which is output as a current. The pertinent mathematical equations are:&lt;br /&gt;
&lt;br /&gt;
H = mmf / L, where L = Length (in apmere-turns/meter)&lt;br /&gt;
&lt;br /&gt;
B = f(H)&lt;br /&gt;
&lt;br /&gt;
&amp;amp;Phi; = B * A, where A = Area&lt;br /&gt;
&lt;br /&gt;
The B value is derived from a piecewise linear transfer function described to the model by the H_array and B_array coordinate pairs.  This transfer function does not include hysteretic effects; for that, you would need to substitute a HYST model for the core. The magnetic flux value &amp;amp;Phi; in turn is used by the &amp;quot;lcouple&amp;quot;&lt;br /&gt;
code model to obtain a value for the voltage reflected back across its terminals to the driving electrical circuit.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Hysteresis Mode (mode = 2)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the Hysteresis mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf)&lt;br /&gt;
value.  This value is used as input to the equivalent of a hysteresis code model block.  The parameters&lt;br /&gt;
defining the input low and high values, the output low and high values, and the amount of hysteresis are&lt;br /&gt;
as in that model. The output from this mode, as in PWL mode, is a current value which is seen across the magnetic core port.&lt;br /&gt;
&lt;br /&gt;
One final note to be made about the two core models is that certain parameters are specific to one or the other.  In particular, the in_low, in_high, out_lower_limit, out_upper_limit, and hysteresis parameters are not available in PWL mode. Likewise, the H_array, B_array, area, ad length values are unavailable&lt;br /&gt;
in Hysteresis mode.  The input_domain and fraction parameters are common to both modes (though their behavior is somewhat different; for explanation of the input_domain and fraction values for the Hysteresis mode, please refer to the Hysteresis Block discussion.&lt;br /&gt;

[[File:G16.png]]&lt;br /&gt;
&lt;br /&gt;
The marker serves several purposes:&lt;br /&gt;
&lt;br /&gt;
* It can appear as a default plot in simulations if the &amp;amp;quot;Voltage Probe&amp;amp;quot; box is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to set the initial voltage or voltage guess at the node it is connected to.&lt;br /&gt;
&lt;br /&gt;
* It can be used as a port for a subcircuit when you choose the checkbox labeled &amp;quot;Use as Subcircuit Port&amp;quot; is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to explicitly set a node number in place of the arbitrarily assigned node number by the program. In this case, make sure the &amp;amp;quot;Set Node Index&amp;amp;quot; box is checked.  Otherwise, it will act as just a voltage probe.&lt;br /&gt;
&lt;br /&gt;
* It can be used to connect different parts of a circuit in place of wires. To use markers as virtual connectors, place them at points where wires would otherwise connect. Then set the Part Title of the two (or more) markers to the same name, and they will act as a single circuit node.&lt;br /&gt;

==MESFET==&lt;br /&gt;
&lt;br /&gt;
[[File:G14.png]]&lt;br /&gt;
&lt;br /&gt;
The MESFET is a Schottky-barrier gate FET with six times greater electron mobility than silicon.  MESFETs are important devices for creating high frequency circuits. They function by creating a potential barrier between the gate and the channel when the metal gate&lt;br /&gt;
contacts the gallium-arsenide substrate. Electron velocity saturates for fields approximately ten times lower than with silicon.  The Curtice model includes linear and saturated operation.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

&lt;br /&gt;
The MOSFET is an active device that has up to 4 pins.  The three standard pins are gate, drain, and source.  These are given in the default symbol.  The bulk node, which is grounded by default, is the fourth pin.  The MOSFET with the bulk is named mos_n_lvl1_4 (the lvl1 is for level 1, the n for nmos, and the 4 for 4 pins.)&lt;br /&gt;
&lt;br /&gt;
The standard [[parameters]] are L, W, AD, AS, PD, PS, NRD, NRS, OFF, IC, and T.  They are described below:&lt;br /&gt;

There are five different default models: square-law I-V characteristic, analytical, semi-empirical, and BSIM and BSIM2 (Berkeley Short-channel IGFET Model), which include second-order effects such as channel-length&lt;br /&gt;
modulation, subthreshold conduction, scattering-limited velocity saturation, small-size effects, and charge-controlled capacitance.  The process parameter LEVEL specifies which of the models is chosen as indicated below:&lt;br /&gt;

&lt;br /&gt;
The mutual inductors device is a pair of inductors that are coupled to each other.  L1 and L2 are the names of two inductors. You have to specify the inductance of inductor L1, the inductance of inductor L2, the initial current through each, and the coupling coefficient k, 0 &amp;amp;le; k &amp;amp;le; 1. The mutual inductance M expressed in units of H can be calculated using the following definition:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; k = \frac{M}{\sqrt{L_1 L_2}} &amp;lt;/math&amp;gt;&lt;br /&gt;

==Non-Ideal Current Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK104.png]]&lt;br /&gt;
&lt;br /&gt;
This 8-pin device models a non-ideal lossy current transformer. Its model consists of an ideal transformer with more secondary turns than primary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. on each side of the internal ideal transformer, there is a series leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, followed by a shunt winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a series winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, which connects to the exterior positive pin on that side. The inter-winding resistance R&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the negative pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance. &lt;br /&gt;

&lt;br /&gt;
This 2-pin device is a basic simplified model of a diode as a rectifier or switch. When forward-biased, it acts as a low-valued voltage source. When reverse-biased, it acts as an open circuit until the reverse voltage exceeds the specified breakdown voltage. Then it acts as a high-valued voltage source of the reverse polarity. &lt;br /&gt;

&lt;br /&gt;
This 8-pin device models a non-ideal lossy voltage transformer. Its model consists of an ideal transformer with more primary turns than secondary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. There are series combinations of a winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; on the primary and secondary sides. These are connected between the positive interior and exterior pins on each side. There are also two shunt branches at the inputs of the primary and secondary sides (connected between the positive and negative exterior pins), each consisting of a distributed turn-to-turn winding resistance RDC&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; in series with a distributed turn-to-turn winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;. The inter-winding capacitance CWW&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the positive pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance.  &lt;br /&gt;

==Nonlinear Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK89.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear capacitor model allows the capacitor to be described by an arbitrary relationship between the capacitor's charge Q and the voltage V across the capacitor. In other words, Q = f(V). The nonlinear capacitance is then defined as C(V) = dQ/dV. You need to define the charge Q by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ C_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear capacitor, where Q = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, C = C(V) = dQ/dV = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Conductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK88.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear conductor model allows the conductor to be described by an arbitrary relationship between the conductor's current I and the voltage V across the conductor. In other words, I = f(V). The nonlinear conductance is then defined as G(V) = dI/dV. You need to define the current I by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ G_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear conductor, where I = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, G = G(V) = dI/dV = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Dependent Sources==&lt;br /&gt;
&lt;br /&gt;
[[File:G18.png]]&lt;br /&gt;
&lt;br /&gt;
Nonlinear dependent (arbitrary) sources use an equation or mathematical expression to describe their behavior. One and only one of the two forms: V=&amp;amp;lt;expr&amp;amp;gt; or  I=&amp;amp;lt;expr&amp;amp;gt; must be given.&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; v = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; i = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Examples: &lt;br /&gt;
&lt;br /&gt;
v = I(v1) + 3* I(v2)&lt;br /&gt;
&lt;br /&gt;
I = v(i1) + 3* v(2) + 5 * v(3) ^2&lt;br /&gt;
&lt;br /&gt;
The first example is a current-controlled voltage source.  The v on the left side of the equation&lt;br /&gt;
indicates that it is a voltage source.  I(v1) and I(v2) are the currents through voltage sources named v1 and v2, respectively.&lt;br /&gt;
&lt;br /&gt;
The second example is a voltage-controlled current source.  v(2) and v(3) represents the voltages at nodes 2 and 3, respectively, and v(i1) represents the voltage across a current source named i1.&lt;br /&gt;
&lt;br /&gt;
The following mathematical functions defined for real variables can be used in the expressions:&lt;br /&gt;
&lt;br /&gt;
abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), atanh(x), cos(x), cosh(x), exp(x), ln(x), log(x), max(x,y), min(x,y), pwr(x,y), pwrs(x,y), sgn(x), sin(x), sinh(x), sqrt(x), tan(x), tanh(x), u(x), uramp(x).&lt;br /&gt;
&lt;br /&gt;
The function &amp;amp;quot;sgn&amp;amp;quot; is the signum function and its value is 1 if the argument is positive or zero and -1 if the argument is negative. &lt;br /&gt;
The function &amp;amp;quot;u(x)&amp;amp;quot; is the unit step and &amp;amp;quot;uramp(x)&amp;amp;quot; is the integral of the unit step.  The&lt;br /&gt;
unit step is one if its argument is greater than zero and zero if its argument is less than zero.  The&lt;br /&gt;
ramp function (uramp) is 0 for argument values less than zero and equal to the argument for argument values&lt;br /&gt;
greater than zero.&lt;br /&gt;
&lt;br /&gt;
The following operators are permissible:  +, -, *, /, and ^.&lt;br /&gt;
&lt;br /&gt;
The power functions have equivalent expressions: pwr(x,y) = x^y and pwrs(x,y) = sgn(x)*abs(x)^y.&lt;br /&gt;
&lt;br /&gt;
Two constants can also be used in expressions: pi = 3.1415926 and e = 2.7182818.&lt;br /&gt;
&lt;br /&gt;
There is a conditional function with the syntax IF(Condition, Expression1, Expression2). If &amp;quot;Condition&amp;quot; is met, then the return value of the function is Expression1; otherwise, it is Expression2. An example of this type of function is IF(v(1)&amp;gt;=0,1,-1), which is equivalent to sgn(v(1)). &lt;br /&gt;
&lt;br /&gt;
To get time into an expression, integrate the current from a constant current source with a capacitor&lt;br /&gt;
and use the voltage across the capacitor.&lt;br /&gt;
&lt;br /&gt;
Note: All the functions and expressions are case-insensitive.&lt;br /&gt;
&lt;br /&gt;
==Nonlinear Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK90.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear inductor model allows the inductor to be described by an arbitrary relationship between the inductor's magnetic flux &amp;amp;Phi; and the current I flowing through the inductor . In other words, &amp;amp;Phi;  = f(I). The nonlinear inductance is then defined as L(I) = d&amp;amp;Phi;/dI. You need to define the flux &amp;amp;Phi; by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ L_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear inductor, where &amp;amp;Phi; = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, L = L(I) = d&amp;amp;Phi;/dI = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.  &lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(i(vx))^2.&lt;br /&gt;

==Nonlinear Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK87.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear resistor model allows the resistor to be described by an arbitrary relationship between the voltage V across the resistor and its current I. In other words, V = f(I). The nonlinear resistance is then defined as R(I) = dV/dI. You need to define the voltage V by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ R_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear resistor, where V = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, R = R(I) = dV/dI = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 10*(i(vx))^2.&lt;br /&gt;

==Operational Amplifier (Op-Amp)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK105.png]]&lt;br /&gt;
&lt;br /&gt;
This three-pin device models a parameterized operational amplifier with a very high voltage gain, a very high input impedance and a very low output impedance. The behavioral model of the parameterized Op-Amp device is based on the algorithm found in the book &amp;lt;B&amp;gt;Macromodeling with Spice&amp;lt;/B&amp;gt;,&lt;br /&gt;
authored by Connelly &amp;amp;amp; Choi, published by Prentice Hall. The default parameters are those of the 741 Op-Amp. This device doesn't require external DC bias voltage sources. Its positive and negative DC bias voltages are specified as its parameters. Sometimes the simulation doesn't converge if there is no DC path from the output of the Op-Amp to the ground.&lt;br /&gt;

== Optocoupler ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK115.png]]&lt;br /&gt;
&lt;br /&gt;
This is a five-pin parameterized optocoupler device. Its model consists of an ideal diode device in series with an Ohmic resistance connected between the Anode (A) and Cathode (K) pins together with a bipolar junction transistor device with three accessible pins, Collector (C), Base (B) and Emitter (E). A current-controlled current source is connected between base and collector of the BJT, whose current is controlled by the current passing through the diode. The proportionality constant is twice the specified value of the current transfer ratio (ctr) parameter. &lt;br /&gt;
&lt;br /&gt;
You can change or enhance the models of the diode and BJT by adding more parameters. To do so, you have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

&lt;br /&gt;
[[File:GK113.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 4-pin parameterized photodiode device. A pair of pins, Anode (A) and Cathode (K), represent the physical terminals of the photodiode. The photodiode model connected between the anode and cathode pins consists of the parallel connection of an ideal diode, a dark current source, a noise current source, a current-controlled current source, a diode capacitance, a shunt resistance altogether with a series resistance.  &lt;br /&gt;
&lt;br /&gt;
Another pair of pins IS+ and IS- act as an ammeter that must be inserted in a control circuit. The current passing through this ammeter controls the current of the photodiode. The default proportionality constant is unity. The controlling current is typically a function of light intensity incident on the surface of the photodiode.    &lt;br /&gt;

==Piecewise Linear (PWL) Controlled Source==&lt;br /&gt;
&lt;br /&gt;
[[File:GL49.png]]&lt;br /&gt;
&lt;br /&gt;
The Piecewise Linear (PWL) Controlled Source is a single-input and single-output function generator whose output is not necessarily&lt;br /&gt;
linear for all input values. Instead, it follows an I/O relationship that is specified by the x_array and y_array coordinates. The x_array and y_array values represent vectors of coordinate points on the x and y axes, respectively. The x_array values are progressively increasing input coordinate points, and the associated y_array values represent the outputs at those points.  There may be as few as two pairs specified, or as many as memory and simulation speed allow.&lt;br /&gt;
&lt;br /&gt;
In order to fully specify outputs for values of Vin outside of the bounds of the PWL function, the PWL&lt;br /&gt;
controlled source model extends the slope found between the lowest two coordinate pairs and the highest&lt;br /&gt;
two coordinate pairs.  This has the effect of making the transfer function completely linear for Vin&lt;br /&gt;
less than x_array[0] and Vin greater than x_array[n]. It also has the potentially subtle effect of unrealistically&lt;br /&gt;
causing an output to reach a very large or small value for large inputs. You should thus keep in mind&lt;br /&gt;
that the PWL Source does not inherently provide a limiting capability.&lt;br /&gt;
&lt;br /&gt;
In order to diminish the potential for divergence of simulations when using the PWL block, a form&lt;br /&gt;
of smoothing around the x_array and y_array coordinate points is necessary.  This is due to the iterative&lt;br /&gt;
nature of the simulator and its reliance on smooth first derivatives of  transfer functions in order to&lt;br /&gt;
arrive at a matrix solution.  Consequently, the two parameters &amp;quot;input_domain&amp;quot; and &amp;quot;fraction&amp;quot; are included&lt;br /&gt;
to allow you some control over the amount and nature o the smoothing performed.&lt;br /&gt;
&lt;br /&gt;
Fraction is a switch that is either TRUE or FALSE.  When TRUE (the default setting), the simulator assumes&lt;br /&gt;
that the specified input_domain value is to be interpreted as a fractional figure.  Otherwise, it is interpreted&lt;br /&gt;
as an absolute value.  Thus, if fraction = TRUE and input_domain = 0.10, the simulator assumes that the smoothing&lt;br /&gt;
radius about each coordinate point is to be set equal to 10% of the length of either the x_array segment&lt;br /&gt;
above each coordinate point, or the x_array segment below each coordinate point. The specific segment&lt;br /&gt;
length chosen will be the smallest of these two for each coordinate point.&lt;br /&gt;
&lt;br /&gt;
If fraction = FALSE and input_domain = 0.10, then the simulator will begin smoothing the transfer function at 0.10&lt;br /&gt;
volts (or amperes) below each x_array coordinate and will continue the smoothing process for another 0.10&lt;br /&gt;
volts (or amperes) above each x_array coordinate point.&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Programmable Unijunction Transistor (PUT) device with three pins: Base 1 (B1), Base 2 (B2) and Emitter (E). It is biased with a positive voltage between the two bases. This device has a unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. It exhibits a negative resistance characteristic and so it can be employed as an oscillator. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively. To change these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.    &lt;br /&gt;

==Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK119.png]]&lt;br /&gt;
&lt;br /&gt;
Resistors are passive devices that dissipate power. Their resistance value varies depending on how much power they can dissipate and is measured&lt;br /&gt;
in Ohms.  The transient, DC and AC behaviors of a resistor are all described by the same equation:&lt;br /&gt;
&lt;br /&gt;
v = R * i&lt;br /&gt;
&lt;br /&gt;
where v is the voltage across the resistor, i is the current passing through the resistor, and R is the resistance. The value of R must be nonzero. &lt;br /&gt;
&lt;br /&gt;
All resistor names must begin with R.&lt;br /&gt;

Example: &lt;br /&gt;
&lt;br /&gt;
R1 1 2 1k&lt;br /&gt;
&lt;br /&gt;
[[RF.Spice A/D]] provides three types of resistor: Simple, User-Defined (Real Resistor) and Semiconductor. The resistance of the simple resistor is a single value expressed in Ohms. You can also set the Monte Carlo tolerance for this resistor.&lt;br /&gt;
&lt;br /&gt;
==Schottky Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK80.png]]&lt;br /&gt;
&lt;br /&gt;
The Schottky diode has the same model as the generic diode with a nonzero transit time (tt), a nonzero junction capacitance (cjo) and a typically larger saturation current (is), a lower junction potential (vj) and a smaller grading coefficient (m).   &lt;br /&gt;
&lt;br /&gt;
==Semiconducting Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK83.png]]&lt;br /&gt;
&lt;br /&gt;
This is the more general form of the Capacitor model and allows for the calculation of the actual capacitance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
CXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;IC=VAL&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it defines the capacitance. If MNAME is specified, then the capacitance is calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. Either VALUE or MNAME, LENGTH, and WIDTH may be specified, but not both sets. The optional initial condition &amp;quot;IC&amp;quot; is the initial voltage across the capacitor for transient simulations.&lt;br /&gt;
&lt;br /&gt;
The capacitance is computed as:&lt;br /&gt;
&lt;br /&gt;
CAP = CJ * (LENGTH - NARROW) * (WIDTH - NARROW)+ 2 * CJSW * (LENGTH + WIDTH - 2NARROW) * CAP&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the capacitor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit CJ, CJSW, NARROW, DEFW, and CAP.&lt;br /&gt;

&lt;br /&gt;
This is the more general form of the resistor model and allows for the modeling of temperature effects and for the calculation of the actual resistance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
RXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;TEMP=T&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it overrides the geometric information and defines the resistance. If MNAME is specified, then the resistance may be calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. The (optional) TEMP value is the temperature at which this device is to operate, and overrides the temperature specification in the SPICE Options Dialog. &lt;br /&gt;
&lt;br /&gt;
The resistance is computed as:&lt;br /&gt;
&lt;br /&gt;
R(T0) = (RSH) * [(L - NARROW) / (W - NARROW)] * RES&lt;br /&gt;
&lt;br /&gt;
R(T) = R(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the resistor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit TC1, TC2, RSH, RES, etc.&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Silicon-Controlled Rectifier (SCR) device with three pins: Anode (A), Cathode (K) and Gate (G). It is a unidirectional device which can conduct current only in one direction. The SCR can be triggered only by a positive current going into its gate.

== Triac Thyristor ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK110.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin bidirectional thyristor device that conducts current in either direction when triggered. A thyristor is analogous to a relay in that a small voltage and current can control a much larger voltage and current. The triac has two anode pins termed Main Terminal 1 (MT1) and Main Terminal 2 (MT2) and a Gate (G) pin. In order to create a triggering current for a triac, either a positive or negative voltage can be applied to the gate. Once triggered, the thyristor continues to conduct, even if the gate current ceases, until the main current drops below a certain level called the holding current. The device's model involves two NPN BJT transistors and two PNP BJT transistors. The forward beta parameters of the NPN and PNP transistors are set equal to 20 and 5, respectively. To changes these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.&lt;br /&gt;

==Uniform RC Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G23.png]]&lt;br /&gt;
&lt;br /&gt;
The standard parameters are L, and N.  They are described below:&lt;br /&gt;
&lt;br /&gt;
Two of the nodes are the element nodes connected by the RC line.  The third is the node to which the capacitances&lt;br /&gt;
are connected.  L is the length of the RC line in meters.  N is the number of lumped segments to use in&lt;br /&gt;
modeling the RC line.&lt;br /&gt;
&lt;br /&gt;
This device is derived from a model proposed by Gertzberrg.  It expands the URC line into a network of&lt;br /&gt;
lumped RC segments with internally generated nodes.  These segments increase toward the middle of the&lt;br /&gt;
URC line in a geometric progression with K as the proportionality constant.&lt;br /&gt;
&lt;br /&gt;
The URC line is made up entirely of resistor and capacitor segments, unless the ISPERL parameter has a&lt;br /&gt;
non-zero value.  In this case, capacitors are replaced by reverse biased diodes with an equivalent zero-bias&lt;br /&gt;
junction capacitance, a saturation current of ISPERL amps per meter of transmission line, and optional&lt;br /&gt;
series resistance of RSPERL ohms per meter. &lt;br /&gt;

==Voltage-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G19.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Voltage-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Voltmeter or controlling voltage nodes, as well as the turn-on and turn-off voltages in Volts and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the rest of [[parameters]]. When the voltage across the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the voltage across the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Voltage Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17A.png]]&lt;br /&gt;
&lt;br /&gt;
A voltage source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a voltage source is its initial transient value. For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset voltage. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==XSpice Devices and their models==&lt;br /&gt;
&lt;br /&gt;
XSpice devices have the following form:&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 4pt  0pt  1px  0pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;

&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
e.g., A2 1  2  transfer_function&lt;br /&gt;
&lt;br /&gt;
Note that XSpice devices must start with the &amp;amp;quot;A&amp;amp;quot; designation, much as a resistor starts with&lt;br /&gt;
an &amp;amp;quot;R&amp;amp;quot;.  Some devices will have grouped (or vector) pins and are designated by being placed&lt;br /&gt;
inside square brackets.  In the example shown below, the 1 and 2 pins are grouped.  Pin 3 is not.  &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  0pt ; text-indent: 36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
A1 [1   2]  3 summer &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Some models will have voltage differential pairs of pins and will be denoted by a %vd( ).  In the following&lt;br /&gt;
example pins 1 and 4 are differential pairs, as well as pins 2 and 3.  Differential pairs must go between&lt;br /&gt;
parentheses (). &lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  0pt ; text-indent: 36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
A1 %vd(1   4)   %vd(2   3)  triangle &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Refer to individual devices for more information.&lt;br /&gt;
&lt;br /&gt;
Each XSpice device will also have a model associated with it.  Each model will have the following form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
.model &amp;amp;lt;model_name&amp;amp;gt; &amp;amp;lt;model_identifier&amp;amp;gt; {&amp;amp;lt;pname1 = pval1&amp;amp;gt;} {&amp;amp;lt;pname2 = pval2&amp;amp;gt;} &lt;br /&gt;
...&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
e.g., .model transfer_function s_xfer  in_offset = 0.0  gain = 1.0&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Model_name refers to the name given in the device line.  Model_identifier is an internal designation and&lt;br /&gt;
must be of an existing designation  Refer to each device's example for the correct designation. &lt;br /&gt;
&lt;br /&gt;
Parameter values are optional.  If they aren't specified, then the default will be used.  Some devices&lt;br /&gt;
have parameters that require a value and must be specified.  Refer to individual devices for any required parameters.&lt;br /&gt;
&lt;br /&gt;
==Zener Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:G10.png]]&lt;br /&gt;
&lt;br /&gt;
The Zener Diode models the DC characteristics of most zeners. Since most data sheets for zener diodes do&lt;br /&gt;
not give detailed characteristics in the forward region, only a single point defines the forward characteristicThe&lt;br /&gt;
saturation current refers to the relatively constant reverse current that is produced when the voltage&lt;br /&gt;
across the zener is negative, but breakdown has not been reached.  The reverse leakage current determines&lt;br /&gt;
the slight increase in reverse current as the voltage across the zener becomes more negative.  It is modeled&lt;br /&gt;
as a resistance parallel to the zener with value v_breakdown / i_rev.&lt;br /&gt;
&lt;br /&gt;
Note that the limt_switch parameter engages an internal limiting function for the zener.  This can, in&lt;br /&gt;
some cases, prevent the simulator from converging to an unrealistic solution if the voltage across or&lt;br /&gt;
current into the device is excessive.  If use of this feature fails to yield acceptable results, the convlimit&lt;br /&gt;
option should be tried (add the following statement to the SPICE input deck:  .options convlimit)&lt;br /&gt;
&lt;br /&gt;
Model Identifier: zener&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;

==Analog-to-Digital Converter (ADC) Bridge==&lt;br /&gt;
[[File:GK42.png]]&lt;br /&gt;
&lt;br /&gt;
The ADC Bridge takes an analog value from an analog node and may be in the form of a voltage or current.&lt;br /&gt;
If the input is less than or equal to &amp;amp;quot;in_low&amp;amp;quot;, then a digital &amp;amp;quot;0&amp;amp;quot; is generated. If&lt;br /&gt;
the input is greater than or equal to &amp;amp;quot;in_high&amp;amp;quot;, a digital &amp;amp;quot;1&amp;amp;quot; is generated. Otherwise,&lt;br /&gt;
a digital &amp;amp;quot;UNKNOWN&amp;amp;quot; is the output value. Unlike the DAC Bridge, ramping or delay is not applicable.&lt;br /&gt;
Rather, the continuous ramping of the input provides for any associated delays in the digitized signal.&lt;br /&gt;
&lt;br /&gt;
This model also posts an input load value based on the parameter input_load.&lt;br /&gt;

==Bipolar Junction Transistor (BJT)==&lt;br /&gt;
[[File:G11.png]]&lt;br /&gt;
&lt;br /&gt;
The BJT is an active device which has up to 4 pins.  The three standard pins are base, emitter, and collector.  These are given in the default symbol.  The substrate, which is grounded by default, is the fourth pin.  To use the BJT with the substrate, create a new 4-pin BJT using the Device Editor and Symbol Editor.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|AREA||area factor (optional) (If not specified, the default value is 1.0.)&lt;br /&gt;
|-&lt;br /&gt;
|OFF||initial condition for the DC analysis (optional)&lt;br /&gt;
|-&lt;br /&gt;
|IC||initial condition (optional) (Used when a transient analysis is desired, which starts from other than the quiescent operating point.)&lt;br /&gt;
|-&lt;br /&gt;
|T||operating temperature of the device (optional)&lt;br /&gt;
|-&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Area factor scales the model parameters RE and RC.  IC VBE is the initial voltage from base emitter. IC VCE is the initial voltage from collector to emitter.  TEMP is the overriding temperature. These parameters are based on the Gummel and Poon integral-charge model.  If these parameters are not specified, then it will reduce to the simpler Ebers-Moll model. &lt;br /&gt;
&lt;br /&gt;
The process model is mandatory for the BJT.  Descriptions of the process model parameters are given in the following table:&lt;br /&gt;

==Branchline Hybrid Coupler==&lt;br /&gt;
[[File:G81.png]]&lt;br /&gt;
&lt;br /&gt;
This is an eight-pin, four-port device that models a branchline quadrature hybrid coupler. If Port 1 acts as an input port, the output power is equally split between Ports 2 and 3. Port 2 has 90&amp;amp;deg; phase shift with respect to the input, while Port 3 is in-phase with respect to the input. Port 4 acts as an isolated port. Since the branchline hybrid has a symmetric structure, any port can serve as the input port. You have to specify the center frequency of the device in GHz.  &lt;br /&gt;

==Capacitance Meter==&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Capacitance Meter measures the total capacitance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total capacitance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense a capacitance value and alter their behavior based upon it.&lt;br /&gt;

==Capacitor==&lt;br /&gt;
[[File:GK120.png]]&lt;br /&gt;
&lt;br /&gt;
Capacitors are used to store electrical energy.  They can filter or remove AC signals or block DC current without disrupting AC signals. A capacitor's ability to store energy is termed capacitance and is measured in Farads, with values from pF to mF. The only time current flows through a capacitor is when the charge is collected on, or is removed from, its parallel plates. This means that the voltage across the capacitor is changing, which doesn't conform to DC analysis. In a physical circuit, there is a transition stage during which capacitors charge up to their final values. The result is the same as if these capacitors did not exist and the connections to them were left dangling. In other words, in a (steady-state) DC analysis, a capacitor behaves like an open circuit. Therefore, it is important that no section of the circuit is isolated from the capacitors. Every circuit node needs some path for DC current to the ground.&lt;br /&gt;
&lt;br /&gt;
A capacitor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
i(t) = C * (dv(t)/dt)&lt;br /&gt;
&lt;br /&gt;
Its initial voltage is only important when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked.&lt;br /&gt;
&lt;br /&gt;
An capacitor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
i = j ω * C * v &lt;br /&gt;
&lt;br /&gt;
All capacitor names must begin with C. &lt;br /&gt;

[[RF.Spice A/D]] provides three types of capacitors: simple, user-defined (or real) and semiconductor. The standard capacitor parameters are N+, N-, VALUE, and IC. In a simple capacitor, VALUE must&lt;br /&gt;
be specified for the capacitance in Farads. IC is the (optional) initial condition for the capacitor voltage.&lt;br /&gt;

==Center-Tapped Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK97.png]]&lt;br /&gt;
&lt;br /&gt;
This five-pin three-port device models a center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;
&lt;br /&gt;
To change the value of H/B arrays, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

==Controlled Limiter Block==&lt;br /&gt;
&lt;br /&gt;
[[File:G35.png]]&lt;br /&gt;
&lt;br /&gt;
The Controlled Limiter is a single-input, single-output block similar to the Gain Block. However, the output of the Controlled Limiter function is restricted to the range specified by the output lower and upper limits. This model operates in DC, AC and Transient analysis modes. Note that the limit range is the value below the Upper Limit Control input signal (CNTL_UPPER) and above the Lower Limit Control input signal (CNTL_LOWER) at which smoothing of the output signal begins. A minimum positive value of voltage difference must exist between the CNTL_UPPER and CNTL_LOWER inputs at all times. The main difference between the Controlled Limiter Block and the Limiter Block is that the former's limits are set by input control voltages, while the latter's limits are set as numerical parameters.     &lt;br /&gt;
&lt;br /&gt;
Also note that the Controlled Limiter function examines the input values of CNTL_UPPER and CNTL_LOWER to make sure that they are spaced far enough apart to guarantee the existence of a linear range between them. The range is calculated as the difference between (cntl_upper - upper_delta - limit_range) and (cntl_lower&lt;br /&gt;
+ lower_delta + limit_range) and must be greater than or equal to zero.  When the limit_range is specified as a fractional value, the limit_range used in the above is taken as the calculated fraction of the difference between cntl_upper and cntl_lower. Still, the potential exists for too great a limit_range value to be specified for proper operation, in which case the model will return an error message.&lt;br /&gt;

This is an eight-terminal function generator with a single pulse output. The pulse width is controlled by an input voltage.

==Current Limiter Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GL43.png]]&lt;br /&gt;
&lt;br /&gt;
The Current Limiter Block models the behavior of an operational amplifier or comparator device at a high level of abstraction. All of its pins act as inputs; three of the four also act as outputs. The model takes as input a voltage value from the “in” connector. It then applies an offset and a gain, and derives from it an equivalent internal voltage (veq), which it limits to fall between pos pwr and neg pwr. If veq is greater than the output voltage seen on the “out” connector, a sourcing current will flow from the output pin. Conversely, if the voltage is less than vout, a sinking current will flow into the output pin. Depending on the polarity of the current flow, either a sourcing or a sinking resistance value (r_out_source, r_out_sink) is applied to govern the vout/i_out relationship. The chosen resistance will continue to control the output current until it reaches a maximum value specified by either i_limit_source or i_limit_sink. The latter mimics the current limiting behavior of many operational amplifier output stages. During all operation, the output current is reflected either in the pos_pwr connector current or the neg_pwr current, depending on the polarity of i_out. Thus, realistic power consumption as seen in the supply rails is included in the model. The user-specified smoothing parameters relate to model operation as follows: v_pwr_range controls the voltage below vpos_pwr and above vneg_pwr inputs beyond which veq [= gain * (vin + voffset)] is smoothed; i_source_range specifies the current below i_limit_source at which smoothing begins, as well as specifying the current increment above i_out=0.0 at&lt;br /&gt;
which i_pos_pwr begins to transition to zero; i_sink_range serves the same purpose with respect to i_limit_sink and i_neg_pwr that i_source_range serves for i_limit_source &amp;amp; i_pos_pwr; r_out_domain specifies the incremental value above and below (veq-vout)=0.0 at which r_out will be set to r_out_source and r_out_sink, respectively. For values of (veq-vout) less than r_out_domain and greater than -r_out_domain, r_out is interpolated smoothly between r_out_source &amp;amp; r_out_sink.&lt;br /&gt;

==Current Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17B.png]]&lt;br /&gt;
&lt;br /&gt;
Current source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a current source is its initial transient value.  For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset current. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==Current-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G20.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Current-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the turn-on and turn-off currents in Amperes and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the rest of [[parameters]]. When the current through the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the current through the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==D Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G52.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type flip-flop is a one-bit, edge-triggered storage element which stores data whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). In addition, there are asynchronous set and reset signals, which are independent of the clock. When SET = RESET = 0, the data on the D line is transferred to the output Q on the rising edge of the clock. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

==D Latch==&lt;br /&gt;
&lt;br /&gt;
[[File:G54.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type latch is a one-bit, level-sensitive storage element which outputs the value on the data (D) line whenever the enable (EN) input line is 1 (high). The value on the data line is stored, i.e., held on the output (Q) line whenever the enable (EN) line is 0 (low). In addition, there are set and reset signals, which are independent of the enable line. When SET = RESET = 0, the data on the D line is transferred to the output Q whenever EN = 1. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

==Darlington Pair==&lt;br /&gt;
&lt;br /&gt;
[[File:GK108.png]]&lt;br /&gt;
&lt;br /&gt;
A Darlington pair is a three-pin device that consists of two interconnected BJT transistors of the same type. The collectors of two transistors are connected together to provide the &amp;quot;Collector&amp;quot; pin of the pair. The base of the first BJT acts the &amp;quot;Base&amp;quot; pin of the pair. The emitter of the first BJT is internally connected to the base of the second BJT. The emitter of the second BJT acts as the &amp;quot;Emitter&amp;quot; pin of the pair. There are two types of Darlington pair: NPN and PNP. The parameterized generic Darlington pair also contains a diode connected between the collector and emitter pin as well as two base-emitter resistors, one across each BJT.     &lt;br /&gt;

==Differentiator Block==&lt;br /&gt;
&lt;br /&gt;
[[File:G31.png]]&lt;br /&gt;
&lt;br /&gt;
The Differentiator Block approximates the time derivative of an input signal by calculating the incremental&lt;br /&gt;
slope of that signal since the previous time point. Gain and output offset parameters are also included&lt;br /&gt;
to allow for tailoring of the required signal. Output upper and lower limits are also included to prevent&lt;br /&gt;
convergence erros resulting from excessively large output values. The incremental value of output below&lt;br /&gt;
the output_upper_limit and above the output_lower_limit at which smoothing begins is specified via the&lt;br /&gt;
limit_range parameter.  In AC analysis, the value returned is equal to the radian frequency of analysis&lt;br /&gt;
multiplied by the gain.&lt;br /&gt;

== Discrete Convolution Block ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK20.png]]&lt;br /&gt;
&lt;br /&gt;
These blocks perform an N-point discrete convolution of their input signals. Both of the input signals x(t) and h(t) are sampled at the specified sampling period. The samples of x(t) are then shifted in time for the convolution. The output signal is a pulse train of the same period with the specified duty cycle. The input signal of these block can be either continuous-time signals or pulse trains of the specified period. &lt;br /&gt;

== Discrete Fourier Transform (DFT) Block ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK19.png]]&lt;br /&gt;
&lt;br /&gt;
These blocks perform an M-point discrete Fourier transform (DFT) of their input signal and then sample each period of the Fourier transform N times in the frequency domain. The output signals are two finite sequence pulse trains representing the cosine and sine DFT transforms. The input signal of these block can be either a continuous-time signal or a pulse train of the specified period. &lt;br /&gt;
&lt;br /&gt;
There are ten DFT blocks for M = 5, 6, 7, 8, 9, 10, 12, 16, 32, 64. In each case, the total duration of the transform window is MT, where T is the sampling period. By default, the frequency domain sampling starts at t = MT and takes place over one spectral period equal to f&amp;lt;sub&amp;gt;s&amp;lt;/sub&amp;gt; = 1/T. You can change the sampling start time by &amp;quot;n_delay&amp;quot; temporal periods. n_delay = 0 by default, but it can be either positive or negative. You can also extend spectral sampling to more than one spectral period by increasing the value of the parameter &amp;quot;n_dur&amp;quot;, which has a default value of 1.       &lt;br /&gt;

&lt;br /&gt;
There are ten DTFT blocks for N = 5, 6, 7, 8, 9, 10, 12, 16, 32, 64. In each case, the total duration of the transform window is NT, where T is the sampling period.  &lt;br /&gt;

==Divider Block==&lt;br /&gt;
&lt;br /&gt;
[[File:G30.png]]&lt;br /&gt;
&lt;br /&gt;
The Divider Block has two inputs. Each of the numerator and denominator inputs is added to its respective offset and then multiplied by its respective input gain (with default values of 1). Next, the loaded numerator signal is divided by the loaded denominator signal. The result is multiplied by the output gain and then added to the output offset. To avoid division by zero, the divider function sets the denominator signal greater than zero through the lower limit parameter. This limit is approached through a quadratic smoothing function, the domain of which may be specified as a fraction of the lower limit value or as an absolute value. The divider function operates in DC, AC, and Transient analysis modes. In AC analysis, however, it is important to remember that results are invalid unless the denominator input is a DC voltage.  &lt;br /&gt;

==Doubly Center-Tapped Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK98.png]]&lt;br /&gt;
&lt;br /&gt;
This six-pin four-port device models a doubly center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;

==Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK95.png]]&lt;br /&gt;
&lt;br /&gt;
This four-pin two-port device models a physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;
&lt;br /&gt;
To change the value of H/B arrays, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

==Frequency Meter==&lt;br /&gt;
[[File:G114.png]]&lt;br /&gt;
&lt;br /&gt;
The Frequency Meter is a four-pin shunt device that is connected in parallel with an AC source just like a voltmeter and measures the operating frequency of the AC circuit. The input pins are connected across the AC source. The voltage across the output pins is equal to the frequency of the source in Hertz within a scale factor SF. Note that the Frequency Meter is designed to work with a single-tone AC source of unit amplitude. If the amplitude of the source is not one, multiply the SF parameter by the non-unit source amplitude value. The output voltage of the Frequency Meter can be used in conjunction with linear or nonlinear dependent sources to model frequency-dependent quantities.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Model Identifier: fmeter&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&amp;lt;math&amp;gt; H(s) = \frac{N(s)}{D(s)} = \frac{ \sum_{m=0}^{M} b_m s^m  }{ \sum_{n=0}^{N} a_n s^n } &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
subject to the requirement N &amp;amp;ge; M and a&amp;lt;sub&amp;gt;N&amp;lt;/sub&amp;gt; = 1. To access the parameters of this block, you have to click the {{key|Edit Model...}} button of its property dialog. &lt;br /&gt;
&lt;br /&gt;
The functionality of this block, which is native to [[RF.Spice A/D]], is very similar to the s-domain transfer function block, which is an XPSICE process model. This block does not have a denormalization frequency parameter. Therefore, at frequencies other than the unit frequency, the transfer function must be explicitly scaled. This block can be used in conjunction with both transient and AC frequency sweep tests.   &lt;br /&gt;

==Hysteresis Block (XSPICE)==&lt;br /&gt;

&lt;br /&gt;
The Hysteresis block is a simple buffer stage that provides hysteresis of the output with respect to the&lt;br /&gt;
input.  The in_low and in_high parameter values.  The output values are limited to out_lower_limit and&lt;br /&gt;
out_upper_limit.  The value of \93hyst\94 is added to the in_low and in_high points in order to specify the&lt;br /&gt;
points at which the slope of the hysteresis function would normally change abruptly as the input transitions&lt;br /&gt;
from a low to a high value.  Likewise, the value of \93hyst\94 is subtracted from the in_high and in_low values&lt;br /&gt;
in order to specify the points at which the slope of the hysteresis function would normally change abruptly&lt;br /&gt;
as the input transitions from a high to a low value.  In fact, the slope of the hysteresis function is&lt;br /&gt;
never allowed to change abruptly but is smoothly varied whenever the input_dowmain smoothing parameter&lt;br /&gt;
is set greater than zero.&lt;br /&gt;

The ideal transformer is a four-pin two-port device with the following relationship between the voltages and currents at its primary and secondary ports:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_S} = - \frac{i_S}{i_P} = \frac{N_P}{N_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; are the primary voltage, current and number of turns, respectively, and v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; are the secondary voltage, current and number of turns, respectively. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary turns ratio. Note that the ideal transformer model is defined based on controlled sources and does not involve any magnetic physical parameters as opposed to mutual inductors or ferrite core transformer.&lt;br /&gt;
&lt;br /&gt;
==Inductance Meter==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductance Meter measures the total inductance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total inductance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense an inductance value and alter their behavior based upon it. Care must be exercised when connecting an Inductance Meter to the inductors of a circuit. This is due to the fact that inductors are treated by SPICE as current sources. This can cause a problem when an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. &lt;br /&gt;

==Inductive Coupler Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GK99.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductive Coupler Block couples any two existing inductors. This block doesn't have any pins because it doesn't actually represent inductors, only the coupling between them. This is useful if you want to&lt;br /&gt;
couple two inductors that are in different parts of the circuit, or if you want to couple more than two inductors together. In the latter case, use more than one of these, with each one coupling a pair of inductors.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are Inductor1, Inductor2, and k. Inductor1 is the name of first inductor, Inductor2 is the name of the second inductor, and k is the coefficient of coupling, 0 &amp;amp;lt; k &amp;amp;le; 1.&lt;br /&gt;
&lt;br /&gt;
==Inductive Coupling (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G41.png]]&lt;br /&gt;
&lt;br /&gt;
This function is a conceptual model which is used as a building block to create a wide variety of inductive and magnetic circuit models. This function is normally used in&lt;br /&gt;
conjunction with the “core” model, but it can also be used with resistors, hysteresis blocks, etc. to build up systems which mock the behavior of linear and nonlinear components.&lt;br /&gt;
The lcouple takes as an input (on the “l” port) a current. This current value is multiplied by the num_turns value, N, to produce an output value (a voltage value which appears on the&lt;br /&gt;
mmf_out port). The mmf_out acts similar to a magnetomotive force in a magnetic circuit;&lt;br /&gt;
when the lcouple is connected to the “core” model, or to some other resistive device, a current will flow. This current value (which is modulated by whatever the lcouple is&lt;br /&gt;
connected to) is then used by the lcouple to calculate a voltage “seen” at the “l” port. The voltage is a function of the derivative with respect to time of the current value seen at mmf_out.&lt;br /&gt;
&lt;br /&gt;
The most common use for lcouple will be as a building block in the construction of transformer models. To create a transformer with a single input and a single output, you&lt;br /&gt;
would require two lcouple models plus one “core” model. &lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
A1 (1 0) (2 3) lcouple1&lt;br /&gt;
&lt;br /&gt;
.model lcouple1 lcouple ( num_turns = 10 )&lt;br /&gt;

==Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK121.png]]&lt;br /&gt;
&lt;br /&gt;
Inductors are used to store magnetic energy. An inductor's ability to counteract current changes passing through it is called its inductance (L), which is&lt;br /&gt;
measured in Henrys. In a (steady-state) DC analysis, the inductor acts like a short circuit. It is indeed treated as a current source, which can be problematic if an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. The resistor may be of negligible value or one that accounts for the coil resistance of the inductor. In AC and transient analyses, the inductor develops a voltage across it in response to the changing magnetic&lt;br /&gt;
flux within its coil. &lt;br /&gt;
&lt;br /&gt;
An inductor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
v(t) = L*(di(t)/dt) &lt;br /&gt;
&lt;br /&gt;
The inductor's initial condition is optional. It is the initial value of the inductor current in Amperes that flows from node N+ through the inductor to node N-. The only time that the initial current matters is when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked. &lt;br /&gt;
&lt;br /&gt;
An inductor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
v = j &amp;amp;omega; * L * i&lt;br /&gt;
&lt;br /&gt;
All inductor names must begin with L.&lt;br /&gt;

==Inductor with Ferrite Core==&lt;br /&gt;
&lt;br /&gt;
[[File:GK94.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device models a physical inductor with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. Unlike the standard inductor device, you do not specify an inductance value for the inductor with ferrite core. Rather, you specify physical parameters like cross sectional area, core length and number of turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;

== Insulated Gate Bipolar Transistor (IGBT)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK111.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Insulated Gate Bipolar Transistor (IGBT) device with three pins: Collector(C), Gate (G), and Emitter (E). It is primarily used as a fast electronic switch. The IGBT combines the simple gate-drive characteristics of MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors. The device's model consists of an isolated gate FET for the control input, and a PNP bipolar power transistor as a switch.

==Junction Field Effect Transistor (JFET)==&lt;br /&gt;
&lt;br /&gt;
[[File:G12.png]]&lt;br /&gt;
&lt;br /&gt;
The JFET is the simplest transistor device and has three pins: gate, drain and source. The JFET defaults are based on the Shichman and Hodges FET model. This is a square-law device because of the expression relating the drain current to the gate-to-source voltage: &lt;br /&gt;
Idrain=*(VGS-Vthreshold)2.  In real JFETs, near the saturation point, the drain currents vary with the drain voltages. This can be modeled by the following formula:  Idrain=*(VGS-VTO)2*(1+*VDS), which yields an increasing&lt;br /&gt;
drain current for increasing values of VDS.&lt;br /&gt;
&lt;br /&gt;
The gate-to-source and gate-to-drain junctions each have a nonlinear capacitor.  The zero-bias capacitance value is selected for each junction.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

&lt;br /&gt;
The CCCS is a current source whose current is directly proportional to the current across a controlling Ammeter or a voltage source. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the current gain, which has a default value of one. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the current gain.   &lt;br /&gt;

==Lossless Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G21.png]]&lt;br /&gt;
&lt;br /&gt;
The lossless transmission line is a four-pin two-port device that models only one propagating mode of an ideal transmission line.  When using this SPICE model, should all four nodes of the actual circuit be distinct, two modes may be activated, and this device would be insufficient for that purpose. To circumvent this potential problem, two transmission line devices would be required. Due to the implementation details, you may produce more accurate simulation results with a lossy transmission line device with zero loss.&lt;br /&gt;
&lt;br /&gt;
Optional initial condition parameters are the voltage and current at each of the transmission line ports.&lt;br /&gt;
&lt;br /&gt;

The RLC (uniform transmission line with series loss only), RC (uniform RC line), LC (lossless transmission&lt;br /&gt;
line), and RG (distributed series resistance and parallel conductance only) lines have been implemented. &lt;br /&gt;
The length (LEN) must be given.  COMPACTREL and COMPACTABS control the compaction of past history values&lt;br /&gt;
used in convolution.  Larger values for these lower accuracy but improve speed.  These are used with the&lt;br /&gt;
TRYTOCOMPACT option. &amp;lt;/P&amp;gt;&lt;br /&gt;

==Magnetic Core (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G42.png]]&lt;br /&gt;
&lt;br /&gt;
This device is used as a building block to create a wide variety of inductive and magnetic circuit models. It is almost always to be used in conjunction with the &amp;quot;lcouple&amp;quot; model to build up systems which simulate the behavior of linear and nonlinear magnetic components. There are two fundamental modes of operation for the core model. These are the &amp;quot;PWL&amp;quot; mode (which is the default and most&lt;br /&gt;
likely to be of use to you) and the &amp;quot;Hysteresis&amp;quot; mode.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;PWL Mode (mode = 1)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the PWL mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf) value. This value is divided by the total effective length of the core to produce a value for the Magnetic Field Intensity, H, which is then used to find the corresponding Flux Density, B, using the piecewise linear relationship described by you in the H_array / B_array coordinate pairs. B is then multiplied by the cross-sectional area of the core to find the Flux value, which is output as a current. The pertinent mathematical equations are:&lt;br /&gt;
&lt;br /&gt;
H = mmf / L, where L = Length (in apmere-turns/meter)&lt;br /&gt;
&lt;br /&gt;
B = f(H)&lt;br /&gt;
&lt;br /&gt;
&amp;amp;Phi; = B * A, where A = Area&lt;br /&gt;
&lt;br /&gt;
The B value is derived from a piecewise linear transfer function described to the model by the H_array and B_array coordinate pairs.  This transfer function does not include hysteretic effects; for that, you would need to substitute a HYST model for the core. The magnetic flux value &amp;amp;Phi; in turn is used by the &amp;quot;lcouple&amp;quot;&lt;br /&gt;
code model to obtain a value for the voltage reflected back across its terminals to the driving electrical circuit.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Hysteresis Mode (mode = 2)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the Hysteresis mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf)&lt;br /&gt;
value.  This value is used as input to the equivalent of a hysteresis code model block.  The parameters&lt;br /&gt;
defining the input low and high values, the output low and high values, and the amount of hysteresis are&lt;br /&gt;
as in that model. The output from this mode, as in PWL mode, is a current value which is seen across the magnetic core port.&lt;br /&gt;
&lt;br /&gt;
One final note to be made about the two core models is that certain parameters are specific to one or the other.  In particular, the in_low, in_high, out_lower_limit, out_upper_limit, and hysteresis parameters are not available in PWL mode. Likewise, the H_array, B_array, area, ad length values are unavailable&lt;br /&gt;
in Hysteresis mode.  The input_domain and fraction parameters are common to both modes (though their behavior is somewhat different; for explanation of the input_domain and fraction values for the Hysteresis mode, please refer to the Hysteresis Block discussion.&lt;br /&gt;

&lt;br /&gt;
The marker serves several purposes:&lt;br /&gt;
&lt;br /&gt;
* It can appear as a default plot in simulations if the &amp;amp;quot;Voltage Probe&amp;amp;quot; box is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to set the initial voltage or voltage guess at the node it is connected to.&lt;br /&gt;
&lt;br /&gt;
* It can be used as a port for a subcircuit when you choose the checkbox labeled &amp;quot;Use as Subcircuit Port&amp;quot; is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to explicitly set a node number in place of the arbitrarily assigned node number by the program. In this case, make sure the &amp;amp;quot;Set Node Index&amp;amp;quot; box is checked.  Otherwise, it will act as just a voltage probe.&lt;br /&gt;
&lt;br /&gt;
* It can be used to connect different parts of a circuit in place of wires. To use markers as virtual connectors, place them at points where wires would otherwise connect. Then set the Part Title of the two (or more) markers to the same name, and they will act as a single circuit node.&lt;br /&gt;

==MESFET==&lt;br /&gt;
&lt;br /&gt;
[[File:G14.png]]&lt;br /&gt;
&lt;br /&gt;
The MESFET is a Schottky-barrier gate FET with six times greater electron mobility than silicon.  MESFETs are important devices for creating high frequency circuits. They function by creating a potential barrier between the gate and the channel when the metal gate&lt;br /&gt;
contacts the gallium-arsenide substrate. Electron velocity saturates for fields approximately ten times lower than with silicon.  The Curtice model includes linear and saturated operation.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

&lt;br /&gt;
The MOSFET is an active device that has up to 4 pins.  The three standard pins are gate, drain, and source.  These are given in the default symbol.  The bulk node, which is grounded by default, is the fourth pin.  The MOSFET with the bulk is named mos_n_lvl1_4 (the lvl1 is for level 1, the n for nmos, and the 4 for 4 pins.)&lt;br /&gt;
&lt;br /&gt;
The standard [[parameters]] are L, W, AD, AS, PD, PS, NRD, NRS, OFF, IC, and T.  They are described below:&lt;br /&gt;

There are five different default models: square-law I-V characteristic, analytical, semi-empirical, and BSIM and BSIM2 (Berkeley Short-channel IGFET Model), which include second-order effects such as channel-length&lt;br /&gt;
modulation, subthreshold conduction, scattering-limited velocity saturation, small-size effects, and charge-controlled capacitance.  The process parameter LEVEL specifies which of the models is chosen as indicated below:&lt;br /&gt;

[[File:GK100.png]]&lt;br /&gt;
&lt;br /&gt;
The mutual inductors device is a pair of inductors that are coupled to each other.  L1 and L2 are the names of two inductors. You have to specify the inductance of inductor L1, the inductance of inductor L2, the initial current through each, and the coupling coefficient k, 0 &amp;amp;le; k &amp;amp;le; 1. The mutual inductance M expressed in units of H can be calculated using the following definition:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; k = \frac{M}{\sqrt{L_1 L_2}} &amp;lt;/math&amp;gt;&lt;br /&gt;

==Non-Ideal Current Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK104.png]]&lt;br /&gt;
&lt;br /&gt;
This 8-pin device models a non-ideal lossy current transformer. Its model consists of an ideal transformer with more secondary turns than primary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. on each side of the internal ideal transformer, there is a series leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, followed by a shunt winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a series winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, which connects to the exterior positive pin on that side. The inter-winding resistance R&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the negative pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance. &lt;br /&gt;

&lt;br /&gt;
This 2-pin device is a basic simplified model of a diode as a rectifier or switch. When forward-biased, it acts as a low-valued voltage source. When reverse-biased, it acts as an open circuit until the reverse voltage exceeds the specified breakdown voltage. Then it acts as a high-valued voltage source of the reverse polarity. &lt;br /&gt;

&lt;br /&gt;
This 8-pin device models a non-ideal lossy voltage transformer. Its model consists of an ideal transformer with more primary turns than secondary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. There are series combinations of a winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; on the primary and secondary sides. These are connected between the positive interior and exterior pins on each side. There are also two shunt branches at the inputs of the primary and secondary sides (connected between the positive and negative exterior pins), each consisting of a distributed turn-to-turn winding resistance RDC&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; in series with a distributed turn-to-turn winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;. The inter-winding capacitance CWW&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the positive pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance.  &lt;br /&gt;

==Nonlinear Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK89.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear capacitor model allows the capacitor to be described by an arbitrary relationship between the capacitor's charge Q and the voltage V across the capacitor. In other words, Q = f(V). The nonlinear capacitance is then defined as C(V) = dQ/dV. You need to define the charge Q by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ C_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear capacitor, where Q = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, C = C(V) = dQ/dV = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Conductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK88.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear conductor model allows the conductor to be described by an arbitrary relationship between the conductor's current I and the voltage V across the conductor. In other words, I = f(V). The nonlinear conductance is then defined as G(V) = dI/dV. You need to define the current I by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ G_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear conductor, where I = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, G = G(V) = dI/dV = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Dependent Sources==&lt;br /&gt;
&lt;br /&gt;
[[File:G18.png]]&lt;br /&gt;
&lt;br /&gt;
Nonlinear dependent (arbitrary) sources use an equation or mathematical expression to describe their behavior. One and only one of the two forms: V=&amp;amp;lt;expr&amp;amp;gt; or  I=&amp;amp;lt;expr&amp;amp;gt; must be given.&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; v = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; i = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Examples: &lt;br /&gt;
&lt;br /&gt;
v = I(v1) + 3* I(v2)&lt;br /&gt;
&lt;br /&gt;
I = v(i1) + 3* v(2) + 5 * v(3) ^2&lt;br /&gt;
&lt;br /&gt;
The first example is a current-controlled voltage source.  The v on the left side of the equation&lt;br /&gt;
indicates that it is a voltage source.  I(v1) and I(v2) are the currents through voltage sources named v1 and v2, respectively.&lt;br /&gt;
&lt;br /&gt;
The second example is a voltage-controlled current source.  v(2) and v(3) represents the voltages at nodes 2 and 3, respectively, and v(i1) represents the voltage across a current source named i1.&lt;br /&gt;
&lt;br /&gt;
The following mathematical functions defined for real variables can be used in the expressions:&lt;br /&gt;
&lt;br /&gt;
abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), atanh(x), cos(x), cosh(x), exp(x), ln(x), log(x), max(x,y), min(x,y), pwr(x,y), pwrs(x,y), sgn(x), sin(x), sinh(x), sqrt(x), tan(x), tanh(x), u(x), uramp(x).&lt;br /&gt;
&lt;br /&gt;
The function &amp;amp;quot;sgn&amp;amp;quot; is the signum function and its value is 1 if the argument is positive or zero and -1 if the argument is negative. &lt;br /&gt;
The function &amp;amp;quot;u(x)&amp;amp;quot; is the unit step and &amp;amp;quot;uramp(x)&amp;amp;quot; is the integral of the unit step.  The&lt;br /&gt;
unit step is one if its argument is greater than zero and zero if its argument is less than zero.  The&lt;br /&gt;
ramp function (uramp) is 0 for argument values less than zero and equal to the argument for argument values&lt;br /&gt;
greater than zero.&lt;br /&gt;
&lt;br /&gt;
The following operators are permissible:  +, -, *, /, and ^.&lt;br /&gt;
&lt;br /&gt;
The power functions have equivalent expressions: pwr(x,y) = x^y and pwrs(x,y) = sgn(x)*abs(x)^y.&lt;br /&gt;
&lt;br /&gt;
Two constants can also be used in expressions: pi = 3.1415926 and e = 2.7182818.&lt;br /&gt;
&lt;br /&gt;
There is a conditional function with the syntax IF(Condition, Expression1, Expression2). If &amp;quot;Condition&amp;quot; is met, then the return value of the function is Expression1; otherwise, it is Expression2. An example of this type of function is IF(v(1)&amp;gt;=0,1,-1), which is equivalent to sgn(v(1)). &lt;br /&gt;
&lt;br /&gt;
To get time into an expression, integrate the current from a constant current source with a capacitor&lt;br /&gt;
and use the voltage across the capacitor.&lt;br /&gt;
&lt;br /&gt;
Note: All the functions and expressions are case-insensitive.&lt;br /&gt;
&lt;br /&gt;
==Nonlinear Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK90.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear inductor model allows the inductor to be described by an arbitrary relationship between the inductor's magnetic flux &amp;amp;Phi; and the current I flowing through the inductor . In other words, &amp;amp;Phi;  = f(I). The nonlinear inductance is then defined as L(I) = d&amp;amp;Phi;/dI. You need to define the flux &amp;amp;Phi; by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ L_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear inductor, where &amp;amp;Phi; = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, L = L(I) = d&amp;amp;Phi;/dI = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.  &lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(i(vx))^2.&lt;br /&gt;

==Nonlinear Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK87.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear resistor model allows the resistor to be described by an arbitrary relationship between the voltage V across the resistor and its current I. In other words, V = f(I). The nonlinear resistance is then defined as R(I) = dV/dI. You need to define the voltage V by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ R_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear resistor, where V = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, R = R(I) = dV/dI = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;

This three-pin device models a parameterized operational amplifier with a very high voltage gain, a very high input impedance and a very low output impedance. The behavioral model of the parameterized Op-Amp device is based on the algorithm found in the book &amp;lt;B&amp;gt;Macromodeling with Spice&amp;lt;/B&amp;gt;,&lt;br /&gt;
authored by Connelly &amp;amp;amp; Choi, published by Prentice Hall. The default parameters are those of the 741 Op-Amp. This device doesn't require external DC bias voltage sources. Its positive and negative DC bias voltages are specified as its parameters. Sometimes the simulation doesn't converge if there is no DC path from the output of the Op-Amp to the ground.&lt;br /&gt;

This is a five-pin parameterized optocoupler device. Its model consists of an ideal diode device in series with an Ohmic resistance connected between the Anode (A) and Cathode (K) pins together with a bipolar junction transistor device with three accessible pins, Collector (C), Base (B) and Emitter (E). A current-controlled current source is connected between base and collector of the BJT, whose current is controlled by the current passing through the diode. The proportionality constant is twice the specified value of the current transfer ratio (ctr) parameter. &lt;br /&gt;
&lt;br /&gt;
You can change or enhance the models of the diode and BJT by adding more parameters. To do so, you have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

[[File:GK113.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 4-pin parameterized photodiode device. A pair of pins, Anode (A) and Cathode (K), represent the physical terminals of the photodiode. The photodiode model connected between the anode and cathode pins consists of the parallel connection of an ideal diode, a dark current source, a noise current source, a current-controlled current source, a diode capacitance, a shunt resistance altogether with a series resistance.  &lt;br /&gt;
&lt;br /&gt;
Another pair of pins IS+ and IS- act as an ammeter that must be inserted in a control circuit. The current passing through this ammeter controls the current of the photodiode. The default proportionality constant is unity. The controlling current is typically a function of light intensity incident on the surface of the photodiode.    &lt;br /&gt;

==Piecewise Linear (PWL) Controlled Source==&lt;br /&gt;
&lt;br /&gt;
[[File:GL49.png]]&lt;br /&gt;
&lt;br /&gt;
The Piecewise Linear (PWL) Controlled Source is a single-input and single-output function generator whose output is not necessarily&lt;br /&gt;
linear for all input values. Instead, it follows an I/O relationship that is specified by the x_array and y_array coordinates. The x_array and y_array values represent vectors of coordinate points on the x and y axes, respectively. The x_array values are progressively increasing input coordinate points, and the associated y_array values represent the outputs at those points.  There may be as few as two pairs specified, or as many as memory and simulation speed allow.&lt;br /&gt;
&lt;br /&gt;
In order to fully specify outputs for values of Vin outside of the bounds of the PWL function, the PWL&lt;br /&gt;
controlled source model extends the slope found between the lowest two coordinate pairs and the highest&lt;br /&gt;
two coordinate pairs.  This has the effect of making the transfer function completely linear for Vin&lt;br /&gt;
less than x_array[0] and Vin greater than x_array[n]. It also has the potentially subtle effect of unrealistically&lt;br /&gt;
causing an output to reach a very large or small value for large inputs. You should thus keep in mind&lt;br /&gt;
that the PWL Source does not inherently provide a limiting capability.&lt;br /&gt;
&lt;br /&gt;
In order to diminish the potential for divergence of simulations when using the PWL block, a form&lt;br /&gt;
of smoothing around the x_array and y_array coordinate points is necessary.  This is due to the iterative&lt;br /&gt;
nature of the simulator and its reliance on smooth first derivatives of  transfer functions in order to&lt;br /&gt;
arrive at a matrix solution.  Consequently, the two parameters &amp;quot;input_domain&amp;quot; and &amp;quot;fraction&amp;quot; are included&lt;br /&gt;
to allow you some control over the amount and nature o the smoothing performed.&lt;br /&gt;
&lt;br /&gt;
Fraction is a switch that is either TRUE or FALSE.  When TRUE (the default setting), the simulator assumes&lt;br /&gt;
that the specified input_domain value is to be interpreted as a fractional figure.  Otherwise, it is interpreted&lt;br /&gt;
as an absolute value.  Thus, if fraction = TRUE and input_domain = 0.10, the simulator assumes that the smoothing&lt;br /&gt;
radius about each coordinate point is to be set equal to 10% of the length of either the x_array segment&lt;br /&gt;
above each coordinate point, or the x_array segment below each coordinate point. The specific segment&lt;br /&gt;
length chosen will be the smallest of these two for each coordinate point.&lt;br /&gt;
&lt;br /&gt;
If fraction = FALSE and input_domain = 0.10, then the simulator will begin smoothing the transfer function at 0.10&lt;br /&gt;
volts (or amperes) below each x_array coordinate and will continue the smoothing process for another 0.10&lt;br /&gt;
volts (or amperes) above each x_array coordinate point.&lt;br /&gt;

== Programmable Unijunction Transistor (PUT)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK112.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Programmable Unijunction Transistor (PUT) device with three pins: Base 1 (B1), Base 2 (B2) and Emitter (E). It is biased with a positive voltage between the two bases. This device has a unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. It exhibits a negative resistance characteristic and so it can be employed as an oscillator. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively. To change these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.    &lt;br /&gt;

==Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK119.png]]&lt;br /&gt;
&lt;br /&gt;
Resistors are passive devices that dissipate power. Their resistance value varies depending on how much power they can dissipate and is measured&lt;br /&gt;
in Ohms.  The transient, DC and AC behaviors of a resistor are all described by the same equation:&lt;br /&gt;
&lt;br /&gt;
v = R * i&lt;br /&gt;
&lt;br /&gt;
where v is the voltage across the resistor, i is the current passing through the resistor, and R is the resistance. The value of R must be nonzero. &lt;br /&gt;
&lt;br /&gt;
All resistor names must begin with R.&lt;br /&gt;

Example: &lt;br /&gt;
&lt;br /&gt;
R1 1 2 1k&lt;br /&gt;
&lt;br /&gt;
[[RF.Spice A/D]] provides three types of resistor: Simple, User-Defined (Real Resistor) and Semiconductor. The resistance of the simple resistor is a single value expressed in Ohms. You can also set the Monte Carlo tolerance for this resistor.&lt;br /&gt;
&lt;br /&gt;
==Schottky Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK80.png]]&lt;br /&gt;
&lt;br /&gt;
The Schottky diode has the same model as the generic diode with a nonzero transit time (tt), a nonzero junction capacitance (cjo) and a typically larger saturation current (is), a lower junction potential (vj) and a smaller grading coefficient (m).   &lt;br /&gt;
&lt;br /&gt;
==Semiconducting Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK83.png]]&lt;br /&gt;
&lt;br /&gt;
This is the more general form of the Capacitor model and allows for the calculation of the actual capacitance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
CXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;IC=VAL&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it defines the capacitance. If MNAME is specified, then the capacitance is calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. Either VALUE or MNAME, LENGTH, and WIDTH may be specified, but not both sets. The optional initial condition &amp;quot;IC&amp;quot; is the initial voltage across the capacitor for transient simulations.&lt;br /&gt;
&lt;br /&gt;
The capacitance is computed as:&lt;br /&gt;
&lt;br /&gt;
CAP = CJ * (LENGTH - NARROW) * (WIDTH - NARROW)+ 2 * CJSW * (LENGTH + WIDTH - 2NARROW) * CAP&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the capacitor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit CJ, CJSW, NARROW, DEFW, and CAP.&lt;br /&gt;

&lt;br /&gt;
If VALUE is specified, it overrides the geometric information and defines the resistance. If MNAME is specified, then the resistance may be calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. The (optional) TEMP value is the temperature at which this device is to operate, and overrides the temperature specification in the SPICE Options Dialog. &lt;br /&gt;
&lt;br /&gt;
The resistance is computed as:&lt;br /&gt;
&lt;br /&gt;
R(T0) = (RSH) * [(L - NARROW) / (W - NARROW)] * RES&lt;br /&gt;
&lt;br /&gt;
R(T) = R(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Silicon-Controlled Rectifier (SCR) device with three pins: Anode (A), Cathode (K) and Gate (G). It is a unidirectional device which can conduct current only in one direction. The SCR can be triggered only by a positive current going into its gate. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively.

== Triac Thyristor ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK110.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin bidirectional thyristor device that conducts current in either direction when triggered. A thyristor is analogous to a relay in that a small voltage and current can control a much larger voltage and current. The triac has two anode pins termed Main Terminal 1 (MT1) and Main Terminal 2 (MT2) and a Gate (G) pin. In order to create a triggering current for a triac, either a positive or negative voltage can be applied to the gate. Once triggered, the thyristor continues to conduct, even if the gate current ceases, until the main current drops below a certain level called the holding current. The device's model involves two NPN BJT transistors and two PNP BJT transistors. The forward beta parameters of the NPN and PNP transistors are set equal to 20 and 5, respectively. To changes these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.&lt;br /&gt;

==Uniform RC Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G23.png]]&lt;br /&gt;
&lt;br /&gt;
The standard parameters are L, and N.  They are described below:&lt;br /&gt;
&lt;br /&gt;
Two of the nodes are the element nodes connected by the RC line.  The third is the node to which the capacitances&lt;br /&gt;
are connected.  L is the length of the RC line in meters.  N is the number of lumped segments to use in&lt;br /&gt;
modeling the RC line.&lt;br /&gt;
&lt;br /&gt;
This device is derived from a model proposed by Gertzberrg.  It expands the URC line into a network of&lt;br /&gt;
lumped RC segments with internally generated nodes.  These segments increase toward the middle of the&lt;br /&gt;
URC line in a geometric progression with K as the proportionality constant.&lt;br /&gt;
&lt;br /&gt;
The URC line is made up entirely of resistor and capacitor segments, unless the ISPERL parameter has a&lt;br /&gt;
non-zero value.  In this case, capacitors are replaced by reverse biased diodes with an equivalent zero-bias&lt;br /&gt;
junction capacitance, a saturation current of ISPERL amps per meter of transmission line, and optional&lt;br /&gt;
series resistance of RSPERL ohms per meter. &lt;br /&gt;

==Voltage-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G19.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Voltage-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Voltmeter or controlling voltage nodes, as well as the turn-on and turn-off voltages in Volts and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the rest of [[parameters]]. When the voltage across the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the voltage across the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Voltage Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17A.png]]&lt;br /&gt;
&lt;br /&gt;
A voltage source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a voltage source is its initial transient value. For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset voltage. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;

&lt;br /&gt;
Note that XSpice devices must start with the &amp;amp;quot;A&amp;amp;quot; designation, much as a resistor starts with&lt;br /&gt;
an &amp;amp;quot;R&amp;amp;quot;.  Some devices will have grouped (or vector) pins and are designated by being placed&lt;br /&gt;
inside square brackets.  In the example shown below, the 1 and 2 pins are grouped.  Pin 3 is not.  &amp;lt;/P&amp;gt;&lt;br /&gt;

e.g., .model transfer_function s_xfer  in_offset = 0.0  gain = 1.0&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Model_name refers to the name given in the device line.  Model_identifier is an internal designation and&lt;br /&gt;
must be of an existing designation  Refer to each device's example for the correct designation. &lt;br /&gt;
&lt;br /&gt;

==Zener Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:G10.png]]&lt;br /&gt;
&lt;br /&gt;
The Zener Diode models the DC characteristics of most zeners. Since most data sheets for zener diodes do&lt;br /&gt;
not give detailed characteristics in the forward region, only a single point defines the forward characteristicThe&lt;br /&gt;
saturation current refers to the relatively constant reverse current that is produced when the voltage&lt;br /&gt;
across the zener is negative, but breakdown has not been reached.  The reverse leakage current determines&lt;br /&gt;
the slight increase in reverse current as the voltage across the zener becomes more negative.  It is modeled&lt;br /&gt;
as a resistance parallel to the zener with value v_breakdown / i_rev.&lt;br /&gt;
&lt;br /&gt;
Note that the limt_switch parameter engages an internal limiting function for the zener.  This can, in&lt;br /&gt;
some cases, prevent the simulator from converging to an unrealistic solution if the voltage across or&lt;br /&gt;
current into the device is excessive.  If use of this feature fails to yield acceptable results, the convlimit&lt;br /&gt;
option should be tried (add the following statement to the SPICE input deck:  .options convlimit)&lt;br /&gt;

==Analog-to-Digital Converter (ADC) Bridge==&lt;br /&gt;
[[File:GK42.png]]&lt;br /&gt;
&lt;br /&gt;
The ADC Bridge takes an analog value from an analog node and may be in the form of a voltage or current.&lt;br /&gt;
If the input is less than or equal to &amp;amp;quot;in_low&amp;amp;quot;, then a digital &amp;amp;quot;0&amp;amp;quot; is generated. If&lt;br /&gt;
the input is greater than or equal to &amp;amp;quot;in_high&amp;amp;quot;, a digital &amp;amp;quot;1&amp;amp;quot; is generated. Otherwise,&lt;br /&gt;
a digital &amp;amp;quot;UNKNOWN&amp;amp;quot; is the output value. Unlike the DAC Bridge, ramping or delay is not applicable.&lt;br /&gt;
Rather, the continuous ramping of the input provides for any associated delays in the digitized signal.&lt;br /&gt;
&lt;br /&gt;
This model also posts an input load value based on the parameter input_load.&lt;br /&gt;

==Bipolar Junction Transistor (BJT)==&lt;br /&gt;
[[File:G11.png]]&lt;br /&gt;
&lt;br /&gt;
The BJT is an active device which has up to 4 pins.  The three standard pins are base, emitter, and collector.  These are given in the default symbol.  The substrate, which is grounded by default, is the fourth pin.  To use the BJT with the substrate, create a new 4-pin BJT using the Device Editor and Symbol Editor.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|AREA||area factor (optional) (If not specified, the default value is 1.0.)&lt;br /&gt;
|-&lt;br /&gt;
|OFF||initial condition for the DC analysis (optional)&lt;br /&gt;
|-&lt;br /&gt;
|IC||initial condition (optional) (Used when a transient analysis is desired, which starts from other than the quiescent operating point.)&lt;br /&gt;
|-&lt;br /&gt;
|T||operating temperature of the device (optional)&lt;br /&gt;
|-&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Area factor scales the model parameters RE and RC.  IC VBE is the initial voltage from base emitter. IC VCE is the initial voltage from collector to emitter.  TEMP is the overriding temperature. These parameters are based on the Gummel and Poon integral-charge model.  If these parameters are not specified, then it will reduce to the simpler Ebers-Moll model. &lt;br /&gt;
&lt;br /&gt;
The process model is mandatory for the BJT.  Descriptions of the process model parameters are given in the following table:&lt;br /&gt;

==Capacitance Meter==&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Capacitance Meter measures the total capacitance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total capacitance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense a capacitance value and alter their behavior based upon it.&lt;br /&gt;

&lt;br /&gt;
==Capacitor==&lt;br /&gt;
[[File:GK120.png]]&lt;br /&gt;
&lt;br /&gt;
Capacitors are used to store electrical energy.  They can filter or remove AC signals or block DC current without disrupting AC signals. A capacitor's ability to store energy is termed capacitance and is measured in Farads, with values from pF to mF. The only time current flows through a capacitor is when the charge is collected on, or is removed from, its parallel plates. This means that the voltage across the capacitor is changing, which doesn't conform to DC analysis. In a physical circuit, there is a transition stage during which capacitors charge up to their final values. The result is the same as if these capacitors did not exist and the connections to them were left dangling. In other words, in a (steady-state) DC analysis, a capacitor behaves like an open circuit. Therefore, it is important that no section of the circuit is isolated from the capacitors. Every circuit node needs some path for DC current to the ground.&lt;br /&gt;
&lt;br /&gt;
A capacitor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
i(t) = C * (dv(t)/dt)&lt;br /&gt;
&lt;br /&gt;
Its initial voltage is only important when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked.&lt;br /&gt;
&lt;br /&gt;
An capacitor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
i = j ω * C * v &lt;br /&gt;
&lt;br /&gt;
All capacitor names must begin with C. &lt;br /&gt;

Example: &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
[[RF.Spice A/D]] provides three types of capacitors: simple, user-defined (or real) and semiconductor. The standard capacitor parameters are N+, N-, VALUE, and IC. In a simple capacitor, VALUE must&lt;br /&gt;
be specified for the capacitance in Farads. IC is the (optional) initial condition for the capacitor voltage.&lt;br /&gt;

This five-pin three-port device models a center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;
&lt;br /&gt;
To change the value of H/B arrays, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

==Controlled Sine Wave Oscillator==&lt;br /&gt;
&lt;br /&gt;
[[File:G24.png]]&lt;br /&gt;
&lt;br /&gt;
This is a four-terminal function generator with a sinusoidal wave output, whose frequency is controlled by an input voltage. The functional dependency of the output frequency on the input voltage is piecewise linear and is defined as a two-dimensional table similar to a piecewise linear (PWL) controlled source. In the &amp;quot;frequency vs. voltage&amp;quot; curve, the array &amp;quot;cntl_array&amp;quot; defines voltage values in Volts and the array &amp;quot;freq_array&amp;quot; defines the corresponding frequencies in Hz. &lt;br /&gt;
This function has parameterizable values of low and high peak output voltage.  &lt;br /&gt;

==Current Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17B.png]]&lt;br /&gt;
&lt;br /&gt;
Current source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a current source is its initial transient value.  For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset current. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==Current-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G20.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Current-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the turn-on and turn-off currents in Amperes and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the rest of [[parameters]]. When the current through the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the current through the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Darlington Pair==&lt;br /&gt;
&lt;br /&gt;
[[File:GK108.png]]&lt;br /&gt;
&lt;br /&gt;
A Darlington pair is a three-pin device that consists of two interconnected BJT transistors of the same type. The collectors of two transistors are connected together to provide the &amp;quot;Collector&amp;quot; pin of the pair. The base of the first BJT acts the &amp;quot;Base&amp;quot; pin of the pair. The emitter of the first BJT is internally connected to the base of the second BJT. The emitter of the second BJT acts as the &amp;quot;Emitter&amp;quot; pin of the pair. There are two types of Darlington pair: NPN and PNP. The parameterized generic Darlington pair also contains a diode connected between the collector and emitter pin as well as two base-emitter resistors, one across each BJT.     &lt;br /&gt;

==D Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G52.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type flip-flop is a one-bit, edge-triggered storage element which stores data whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). In addition, there are asynchronous set and reset signals, which are independent of the clock. When SET = RESET = 0, the data on the D line is transferred to the output Q on the rising edge of the clock. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

==D Latch==&lt;br /&gt;
&lt;br /&gt;
[[File:G54.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type latch is a one-bit, level-sensitive storage element which outputs the value on the data (D) line whenever the enable (EN) input line is 1 (high). The value on the data line is stored, i.e., held on the output (Q) line whenever the enable (EN) line is 0 (low). In addition, there are set and reset signals, which are independent of the enable line. When SET = RESET = 0, the data on the D line is transferred to the output Q whenever EN = 1. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

or &amp;amp;quot;U&amp;amp;quot;. It then outputs the value &amp;amp;quot;out_low&amp;amp;quot;, &amp;amp;quot;out_high&amp;amp;quot; or &amp;amp;quot;out_udndef&amp;amp;quot;,&lt;br /&gt;
or ramps linearly toward one of these &amp;amp;quot;final&amp;amp;quot; values from its curent analog output level. This&lt;br /&gt;
ramping speed depends on the values of &amp;amp;quot;t_rise&amp;amp;quot; and &amp;amp;quot;t_fall&amp;amp;quot;.&lt;br /&gt;

==Frequency Meter==&lt;br /&gt;
[[File:G114.png]]&lt;br /&gt;
&lt;br /&gt;
The Frequency Meter is a four-pin shunt device that is connected in parallel with an AC source just like a voltmeter and measures the operating frequency of the AC circuit. The input pins are connected across the AC source. The voltage across the output pins is equal to the frequency of the source in Hertz within a scale factor SF. Note that the Frequency Meter is designed to work with a single-tone AC source of unit amplitude. If the amplitude of the source is not one, multiply the SF parameter by the non-unit source amplitude value. The output voltage of the Frequency Meter can be used in conjunction with linear or nonlinear dependent sources to model frequency-dependent quantities.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Model Identifier: fmeter&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Parameters:&lt;br /&gt;
&lt;br /&gt;
The only parameter is the scale factor SF with a default value of 1.0. Set SF = 1e-6 to read out the frequency in MHz. Set SF = 1e-9 to read out the frequency in GHz. Set SF = 6.283185 (2*pi) to read out the angular frequency &amp;amp;omega; in radian/s.  &lt;br /&gt;
&lt;br /&gt;
== Fuse ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK76.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 2-pin interactive current-controlled switch. If the current passing through the fuse is less than a specified threshold current, the switch is closed. If the current exceeds the threshold level, the fuse breaks and remains open thereafter. The device's symbol changes to display its state.   &lt;br /&gt;

==Ground==&lt;br /&gt;
&lt;br /&gt;
[[File:G15.png]]&lt;br /&gt;
&lt;br /&gt;
Ground has a voltage of zero (0) and is used as a reference to compute electrical values in the circuit. &lt;br /&gt;
All circuits &amp;lt;B&amp;gt;must&amp;lt;/B&amp;gt; be grounded to be properly simulated.  There is no limit on the number of grounds&lt;br /&gt;
you may use in a circuit.  All components connected to ground are referenced to a common point and treated&lt;br /&gt;
as linked through ground.&lt;br /&gt;
&lt;br /&gt;
==Hysteresis Block (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Hysteresis block is a simple buffer stage that provides hysteresis of the output with respect to the&lt;br /&gt;
input.  The in_low and in_high parameter values.  The output values are limited to out_lower_limit and&lt;br /&gt;
out_upper_limit.  The value of \93hyst\94 is added to the in_low and in_high points in order to specify the&lt;br /&gt;
points at which the slope of the hysteresis function would normally change abruptly as the input transitions&lt;br /&gt;
from a low to a high value.  Likewise, the value of \93hyst\94 is subtracted from the in_high and in_low values&lt;br /&gt;
in order to specify the points at which the slope of the hysteresis function would normally change abruptly&lt;br /&gt;
as the input transitions from a high to a low value.  In fact, the slope of the hysteresis function is&lt;br /&gt;
never allowed to change abruptly but is smoothly varied whenever the input_dowmain smoothing parameter&lt;br /&gt;
is set greater than zero.&lt;br /&gt;

[[File:XFMR4.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal center-tapped transformer with push-pull input is a five-pin three-port device with two primary input ports and one secondary output port. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P1}{v_S} = \frac{v_P2}{v_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; is the secondary voltage, v&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt; is measured between the top primary pin P1 and the center tap pin, and v&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom primary pin P2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.        &lt;br /&gt;

==Ideal Center-Tapped Transformer with Push-Pull Output==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR3.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal center-tapped transformer with push-pull output is a five-pin three-port device with one primary input port and two secondary output ports. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_{S1}} = \frac{v_P}{v_{S2}} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; is the primary voltage, v&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; is measured between the top secondary pin S1 and the center tap pin, and v&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom secondary pin S2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.&lt;br /&gt;
&lt;br /&gt;
==Ideal Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK106.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device is a very basic and primitive model of a diode as a rectifier or switch. When the voltage across the device's terminals is positive, it acts as a short circuit. When the voltage across the device's terminals is negative, it acts as an open circuit.   &lt;br /&gt;

==Ideal Operational Amplifier (Op-Amp)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK105.png]]&lt;br /&gt;
&lt;br /&gt;
This is a very basic and primitive model of an operational amplifier. It has only one parameter, open loop gain with a default value of 50,000, which is adequate for most cases. The ideal Op-Amp device doesn't require any DC bias voltages. &lt;br /&gt;

==Ideal Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR1.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal transformer is a four-pin two-port device with the following relationship between the voltages and currents at its primary and secondary ports:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_S} = - \frac{i_S}{i_P} = \frac{N_P}{N_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; are the primary voltage, current and number of turns, respectively, and v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; are the secondary voltage, current and number of turns, respectively. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary turns ratio. Note that the ideal transformer model is defined based on controlled sources and does not involve any magnetic physical parameters as opposed to mutual inductors or ferrite core transformer.&lt;br /&gt;
&lt;br /&gt;
==Inductance Meter==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductance Meter measures the total inductance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total inductance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense an inductance value and alter their behavior based upon it. Care must be exercised when connecting an Inductance Meter to the inductors of a circuit. This is due to the fact that inductors are treated by SPICE as current sources. This can cause a problem when an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. &lt;br /&gt;

==Inductive Coupler Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GK99.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductive Coupler Block couples any two existing inductors. This block doesn't have any pins because it doesn't actually represent inductors, only the coupling between them. This is useful if you want to&lt;br /&gt;
couple two inductors that are in different parts of the circuit, or if you want to couple more than two inductors together. In the latter case, use more than one of these, with each one coupling a pair of inductors.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are Inductor1, Inductor2, and k. Inductor1 is the name of first inductor, Inductor2 is the name of the second inductor, and k is the coefficient of coupling, 0 &amp;amp;lt; k &amp;amp;le; 1.&lt;br /&gt;
&lt;br /&gt;
==Inductive Coupling (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G41.png]]&lt;br /&gt;
&lt;br /&gt;
This function is a conceptual model which is used as a building block to create a wide variety of inductive and magnetic circuit models. This function is normally used in&lt;br /&gt;
conjunction with the “core” model, but it can also be used with resistors, hysteresis blocks, etc. to build up systems which mock the behavior of linear and nonlinear components.&lt;br /&gt;
The lcouple takes as an input (on the “l” port) a current. This current value is multiplied by the num_turns value, N, to produce an output value (a voltage value which appears on the&lt;br /&gt;
mmf_out port). The mmf_out acts similar to a magnetomotive force in a magnetic circuit;&lt;br /&gt;
when the lcouple is connected to the “core” model, or to some other resistive device, a current will flow. This current value (which is modulated by whatever the lcouple is&lt;br /&gt;
connected to) is then used by the lcouple to calculate a voltage “seen” at the “l” port. The voltage is a function of the derivative with respect to time of the current value seen at mmf_out.&lt;br /&gt;
&lt;br /&gt;
The most common use for lcouple will be as a building block in the construction of transformer models. To create a transformer with a single input and a single output, you&lt;br /&gt;
would require two lcouple models plus one “core” model. &lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
A1 (1 0) (2 3) lcouple1&lt;br /&gt;
&lt;br /&gt;
.model lcouple1 lcouple ( num_turns = 10 )&lt;br /&gt;

==Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK121.png]]&lt;br /&gt;
&lt;br /&gt;
Inductors are used to store magnetic energy. An inductor's ability to counteract current changes passing through it is called its inductance (L), which is&lt;br /&gt;
measured in Henrys. In a (steady-state) DC analysis, the inductor acts like a short circuit. It is indeed treated as a current source, which can be problematic if an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. The resistor may be of negligible value or one that accounts for the coil resistance of the inductor. In AC and transient analyses, the inductor develops a voltage across it in response to the changing magnetic&lt;br /&gt;
flux within its coil. &lt;br /&gt;
&lt;br /&gt;
An inductor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
v(t) = L*(di(t)/dt) &lt;br /&gt;
&lt;br /&gt;
The inductor's initial condition is optional. It is the initial value of the inductor current in Amperes that flows from node N+ through the inductor to node N-. The only time that the initial current matters is when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked. &lt;br /&gt;
&lt;br /&gt;
An inductor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
v = j &amp;amp;omega; * L * i&lt;br /&gt;
&lt;br /&gt;
All inductor names must begin with L.&lt;br /&gt;

==Inductor with Ferrite Core==&lt;br /&gt;
&lt;br /&gt;
[[File:GK94.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device models a physical inductor with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. Unlike the standard inductor device, you do not specify an inductance value for the inductor with ferrite core. Rather, you specify physical parameters like cross sectional area, core length and number of turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;

== Insulated Gate Bipolar Transistor (IGBT)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK111.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Insulated Gate Bipolar Transistor (IGBT) device with three pins: Collector(C), Gate (G), and Emitter (E). It is primarily used as a fast electronic switch. The IGBT combines the simple gate-drive characteristics of MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors. The device's model consists of an isolated gate FET for the control input, and a PNP bipolar power transistor as a switch.

==JK Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G53.png]]&lt;br /&gt;
&lt;br /&gt;
The digital JK-type flip-flop is a one-bit, edge-triggered storage element which stores data whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). If J = 1 and K = 0, then the output is set (i.e. Q = 1) on the rising edge of the clock. If J = 0 and K = 1, then the output is reset (i.e. Q = 0). If J = K = 0, then the outputs do not change. If J = K = 1, then the outputs toggle on the positive edge of the clock signal. In addition, there are asynchronous set and reset signals, which are independent of the clock. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. &lt;br /&gt;

==Junction Field Effect Transistor (JFET)==&lt;br /&gt;
&lt;br /&gt;
[[File:G12.png]]&lt;br /&gt;
&lt;br /&gt;
The JFET is the simplest transistor device and has three pins: gate, drain and source. The JFET defaults are based on the Shichman and Hodges FET model. This is a square-law device because of the expression relating the drain current to the gate-to-source voltage: &lt;br /&gt;
Idrain=*(VGS-Vthreshold)2.  In real JFETs, near the saturation point, the drain currents vary with the drain voltages. This can be modeled by the following formula:  Idrain=*(VGS-VTO)2*(1+*VDS), which yields an increasing&lt;br /&gt;
drain current for increasing values of VDS.&lt;br /&gt;
&lt;br /&gt;
The gate-to-source and gate-to-drain junctions each have a nonlinear capacitor.  The zero-bias capacitance value is selected for each junction.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

&lt;br /&gt;
The CCCS is a current source whose current is directly proportional to the current across a controlling Ammeter or a voltage source. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the current gain, which has a default value of one. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the current gain.   &lt;br /&gt;

==Linear Voltage-Controlled Current Source (VCCS)==&lt;br /&gt;
&lt;br /&gt;
[[File:G3.png]]&lt;br /&gt;
&lt;br /&gt;
The VCCS is a current source whose current is directly proportional to the voltage across a controlling voltmeter or the voltage between two circuit nodes. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling voltmeter or the two controlling nodes, as well as the trans-conductance gain, which has a default value of one. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the trans-conductance gain.  &lt;br /&gt;

==Lossless Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G21.png]]&lt;br /&gt;
&lt;br /&gt;
The lossless transmission line is a four-pin two-port device that models only one propagating mode of an ideal transmission line.  When using this SPICE model, should all four nodes of the actual circuit be distinct, two modes may be activated, and this device would be insufficient for that purpose. To circumvent this potential problem, two transmission line devices would be required. Due to the implementation details, you may produce more accurate simulation results with a lossy transmission line device with zero loss.&lt;br /&gt;
&lt;br /&gt;
Optional initial condition parameters are the voltage and current at each of the transmission line ports.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are Z0, TD, F, NL, IC, described below:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|Z0||characteristic impedance&lt;br /&gt;
|-&lt;br /&gt;
|TD||transmission delay&lt;br /&gt;
|-&lt;br /&gt;
|F||frequency&lt;br /&gt;
|-&lt;br /&gt;
|NL||normalized electrical length of the transmission line with respect to the wavelength in the line at frequency F. (If F is specified, but NL is not, the default is 0.25.)&lt;br /&gt;
|-&lt;br /&gt;
|IC||initial condition (Specifies the voltage and current at each of the transmission line ports.)&lt;br /&gt;
|-&lt;br /&gt;

&lt;br /&gt;
==Lossy Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G22.png]]&lt;br /&gt;
&lt;br /&gt;
The lossy transmission line is a four-pin two-port convolution model for uniform constant-parameter distributed lines. MNAME is the process model name, which&lt;br /&gt;
includes a set of pre-specified options as described below.&lt;br /&gt;
&lt;br /&gt;
The device model [[parameters]] are listed in the following table:&lt;br /&gt;

The RLC (uniform transmission line with series loss only), RC (uniform RC line), LC (lossless transmission&lt;br /&gt;
line), and RG (distributed series resistance and parallel conductance only) lines have been implemented. &lt;br /&gt;
The length (LEN) must be given.  COMPACTREL and COMPACTABS control the compaction of past history values&lt;br /&gt;
used in convolution.  Larger values for these lower accuracy but improve speed.  These are used with the&lt;br /&gt;
TRYTOCOMPACT option. &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Magnetic Core (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G42.png]]&lt;br /&gt;
&lt;br /&gt;
This device is used as a building block to create a wide variety of inductive and magnetic circuit models. It is almost always to be used in conjunction with the &amp;quot;lcouple&amp;quot; model to build up systems which simulate the behavior of linear and nonlinear magnetic components. There are two fundamental modes of operation for the core model. These are the &amp;quot;PWL&amp;quot; mode (which is the default and most&lt;br /&gt;
likely to be of use to you) and the &amp;quot;Hysteresis&amp;quot; mode.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;PWL Mode (mode = 1)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the PWL mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf) value. This value is divided by the total effective length of the core to produce a value for the Magnetic Field Intensity, H, which is then used to find the corresponding Flux Density, B, using the piecewise linear relationship described by you in the H_array / B_array coordinate pairs. B is then multiplied by the cross-sectional area of the core to find the Flux value, which is output as a current. The pertinent mathematical equations are:&lt;br /&gt;
&lt;br /&gt;
H = mmf / L, where L = Length (in apmere-turns/meter)&lt;br /&gt;
&lt;br /&gt;
B = f(H)&lt;br /&gt;
&lt;br /&gt;
&amp;amp;Phi; = B * A, where A = Area&lt;br /&gt;
&lt;br /&gt;
The B value is derived from a piecewise linear transfer function described to the model by the H_array and B_array coordinate pairs.  This transfer function does not include hysteretic effects; for that, you would need to substitute a HYST model for the core. The magnetic flux value &amp;amp;Phi; in turn is used by the &amp;quot;lcouple&amp;quot;&lt;br /&gt;
code model to obtain a value for the voltage reflected back across its terminals to the driving electrical circuit.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Hysteresis Mode (mode = 2)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the Hysteresis mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf)&lt;br /&gt;
value.  This value is used as input to the equivalent of a hysteresis code model block.  The parameters&lt;br /&gt;
defining the input low and high values, the output low and high values, and the amount of hysteresis are&lt;br /&gt;
as in that model. The output from this mode, as in PWL mode, is a current value which is seen across the magnetic core port.&lt;br /&gt;
&lt;br /&gt;
One final note to be made about the two core models is that certain parameters are specific to one or the other.  In particular, the in_low, in_high, out_lower_limit, out_upper_limit, and hysteresis parameters are not available in PWL mode. Likewise, the H_array, B_array, area, ad length values are unavailable&lt;br /&gt;
in Hysteresis mode.  The input_domain and fraction parameters are common to both modes (though their behavior is somewhat different; for explanation of the input_domain and fraction values for the Hysteresis mode, please refer to the Hysteresis Block discussion.&lt;br /&gt;

==Marker==&lt;br /&gt;
&lt;br /&gt;
[[File:G16.png]]&lt;br /&gt;
&lt;br /&gt;
The marker serves several purposes:&lt;br /&gt;
&lt;br /&gt;
* It can appear as a default plot in simulations if the &amp;amp;quot;Voltage Probe&amp;amp;quot; box is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to set the initial voltage or voltage guess at the node it is connected to.&lt;br /&gt;
&lt;br /&gt;
* It can be used as a port for a subcircuit when you choose the checkbox labeled &amp;quot;Use as Subcircuit Port&amp;quot; is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to explicitly set a node number in place of the arbitrarily assigned node number by the program. In this case, make sure the &amp;amp;quot;Set Node Index&amp;amp;quot; box is checked.  Otherwise, it will act as just a voltage probe.&lt;br /&gt;
&lt;br /&gt;
* It can be used to connect different parts of a circuit in place of wires. To use markers as virtual connectors, place them at points where wires would otherwise connect. Then set the Part Title of the two (or more) markers to the same name, and they will act as a single circuit node.&lt;br /&gt;
&lt;br /&gt;
==MESFET==&lt;br /&gt;
&lt;br /&gt;
[[File:G14.png]]&lt;br /&gt;
&lt;br /&gt;
The MESFET is a Schottky-barrier gate FET with six times greater electron mobility than silicon.  MESFETs are important devices for creating high frequency circuits. They function by creating a potential barrier between the gate and the channel when the metal gate&lt;br /&gt;
contacts the gallium-arsenide substrate. Electron velocity saturates for fields approximately ten times lower than with silicon.  The Curtice model includes linear and saturated operation.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|AREA||area factor (optional) (If not specified, the default value is 1.0.)&lt;br /&gt;
|-&lt;br /&gt;
|OFF||initial condition for the DC analysis (optional)&lt;br /&gt;
|-&lt;br /&gt;

&lt;br /&gt;
The MOSFET is an active device that has up to 4 pins.  The three standard pins are gate, drain, and source.  These are given in the default symbol.  The bulk node, which is grounded by default, is the fourth pin.  The MOSFET with the bulk is named mos_n_lvl1_4 (the lvl1 is for level 1, the n for nmos, and the 4 for 4 pins.)&lt;br /&gt;
&lt;br /&gt;
The standard [[parameters]] are L, W, AD, AS, PD, PS, NRD, NRS, OFF, IC, and T.  They are described below:&lt;br /&gt;

There are five different default models: square-law I-V characteristic, analytical, semi-empirical, and BSIM and BSIM2 (Berkeley Short-channel IGFET Model), which include second-order effects such as channel-length&lt;br /&gt;
modulation, subthreshold conduction, scattering-limited velocity saturation, small-size effects, and charge-controlled capacitance.  The process parameter LEVEL specifies which of the models is chosen as indicated below:&lt;br /&gt;

You have to specify the inductance of inductor L1, the inductance of inductor L2, the initial current through each, and the coupling coefficient k, 0 &amp;amp;le; k &amp;amp;le; 1. The mutual inductance M expressed in units of H can be calculated using the following definition:&lt;br /&gt;

&lt;br /&gt;
This 8-pin device models a non-ideal lossy current transformer. Its model consists of an ideal transformer with more secondary turns than primary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. on each side of the internal ideal transformer, there is a series leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, followed by a shunt winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a series winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, which connects to the exterior positive pin on that side. The inter-winding resistance R&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the negative pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance. &lt;br /&gt;

This 2-pin device is a basic simplified model of a diode as a rectifier or switch. When forward-biased, it acts as a low-valued voltage source. When reverse-biased, it acts as an open circuit until the reverse voltage exceeds the specified breakdown voltage. Then it acts as a high-valued voltage source of the reverse polarity. &lt;br /&gt;

The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer.

These are connected between the positive interior and exterior pins on each side. There are also two shunt branches at the inputs of the primary and secondary sides (connected between the positive and negative exterior pins), each consisting of a distributed turn-to-turn winding resistance RDC&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; in series with a distributed turn-to-turn winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;. The inter-winding capacitance CWW&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the positive pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance.  &lt;br /&gt;

==Nonlinear Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK89.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear capacitor model allows the capacitor to be described by an arbitrary relationship between the capacitor's charge Q and the voltage V across the capacitor. In other words, Q = f(V). The nonlinear capacitance is then defined as C(V) = dQ/dV. You need to define the charge Q by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ C_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear capacitor, where Q = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, C = C(V) = dQ/dV = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Conductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK88.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear conductor model allows the conductor to be described by an arbitrary relationship between the conductor's current I and the voltage V across the conductor. In other words, I = f(V). The nonlinear conductance is then defined as G(V) = dI/dV. You need to define the current I by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ G_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear conductor, where I = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, G = G(V) = dI/dV = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Dependent Sources==&lt;br /&gt;
&lt;br /&gt;
[[File:G18.png]]&lt;br /&gt;
&lt;br /&gt;
Nonlinear dependent (arbitrary) sources use an equation or mathematical expression to describe their behavior. One and only one of the two forms: V=&amp;amp;lt;expr&amp;amp;gt; or  I=&amp;amp;lt;expr&amp;amp;gt; must be given.&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; v = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; i = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Examples: &lt;br /&gt;
&lt;br /&gt;
v = I(v1) + 3* I(v2)&lt;br /&gt;
&lt;br /&gt;
I = v(i1) + 3* v(2) + 5 * v(3) ^2&lt;br /&gt;
&lt;br /&gt;
The first example is a current-controlled voltage source.  The v on the left side of the equation&lt;br /&gt;
indicates that it is a voltage source.  I(v1) and I(v2) are the currents through voltage sources named v1 and v2, respectively.&lt;br /&gt;
&lt;br /&gt;
The second example is a voltage-controlled current source.  v(2) and v(3) represents the voltages at nodes 2 and 3, respectively, and v(i1) represents the voltage across a current source named i1.&lt;br /&gt;
&lt;br /&gt;
The following mathematical functions defined for real variables can be used in the expressions:&lt;br /&gt;
&lt;br /&gt;
abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), atanh(x), cos(x), cosh(x), exp(x), ln(x), log(x), max(x,y), min(x,y), pwr(x,y), pwrs(x,y), sgn(x), sin(x), sinh(x), sqrt(x), tan(x), tanh(x), u(x), uramp(x).&lt;br /&gt;
&lt;br /&gt;
The function &amp;amp;quot;sgn&amp;amp;quot; is the signum function and its value is 1 if the argument is positive or zero and -1 if the argument is negative. &lt;br /&gt;
The function &amp;amp;quot;u(x)&amp;amp;quot; is the unit step and &amp;amp;quot;uramp(x)&amp;amp;quot; is the integral of the unit step.  The&lt;br /&gt;
unit step is one if its argument is greater than zero and zero if its argument is less than zero.  The&lt;br /&gt;
ramp function (uramp) is 0 for argument values less than zero and equal to the argument for argument values&lt;br /&gt;
greater than zero.&lt;br /&gt;
&lt;br /&gt;
The following operators are permissible:  +, -, *, /, and ^.&lt;br /&gt;
&lt;br /&gt;
The power functions have equivalent expressions: pwr(x,y) = x^y and pwrs(x,y) = sgn(x)*abs(x)^y.&lt;br /&gt;
&lt;br /&gt;
Two constants can also be used in expressions: pi = 3.1415926 and e = 2.7182818.&lt;br /&gt;
&lt;br /&gt;
There is a conditional function with the syntax IF(Condition, Expression1, Expression2). If &amp;quot;Condition&amp;quot; is met, then the return value of the function is Expression1; otherwise, it is Expression2. An example of this type of function is IF(v(1)&amp;gt;=0,1,-1), which is equivalent to sgn(v(1)). &lt;br /&gt;
&lt;br /&gt;
To get time into an expression, integrate the current from a constant current source with a capacitor&lt;br /&gt;
and use the voltage across the capacitor.&lt;br /&gt;
&lt;br /&gt;
Note: All the functions and expressions are case-insensitive.&lt;br /&gt;
&lt;br /&gt;
==Nonlinear Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK90.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear inductor model allows the inductor to be described by an arbitrary relationship between the inductor's magnetic flux &amp;amp;Phi; and the current I flowing through the inductor . In other words, &amp;amp;Phi;  = f(I). The nonlinear inductance is then defined as L(I) = d&amp;amp;Phi;/dI. You need to define the flux &amp;amp;Phi; by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ L_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear inductor, where &amp;amp;Phi; = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, L = L(I) = d&amp;amp;Phi;/dI = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.  &lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(i(vx))^2.&lt;br /&gt;

==Nonlinear Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK87.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear resistor model allows the resistor to be described by an arbitrary relationship between the voltage V across the resistor and its current I. In other words, V = f(I). The nonlinear resistance is then defined as R(I) = dV/dI. You need to define the voltage V by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ R_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear resistor, where V = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, R = R(I) = dV/dI = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 10*(i(vx))^2.&lt;br /&gt;

&lt;br /&gt;
This three-pin device models a parameterized operational amplifier with a very high voltage gain, a very high input impedance and a very low output impedance. The behavioral model of the parameterized Op-Amp device is based on the algorithm found in the book &amp;lt;B&amp;gt;Macromodeling with Spice&amp;lt;/B&amp;gt;,&lt;br /&gt;
authored by Connelly &amp;amp;amp; Choi, published by Prentice Hall. The default parameters are those of the 741 Op-Amp. This device doesn't require external DC bias voltage sources. Its positive and negative DC bias voltages are specified as its parameters. Sometimes the simulation doesn't converge if there is no DC path from the output of the Op-Amp to the ground.&lt;br /&gt;

== Optocoupler ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK115.png]]&lt;br /&gt;
&lt;br /&gt;
This is a five-pin parameterized optocoupler device. Its model consists of an ideal diode device in series with an Ohmic resistance connected between the Anode (A) and Cathode (K) pins together with a bipolar junction transistor device with three accessible pins, Collector (C), Base (B) and Emitter (E). A current-controlled current source is connected between base and collector of the BJT, whose current is controlled by the current passing through the diode. The proportionality constant is twice the specified value of the current transfer ratio (ctr) parameter. &lt;br /&gt;
&lt;br /&gt;
You can change or enhance the models of the diode and BJT by adding more parameters. To do so, you have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

&lt;br /&gt;
This is a 4-pin parameterized photodiode device. A pair of pins, Anode (A) and Cathode (K), represent the physical terminals of the photodiode. The photodiode model connected between the anode and cathode pins consists of the parallel connection of an ideal diode, a dark current source, a noise current source, a current-controlled current source, a diode capacitance, a shunt resistance altogether with a series resistance.  &lt;br /&gt;
&lt;br /&gt;
Another pair of pins IS+ and IS- act as an ammeter that must be inserted in a control circuit. The current passing through this ammeter controls the current of the photodiode. The default proportionality constant is unity. The controlling current is typically a function of light intensity incident on the surface of the photodiode.    &lt;br /&gt;

==Piecewise Linear (PWL) Controlled Source==&lt;br /&gt;
&lt;br /&gt;
[[File:GL49.png]]&lt;br /&gt;
&lt;br /&gt;
The Piecewise Linear (PWL) Controlled Source is a single-input and single-output function generator whose output is not necessarily&lt;br /&gt;
linear for all input values. Instead, it follows an I/O relationship that is specified by the x_array and y_array coordinates. The x_array and y_array values represent vectors of coordinate points on the x and y axes, respectively. The x_array values are progressively increasing input coordinate points, and the associated y_array values represent the outputs at those points.  There may be as few as two pairs specified, or as many as memory and simulation speed allow.&lt;br /&gt;
&lt;br /&gt;
In order to fully specify outputs for values of Vin outside of the bounds of the PWL function, the PWL&lt;br /&gt;
controlled source model extends the slope found between the lowest two coordinate pairs and the highest&lt;br /&gt;
two coordinate pairs.  This has the effect of making the transfer function completely linear for Vin&lt;br /&gt;
less than x_array[0] and Vin greater than x_array[n]. It also has the potentially subtle effect of unrealistically&lt;br /&gt;
causing an output to reach a very large or small value for large inputs. You should thus keep in mind&lt;br /&gt;
that the PWL Source does not inherently provide a limiting capability.&lt;br /&gt;
&lt;br /&gt;
In order to diminish the potential for divergence of simulations when using the PWL block, a form&lt;br /&gt;
of smoothing around the x_array and y_array coordinate points is necessary.  This is due to the iterative&lt;br /&gt;
nature of the simulator and its reliance on smooth first derivatives of  transfer functions in order to&lt;br /&gt;
arrive at a matrix solution.  Consequently, the two parameters &amp;quot;input_domain&amp;quot; and &amp;quot;fraction&amp;quot; are included&lt;br /&gt;
to allow you some control over the amount and nature o the smoothing performed.&lt;br /&gt;
&lt;br /&gt;
Fraction is a switch that is either TRUE or FALSE.  When TRUE (the default setting), the simulator assumes&lt;br /&gt;
that the specified input_domain value is to be interpreted as a fractional figure.  Otherwise, it is interpreted&lt;br /&gt;
as an absolute value.  Thus, if fraction = TRUE and input_domain = 0.10, the simulator assumes that the smoothing&lt;br /&gt;
radius about each coordinate point is to be set equal to 10% of the length of either the x_array segment&lt;br /&gt;
above each coordinate point, or the x_array segment below each coordinate point. The specific segment&lt;br /&gt;
length chosen will be the smallest of these two for each coordinate point.&lt;br /&gt;
&lt;br /&gt;
If fraction = FALSE and input_domain = 0.10, then the simulator will begin smoothing the transfer function at 0.10&lt;br /&gt;
volts (or amperes) below each x_array coordinate and will continue the smoothing process for another 0.10&lt;br /&gt;
volts (or amperes) above each x_array coordinate point.&lt;br /&gt;

[[File:GK112.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Programmable Unijunction Transistor (PUT) device with three pins: Base 1 (B1), Base 2 (B2) and Emitter (E). It is biased with a positive voltage between the two bases. This device has a unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. It exhibits a negative resistance characteristic and so it can be employed as an oscillator. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively. To change these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.    &lt;br /&gt;

==Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK119.png]]&lt;br /&gt;
&lt;br /&gt;
Resistors are passive devices that dissipate power. Their resistance value varies depending on how much power they can dissipate and is measured&lt;br /&gt;
in Ohms.  The transient, DC and AC behaviors of a resistor are all described by the same equation:&lt;br /&gt;
&lt;br /&gt;
v = R * i&lt;br /&gt;
&lt;br /&gt;
where v is the voltage across the resistor, i is the current passing through the resistor, and R is the resistance. The value of R must be nonzero. &lt;br /&gt;
&lt;br /&gt;
All resistor names must begin with R.&lt;br /&gt;
&lt;br /&gt;

R&amp;lt;device_name&amp;gt; &amp;lt;N+&amp;gt; &amp;lt;N-&amp;gt; &amp;lt;value&amp;gt; &lt;br /&gt;
&lt;br /&gt;
Example: &lt;br /&gt;
&lt;br /&gt;
R1 1 2 1k&lt;br /&gt;
&lt;br /&gt;
[[RF.Spice A/D]] provides three types of resistor: Simple, User-Defined (Real Resistor) and Semiconductor. The resistance of the simple resistor is a single value expressed in Ohms. You can also set the Monte Carlo tolerance for this resistor.&lt;br /&gt;
&lt;br /&gt;
==Schottky Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK80.png]]&lt;br /&gt;
&lt;br /&gt;
The Schottky diode has the same model as the generic diode with a nonzero transit time (tt), a nonzero junction capacitance (cjo) and a typically larger saturation current (is), a lower junction potential (vj) and a smaller grading coefficient (m).   &lt;br /&gt;
&lt;br /&gt;
==Semiconducting Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK83.png]]&lt;br /&gt;
&lt;br /&gt;
This is the more general form of the Capacitor model and allows for the calculation of the actual capacitance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
CXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;IC=VAL&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it defines the capacitance. If MNAME is specified, then the capacitance is calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. Either VALUE or MNAME, LENGTH, and WIDTH may be specified, but not both sets. The optional initial condition &amp;quot;IC&amp;quot; is the initial voltage across the capacitor for transient simulations.&lt;br /&gt;
&lt;br /&gt;
The capacitance is computed as:&lt;br /&gt;
&lt;br /&gt;
CAP = CJ * (LENGTH - NARROW) * (WIDTH - NARROW)+ 2 * CJSW * (LENGTH + WIDTH - 2NARROW) * CAP&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the capacitor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit CJ, CJSW, NARROW, DEFW, and CAP.&lt;br /&gt;

&lt;br /&gt;
This is the more general form of the resistor model and allows for the modeling of temperature effects and for the calculation of the actual resistance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
RXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;TEMP=T&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it overrides the geometric information and defines the resistance. If MNAME is specified, then the resistance may be calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. The (optional) TEMP value is the temperature at which this device is to operate, and overrides the temperature specification in the SPICE Options Dialog. &lt;br /&gt;
&lt;br /&gt;
The resistance is computed as:&lt;br /&gt;
&lt;br /&gt;
R(T0) = (RSH) * [(L - NARROW) / (W - NARROW)] * RES&lt;br /&gt;
&lt;br /&gt;
R(T) = R(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the resistor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit TC1, TC2, RSH, RES, etc.&lt;br /&gt;

== Silicon-Controlled Rectifier (SCR)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK109.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Silicon-Controlled Rectifier (SCR) device with three pins: Anode (A), Cathode (K) and Gate (G). It is a unidirectional device which can conduct current only in one direction. The SCR can be triggered only by a positive current going into its gate. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively. To changes these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.    &lt;br /&gt;

==SR Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G59.png]]&lt;br /&gt;
&lt;br /&gt;
The digital SR-type flip-flop is a one-bit, edge-triggered storage element which stores data whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). The value stored on the output Q line will depend on the S and R input line values. If S = 1 and R = 0, the output is set (i.e. Q = 1) on the rising edge of the clock. If S = 0 and R = 1, the output is reset (i.e. Q = 0) on the rising edge of the clock. If both inputs are S = R = 0, then the outputs do not change from the previous state. If both inputs are S = R = 1, then the result is unknown. In addition, there are asynchronous set and reset signals, which are independent of the clock input. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. &lt;br /&gt;

==SR Latch==&lt;br /&gt;
&lt;br /&gt;
[[File:G58.png]]&lt;br /&gt;
&lt;br /&gt;
The digital SR-type latch is a one-bit, level-sensitive storage element which outputs the value dictated by the state of the S and R input lines whenever the enable (EN) input line is 1 (high). This value is stored (i.e., held on the output line) whenever the enable (EN) line is 0 (low). If S = 1 and R = 0, the latch is set (i.e. Q = 1). If S = 0 and R = 1, the latch is reset (i.e. Q = 0). If both inputs are S = R = 0, then the outputs do not change from the previous state. If both inputs are S = R = 1, then the result is unknown. In addition, there are set and reset signals, which are independent of the enable line. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. &lt;br /&gt;

The tabulated conductor model allows the conductance to be described by a table relating the device's current i(t) to its terminal voltage v(t). In effect, the conductance is defined as G = di(t)/dv(t). The model provides two interpolation options: cubic spline and piecewise linear.

== Temperature-Dependent Current Source ==&lt;br /&gt;
&lt;br /&gt;
[[File:GL14.png]]&lt;br /&gt;
&lt;br /&gt;
This is a current source whose current is an arbitrary function of the circuit temperature. You have to open the subcircuit model dialog by clicking the {{key|Edit Model...}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(T)&amp;quot; standing for temperature. Note that the circuit temperature is set and controlled by the parameter &amp;quot;temp&amp;quot; in the Miscellaneous tab of the SPICE [[Simulation Options]] dialog.  &lt;br /&gt;
&lt;br /&gt;
Examples:&lt;br /&gt;
&lt;br /&gt;
* v(T) is equivalent to f(T) = T.&lt;br /&gt;
* 1 + 0.1*(v(t))^2 is equivalent to f(T) = 1 + 0.1T.&lt;br /&gt;

==Thermometer==&lt;br /&gt;
[[File:G115.png]]&lt;br /&gt;
&lt;br /&gt;
The Thermometer is a two-pin device that measures the operating temperature of a circuit. The voltage across the device pins is equal to SPICE's operating temperature in degrees centigrade. The output voltage of the Thermometer can be used in conjunction with linear or nonlinear dependent sources to model temperature-dependent quantities.&lt;br /&gt;

==Toggle Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G55.png]]&lt;br /&gt;
&lt;br /&gt;
The digital T-type flip-flop is a one-bit, edge-triggered storage element which toggles its current state whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). When the toggle (T) line is zero, the flip-flop is inactive. When T is high, the flip-flop's output toggles its value on the rising edge of the clock. In addition, there are asynchronous set and reset signals, which are independent of the clock input. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. &lt;br /&gt;

== Triac Thyristor ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK110.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin bidirectional thyristor device that conducts current in either direction when triggered. A thyristor is analogous to a relay in that a small voltage and current can control a much larger voltage and current. The triac has two anode pins termed Main Terminal 1 (MT1) and Main Terminal 2 (MT2) and a Gate (G) pin. In order to create a triggering current for a triac, either a positive or negative voltage can be applied to the gate. Once triggered, the thyristor continues to conduct, even if the gate current ceases, until the main current drops below a certain level called the holding current. The device's model involves two NPN BJT transistors and two PNP BJT transistors. The forward beta parameters of the NPN and PNP transistors are set equal to 20 and 5, respectively. To changes these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.&lt;br /&gt;

==Uniform RC Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G23.png]]&lt;br /&gt;
&lt;br /&gt;
The standard parameters are L, and N.  They are described below:&lt;br /&gt;
&lt;br /&gt;
Two of the nodes are the element nodes connected by the RC line.  The third is the node to which the capacitances&lt;br /&gt;
are connected.  L is the length of the RC line in meters.  N is the number of lumped segments to use in&lt;br /&gt;
modeling the RC line.&lt;br /&gt;
&lt;br /&gt;
This device is derived from a model proposed by Gertzberrg.  It expands the URC line into a network of&lt;br /&gt;
lumped RC segments with internally generated nodes.  These segments increase toward the middle of the&lt;br /&gt;
URC line in a geometric progression with K as the proportionality constant.&lt;br /&gt;
&lt;br /&gt;
The URC line is made up entirely of resistor and capacitor segments, unless the ISPERL parameter has a&lt;br /&gt;
non-zero value.  In this case, capacitors are replaced by reverse biased diodes with an equivalent zero-bias&lt;br /&gt;
junction capacitance, a saturation current of ISPERL amps per meter of transmission line, and optional&lt;br /&gt;
series resistance of RSPERL ohms per meter. &lt;br /&gt;

==Voltage-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G19.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Voltage-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Voltmeter or controlling voltage nodes, as well as the turn-on and turn-off voltages in Volts and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the rest of [[parameters]]. When the voltage across the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the voltage across the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Voltage Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17A.png]]&lt;br /&gt;
&lt;br /&gt;
A voltage source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a voltage source is its initial transient value. For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset voltage. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==XSpice Devices and their models==&lt;br /&gt;

e.g., A2 1  2  transfer_function&lt;br /&gt;
&lt;br /&gt;
Note that XSpice devices must start with the &amp;amp;quot;A&amp;amp;quot; designation, much as a resistor starts with&lt;br /&gt;
an &amp;amp;quot;R&amp;amp;quot;.  Some devices will have grouped (or vector) pins and are designated by being placed&lt;br /&gt;
inside square brackets.  In the example shown below, the 1 and 2 pins are grouped.  Pin 3 is not.  &amp;lt;/P&amp;gt;&lt;br /&gt;

Some models will have voltage differential pairs of pins and will be denoted by a %vd( ).  In the following&lt;br /&gt;
example pins 1 and 4 are differential pairs, as well as pins 2 and 3.  Differential pairs must go between&lt;br /&gt;
parentheses (). &lt;br /&gt;

e.g., .model transfer_function s_xfer  in_offset = 0.0  gain = 1.0&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Model_name refers to the name given in the device line.  Model_identifier is an internal designation and&lt;br /&gt;
must be of an existing designation  Refer to each device's example for the correct designation. &lt;br /&gt;
&lt;br /&gt;
Parameter values are optional.  If they aren't specified, then the default will be used.  Some devices&lt;br /&gt;
have parameters that require a value and must be specified.  Refer to individual devices for any required parameters.&lt;br /&gt;
&lt;br /&gt;
==Zener Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:G10.png]]&lt;br /&gt;
&lt;br /&gt;
The Zener Diode models the DC characteristics of most zeners. Since most data sheets for zener diodes do&lt;br /&gt;
not give detailed characteristics in the forward region, only a single point defines the forward characteristicThe&lt;br /&gt;
saturation current refers to the relatively constant reverse current that is produced when the voltage&lt;br /&gt;
across the zener is negative, but breakdown has not been reached.  The reverse leakage current determines&lt;br /&gt;
the slight increase in reverse current as the voltage across the zener becomes more negative.  It is modeled&lt;br /&gt;
as a resistance parallel to the zener with value v_breakdown / i_rev.&lt;br /&gt;
&lt;br /&gt;
Note that the limt_switch parameter engages an internal limiting function for the zener.  This can, in&lt;br /&gt;
some cases, prevent the simulator from converging to an unrealistic solution if the voltage across or&lt;br /&gt;
current into the device is excessive.  If use of this feature fails to yield acceptable results, the convlimit&lt;br /&gt;
option should be tried (add the following statement to the SPICE input deck:  .options convlimit)&lt;br /&gt;

==Analog-to-Digital Converter (ADC) Bridge==&lt;br /&gt;
[[File:GK42.png]]&lt;br /&gt;
&lt;br /&gt;
The ADC Bridge takes an analog value from an analog node and may be in the form of a voltage or current.&lt;br /&gt;
If the input is less than or equal to &amp;amp;quot;in_low&amp;amp;quot;, then a digital &amp;amp;quot;0&amp;amp;quot; is generated. If&lt;br /&gt;
the input is greater than or equal to &amp;amp;quot;in_high&amp;amp;quot;, a digital &amp;amp;quot;1&amp;amp;quot; is generated. Otherwise,&lt;br /&gt;
a digital &amp;amp;quot;UNKNOWN&amp;amp;quot; is the output value. Unlike the DAC Bridge, ramping or delay is not applicable.&lt;br /&gt;
Rather, the continuous ramping of the input provides for any associated delays in the digitized signal.&lt;br /&gt;
&lt;br /&gt;
This model also posts an input load value based on the parameter input_load.&lt;br /&gt;

==Bipolar Junction Transistor (BJT)==&lt;br /&gt;
[[File:G11.png]]&lt;br /&gt;
&lt;br /&gt;
The BJT is an active device which has up to 4 pins.  The three standard pins are base, emitter, and collector.  These are given in the default symbol.  The substrate, which is grounded by default, is the fourth pin.  To use the BJT with the substrate, create a new 4-pin BJT using the Device Editor and Symbol Editor.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|AREA||area factor (optional) (If not specified, the default value is 1.0.)&lt;br /&gt;
|-&lt;br /&gt;
|OFF||initial condition for the DC analysis (optional)&lt;br /&gt;
|-&lt;br /&gt;
|IC||initial condition (optional) (Used when a transient analysis is desired, which starts from other than the quiescent operating point.)&lt;br /&gt;
|-&lt;br /&gt;
|T||operating temperature of the device (optional)&lt;br /&gt;
|-&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Area factor scales the model parameters RE and RC.  IC VBE is the initial voltage from base emitter. IC VCE is the initial voltage from collector to emitter.  TEMP is the overriding temperature. These parameters are based on the Gummel and Poon integral-charge model.  If these parameters are not specified, then it will reduce to the simpler Ebers-Moll model. &lt;br /&gt;
&lt;br /&gt;
The process model is mandatory for the BJT.  Descriptions of the process model parameters are given in the following table:&lt;br /&gt;

==Capacitance Meter==&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Capacitance Meter measures the total capacitance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total capacitance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense a capacitance value and alter their behavior based upon it.&lt;br /&gt;

&lt;br /&gt;
==Capacitor==&lt;br /&gt;
[[File:GK120.png]]&lt;br /&gt;
&lt;br /&gt;
Capacitors are used to store electrical energy.  They can filter or remove AC signals or block DC current without disrupting AC signals. A capacitor's ability to store energy is termed capacitance and is measured in Farads, with values from pF to mF. The only time current flows through a capacitor is when the charge is collected on, or is removed from, its parallel plates. This means that the voltage across the capacitor is changing, which doesn't conform to DC analysis. In a physical circuit, there is a transition stage during which capacitors charge up to their final values. The result is the same as if these capacitors did not exist and the connections to them were left dangling. In other words, in a (steady-state) DC analysis, a capacitor behaves like an open circuit. Therefore, it is important that no section of the circuit is isolated from the capacitors. Every circuit node needs some path for DC current to the ground.&lt;br /&gt;
&lt;br /&gt;
A capacitor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
i(t) = C * (dv(t)/dt)&lt;br /&gt;
&lt;br /&gt;
Its initial voltage is only important when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked.&lt;br /&gt;
&lt;br /&gt;
An capacitor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
i = j ω * C * v &lt;br /&gt;
&lt;br /&gt;
All capacitor names must begin with C. &lt;br /&gt;

&lt;br /&gt;
[[RF.Spice A/D]] provides three types of capacitors: simple, user-defined (or real) and semiconductor. The standard capacitor parameters are N+, N-, VALUE, and IC. In a simple capacitor, VALUE must&lt;br /&gt;
be specified for the capacitance in Farads. IC is the (optional) initial condition for the capacitor voltage.&lt;br /&gt;

==Center-Tapped Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK97.png]]&lt;br /&gt;
&lt;br /&gt;
This five-pin three-port device models a center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;

This is a four-terminal function generator with a sinusoidal wave output, whose frequency is controlled by an input voltage.

In the &amp;quot;frequency vs. voltage&amp;quot; curve, the array &amp;quot;cntl_array&amp;quot; defines voltage values in Volts and the array &amp;quot;freq_array&amp;quot; defines the corresponding frequencies in Hz. &lt;br /&gt;
This function has parameterizable values of low and high peak output voltage.  &lt;br /&gt;

==Current Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17B.png]]&lt;br /&gt;
&lt;br /&gt;
Current source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a current source is its initial transient value.  For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset current. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==Current-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G20.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Current-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the turn-on and turn-off currents in Amperes and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the rest of [[parameters]]. When the current through the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the current through the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==D Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G52.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type flip-flop is a one-bit, edge-triggered storage element which stores data whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). In addition, there are asynchronous set and reset signals, which are independent of the clock. When SET = RESET = 0, the data on the D line is transferred to the output Q on the rising edge of the clock. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

==D Latch==&lt;br /&gt;
&lt;br /&gt;
[[File:G54.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type latch is a one-bit, level-sensitive storage element which outputs the value on the data (D) line whenever the enable (EN) input line is 1 (high). The value on the data line is stored, i.e., held on the output (Q) line whenever the enable (EN) line is 0 (low). In addition, there are set and reset signals, which are independent of the enable line. When SET = RESET = 0, the data on the D line is transferred to the output Q whenever EN = 1. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

==Darlington Pair==&lt;br /&gt;
&lt;br /&gt;
[[File:GK108.png]]&lt;br /&gt;
&lt;br /&gt;
A Darlington pair is a three-pin device that consists of two interconnected BJT transistors of the same type. The collectors of two transistors are connected together to provide the &amp;quot;Collector&amp;quot; pin of the pair. The base of the first BJT acts the &amp;quot;Base&amp;quot; pin of the pair. The emitter of the first BJT is internally connected to the base of the second BJT. The emitter of the second BJT acts as the &amp;quot;Emitter&amp;quot; pin of the pair. There are two types of Darlington pair: NPN and PNP. The parameterized generic Darlington pair also contains a diode connected between the collector and emitter pin as well as two base-emitter resistors, one across each BJT.     &lt;br /&gt;

The digital buffer is a single-input, single-output digital device which produces as output a time-delayed copy of its input. The delays associated with the output rise and fall may be different. The model also posts an input load value (in Farads). The output of this model does NOT, however, respond to the total loading it sees on its output; it will always drive the output strongly with the specified delays. &lt;br /&gt;
&lt;br /&gt;
==Digital Clock==&lt;br /&gt;
&lt;br /&gt;
[[File:G56.png]]&lt;br /&gt;
&lt;br /&gt;
The digital clock provides a periodic pulsing input for many other digital devices. Its parameters include the period and pulse width, both expressed in seconds. The pulse width is the time interval during which the clock's output signal is at its logic high level.&lt;br /&gt;
&lt;br /&gt;
==Digital Frequency Divider Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GK49.png]]&lt;br /&gt;
&lt;br /&gt;
The digital frequency divider is a programmable step-down divider which accepts an arbitrary divisor (div_factor), a duty cycle term (high_cycles), and an initial count value (i_count). The generated output is synchronized to the rising edges of the input signal. Rise delay and fall delay on the outputs may also be specified independently.&lt;br /&gt;

==Digital Input==&lt;br /&gt;
&lt;br /&gt;
[[File:GK46.png]]&lt;br /&gt;
&lt;br /&gt;
The digital input provides the easiest way of defining input data in [[RF.Spice A/D]]. The data is 1-bit and in decimal format by default. You can define multi-bit data as well as a hexadecimal format. The value of the input can be entered either in the device's property dialog or directly in the Schematic Editor using the up and down arrows of the device symbol.&lt;br /&gt;
&lt;br /&gt;
==Digital Oscillator==&lt;br /&gt;
&lt;br /&gt;
[[File:GK41.png]]&lt;br /&gt;
&lt;br /&gt;
The digital oscillator is a mixed-mode device which accepts as input a analog voltage signal. This input is compared to the voltage-to-frequency transfer characteristic specified by the (cntl_array, freq_array) coordinate pairs, and a frequency is obtained which represents a linear interpolation or extrapolation based on those pairs. A digital time-varying signal is then produced with this fundamental frequency. The output waveform, which is the equivalent of a digital clock signal, has rise and fall delays which can be specified independently. In addition, the duty cycle and the phase of the waveform are also variable and can be set by you.&lt;br /&gt;
&lt;br /&gt;
Example SPICE Usage:&lt;br /&gt;
a5 1 8 var_clock&lt;br /&gt;
.model var_clock d_osc cntl_array = [-2 -1 1 2] freq_array = [1e3 1e3 10e3 10e3] duty_cycle = 0.4 init_phase = 180.0  rise_delay = 10e-9 fall_delay=8e-9)&lt;br /&gt;

&lt;br /&gt;
==Digital Output==&lt;br /&gt;
&lt;br /&gt;
[[File:GK47.png]]&lt;br /&gt;
&lt;br /&gt;
The digital output provides the easiest way of displaying output data in [[RF.Spice A/D]]. The data is in decimal format by default. You can display it in the hexadecimal format.&lt;br /&gt;
&lt;br /&gt;
==Digital Probe==&lt;br /&gt;
&lt;br /&gt;
[[File:GK48.png]]&lt;br /&gt;
&lt;br /&gt;
The digital probe is very similar to digital output but does not display the value of the data. It is intended as an output signal designator for transient [[tests]].&lt;br /&gt;
&lt;br /&gt;
==Digital Source==&lt;br /&gt;
&lt;br /&gt;
[[File:GK40.png]]&lt;br /&gt;
&lt;br /&gt;
The digital source provides for straightforward descriptions of digital signal vectors in a tabular format. The device reads input from a table or an input file and, at the times specified, and generates the inputs along with the strengths listed. The data is 1-bit and in decimal format by default. You can define multi-bit data as well as a hexadecimal format. You can also make the data periodic with a specified period in seconds or define an initial delay in seconds. &lt;br /&gt;
&lt;br /&gt;
The format of the input file is as shown below:&lt;br /&gt;
&lt;br /&gt;

==Digital-to-Analog Converter (DAC) Bridge==&lt;br /&gt;
&lt;br /&gt;
[[File:GK43.png]]&lt;br /&gt;
&lt;br /&gt;
The DAC Bridge takes a digital value from a digital node and can only be eiter &amp;amp;quot;0&amp;amp;quot;, &amp;amp;quot;1&amp;amp;quot;,&lt;br /&gt;
or &amp;amp;quot;U&amp;amp;quot;. It then outputs the value &amp;amp;quot;out_low&amp;amp;quot;, &amp;amp;quot;out_high&amp;amp;quot; or &amp;amp;quot;out_udndef&amp;amp;quot;,&lt;br /&gt;
or ramps linearly toward one of these &amp;amp;quot;final&amp;amp;quot; values from its curent analog output level. This&lt;br /&gt;
ramping speed depends on the values of &amp;amp;quot;t_rise&amp;amp;quot; and &amp;amp;quot;t_fall&amp;amp;quot;.&lt;br /&gt;

==Doubly Center-Tapped Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK98.png]]&lt;br /&gt;
&lt;br /&gt;
This six-pin four-port device models a doubly center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;

==Frequency Meter==&lt;br /&gt;
[[File:G114.png]]&lt;br /&gt;
&lt;br /&gt;
The Frequency Meter is a four-pin shunt device that is connected in parallel with an AC source just like a voltmeter and measures the operating frequency of the AC circuit. The input pins are connected across the AC source. The voltage across the output pins is equal to the frequency of the source in Hertz within a scale factor SF. Note that the Frequency Meter is designed to work with a single-tone AC source of unit amplitude. If the amplitude of the source is not one, multiply the SF parameter by the non-unit source amplitude value. The output voltage of the Frequency Meter can be used in conjunction with linear or nonlinear dependent sources to model frequency-dependent quantities.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Model Identifier: fmeter&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Parameters:&lt;br /&gt;
&lt;br /&gt;
The only parameter is the scale factor SF with a default value of 1.0. Set SF = 1e-6 to read out the frequency in MHz. Set SF = 1e-9 to read out the frequency in GHz. Set SF = 6.283185 (2*pi) to read out the angular frequency &amp;amp;omega; in radian/s.  &lt;br /&gt;
&lt;br /&gt;
== Fuse ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK76.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 2-pin interactive current-controlled switch. If the current passing through the fuse is less than a specified threshold current, the switch is closed. If the current exceeds the threshold level, the fuse breaks and remains open thereafter. The device's symbol changes to display its state.   &lt;br /&gt;

&lt;br /&gt;
Ground has a voltage of zero (0) and is used as a reference to compute electrical values in the circuit. &lt;br /&gt;
All circuits &amp;lt;B&amp;gt;must&amp;lt;/B&amp;gt; be grounded to be properly simulated.  There is no limit on the number of grounds&lt;br /&gt;
you may use in a circuit.  All components connected to ground are referenced to a common point and treated&lt;br /&gt;
as linked through ground.&lt;br /&gt;

==Hysteresis Block (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Hysteresis block is a simple buffer stage that provides hysteresis of the output with respect to the&lt;br /&gt;
input.  The in_low and in_high parameter values.  The output values are limited to out_lower_limit and&lt;br /&gt;
out_upper_limit.  The value of \93hyst\94 is added to the in_low and in_high points in order to specify the&lt;br /&gt;
points at which the slope of the hysteresis function would normally change abruptly as the input transitions&lt;br /&gt;
from a low to a high value.  Likewise, the value of \93hyst\94 is subtracted from the in_high and in_low values&lt;br /&gt;
in order to specify the points at which the slope of the hysteresis function would normally change abruptly&lt;br /&gt;
as the input transitions from a high to a low value.  In fact, the slope of the hysteresis function is&lt;br /&gt;
never allowed to change abruptly but is smoothly varied whenever the input_dowmain smoothing parameter&lt;br /&gt;
is set greater than zero.&lt;br /&gt;

==Ideal Center-Tapped Transformer with Push-Pull Input==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR4.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal center-tapped transformer with push-pull input is a five-pin three-port device with two primary input ports and one secondary output port. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P1}{v_S} = \frac{v_P2}{v_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; is the secondary voltage, v&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt; is measured between the top primary pin P1 and the center tap pin, and v&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom primary pin P2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.        &lt;br /&gt;

The ideal center-tapped transformer with push-pull output is a five-pin three-port device with one primary input port and two secondary output ports. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_{S1}} = \frac{v_P}{v_{S2}} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; is the primary voltage, v&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; is measured between the top secondary pin S1 and the center tap pin, and v&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom secondary pin S2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.&lt;br /&gt;

==Ideal Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK106.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device is a very basic and primitive model of a diode as a rectifier or switch. When the voltage across the device's terminals is positive, it acts as a short circuit. When the voltage across the device's terminals is negative, it acts as an open circuit.   &lt;br /&gt;

&lt;br /&gt;
This is a very basic and primitive model of an operational amplifier. It has only one parameter, open loop gain with a default value of 50,000, which is adequate for most cases. The ideal Op-Amp device doesn't require any DC bias voltages. &lt;br /&gt;

==Ideal Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR1.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal transformer is a four-pin two-port device with the following relationship between the voltages and currents at its primary and secondary ports:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_S} = - \frac{i_S}{i_P} = \frac{N_P}{N_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; are the primary voltage, current and number of turns, respectively, and v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; are the secondary voltage, current and number of turns, respectively. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary turns ratio. Note that the ideal transformer model is defined based on controlled sources and does not involve any magnetic physical parameters as opposed to mutual inductors or ferrite core transformer.&lt;br /&gt;
&lt;br /&gt;
==Inductance Meter==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductance Meter measures the total inductance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total inductance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense an inductance value and alter their behavior based upon it. Care must be exercised when connecting an Inductance Meter to the inductors of a circuit. This is due to the fact that inductors are treated by SPICE as current sources. This can cause a problem when an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. &lt;br /&gt;

==Inductive Coupler Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GK99.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductive Coupler Block couples any two existing inductors. This block doesn't have any pins because it doesn't actually represent inductors, only the coupling between them. This is useful if you want to&lt;br /&gt;
couple two inductors that are in different parts of the circuit, or if you want to couple more than two inductors together. In the latter case, use more than one of these, with each one coupling a pair of inductors.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are Inductor1, Inductor2, and k. Inductor1 is the name of first inductor, Inductor2 is the name of the second inductor, and k is the coefficient of coupling, 0 &amp;amp;lt; k &amp;amp;le; 1.&lt;br /&gt;
&lt;br /&gt;
==Inductive Coupling (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G41.png]]&lt;br /&gt;
&lt;br /&gt;
This function is a conceptual model which is used as a building block to create a wide variety of inductive and magnetic circuit models. This function is normally used in&lt;br /&gt;
conjunction with the “core” model, but it can also be used with resistors, hysteresis blocks, etc. to build up systems which mock the behavior of linear and nonlinear components.&lt;br /&gt;
The lcouple takes as an input (on the “l” port) a current. This current value is multiplied by the num_turns value, N, to produce an output value (a voltage value which appears on the&lt;br /&gt;
mmf_out port). The mmf_out acts similar to a magnetomotive force in a magnetic circuit;&lt;br /&gt;
when the lcouple is connected to the “core” model, or to some other resistive device, a current will flow. This current value (which is modulated by whatever the lcouple is&lt;br /&gt;
connected to) is then used by the lcouple to calculate a voltage “seen” at the “l” port. The voltage is a function of the derivative with respect to time of the current value seen at mmf_out.&lt;br /&gt;
&lt;br /&gt;
The most common use for lcouple will be as a building block in the construction of transformer models. To create a transformer with a single input and a single output, you&lt;br /&gt;
would require two lcouple models plus one “core” model. &lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
A1 (1 0) (2 3) lcouple1&lt;br /&gt;
&lt;br /&gt;
.model lcouple1 lcouple ( num_turns = 10 )&lt;br /&gt;

==Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK121.png]]&lt;br /&gt;
&lt;br /&gt;
Inductors are used to store magnetic energy. An inductor's ability to counteract current changes passing through it is called its inductance (L), which is&lt;br /&gt;
measured in Henrys. In a (steady-state) DC analysis, the inductor acts like a short circuit. It is indeed treated as a current source, which can be problematic if an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. The resistor may be of negligible value or one that accounts for the coil resistance of the inductor. In AC and transient analyses, the inductor develops a voltage across it in response to the changing magnetic&lt;br /&gt;
flux within its coil. &lt;br /&gt;
&lt;br /&gt;
An inductor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
v(t) = L*(di(t)/dt) &lt;br /&gt;
&lt;br /&gt;
The inductor's initial condition is optional. It is the initial value of the inductor current in Amperes that flows from node N+ through the inductor to node N-. The only time that the initial current matters is when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked. &lt;br /&gt;
&lt;br /&gt;
An inductor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
v = j &amp;amp;omega; * L * i&lt;br /&gt;
&lt;br /&gt;
All inductor names must begin with L.&lt;br /&gt;

==Inductor with Ferrite Core==&lt;br /&gt;
&lt;br /&gt;
[[File:GK94.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device models a physical inductor with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. Unlike the standard inductor device, you do not specify an inductance value for the inductor with ferrite core. Rather, you specify physical parameters like cross sectional area, core length and number of turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;

== Insulated Gate Bipolar Transistor (IGBT)==&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Insulated Gate Bipolar Transistor (IGBT) device with three pins: Collector(C), Gate (G), and Emitter (E). It is primarily used as a fast electronic switch. The IGBT combines the simple gate-drive characteristics of MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors. The device's model consists of an isolated gate FET for the control input, and a PNP bipolar power transistor as a switch.

==Junction Field Effect Transistor (JFET)==&lt;br /&gt;
&lt;br /&gt;
[[File:G12.png]]&lt;br /&gt;
&lt;br /&gt;
The JFET is the simplest transistor device and has three pins: gate, drain and source. The JFET defaults are based on the Shichman and Hodges FET model. This is a square-law device because of the expression relating the drain current to the gate-to-source voltage: &lt;br /&gt;
Idrain=*(VGS-Vthreshold)2.  In real JFETs, near the saturation point, the drain currents vary with the drain voltages. This can be modeled by the following formula:  Idrain=*(VGS-VTO)2*(1+*VDS), which yields an increasing&lt;br /&gt;
drain current for increasing values of VDS.&lt;br /&gt;
&lt;br /&gt;
The gate-to-source and gate-to-drain junctions each have a nonlinear capacitor.  The zero-bias capacitance value is selected for each junction.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

The CCCS is a current source whose current is directly proportional to the current across a controlling Ammeter or a voltage source. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the current gain, which has a default value of one. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the current gain.   &lt;br /&gt;

==Lossless Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G21.png]]&lt;br /&gt;
&lt;br /&gt;
The lossless transmission line is a four-pin two-port device that models only one propagating mode of an ideal transmission line.  When using this SPICE model, should all four nodes of the actual circuit be distinct, two modes may be activated, and this device would be insufficient for that purpose. To circumvent this potential problem, two transmission line devices would be required. Due to the implementation details, you may produce more accurate simulation results with a lossy transmission line device with zero loss.&lt;br /&gt;
&lt;br /&gt;
Optional initial condition parameters are the voltage and current at each of the transmission line ports.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are Z0, TD, F, NL, IC, described below:&lt;br /&gt;

==Lossy Transmission Line==&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The lossy transmission line is a four-pin two-port convolution model for uniform constant-parameter distributed lines. MNAME is the process model name, which&lt;br /&gt;
includes a set of pre-specified options as described below.&lt;br /&gt;

The RLC (uniform transmission line with series loss only), RC (uniform RC line), LC (lossless transmission&lt;br /&gt;
line), and RG (distributed series resistance and parallel conductance only) lines have been implemented. &lt;br /&gt;
The length (LEN) must be given.  COMPACTREL and COMPACTABS control the compaction of past history values&lt;br /&gt;
used in convolution.  Larger values for these lower accuracy but improve speed.  These are used with the&lt;br /&gt;
TRYTOCOMPACT option. &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Magnetic Core (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G42.png]]&lt;br /&gt;
&lt;br /&gt;
This device is used as a building block to create a wide variety of inductive and magnetic circuit models. It is almost always to be used in conjunction with the &amp;quot;lcouple&amp;quot; model to build up systems which simulate the behavior of linear and nonlinear magnetic components. There are two fundamental modes of operation for the core model. These are the &amp;quot;PWL&amp;quot; mode (which is the default and most&lt;br /&gt;
likely to be of use to you) and the &amp;quot;Hysteresis&amp;quot; mode.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;PWL Mode (mode = 1)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the PWL mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf) value. This value is divided by the total effective length of the core to produce a value for the Magnetic Field Intensity, H, which is then used to find the corresponding Flux Density, B, using the piecewise linear relationship described by you in the H_array / B_array coordinate pairs. B is then multiplied by the cross-sectional area of the core to find the Flux value, which is output as a current. The pertinent mathematical equations are:&lt;br /&gt;
&lt;br /&gt;
H = mmf / L, where L = Length (in apmere-turns/meter)&lt;br /&gt;
&lt;br /&gt;
B = f(H)&lt;br /&gt;
&lt;br /&gt;
&amp;amp;Phi; = B * A, where A = Area&lt;br /&gt;
&lt;br /&gt;
The B value is derived from a piecewise linear transfer function described to the model by the H_array and B_array coordinate pairs.  This transfer function does not include hysteretic effects; for that, you would need to substitute a HYST model for the core. The magnetic flux value &amp;amp;Phi; in turn is used by the &amp;quot;lcouple&amp;quot;&lt;br /&gt;
code model to obtain a value for the voltage reflected back across its terminals to the driving electrical circuit.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Hysteresis Mode (mode = 2)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the Hysteresis mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf)&lt;br /&gt;
value.  This value is used as input to the equivalent of a hysteresis code model block.  The parameters&lt;br /&gt;
defining the input low and high values, the output low and high values, and the amount of hysteresis are&lt;br /&gt;
as in that model. The output from this mode, as in PWL mode, is a current value which is seen across the magnetic core port.&lt;br /&gt;
&lt;br /&gt;
One final note to be made about the two core models is that certain parameters are specific to one or the other.  In particular, the in_low, in_high, out_lower_limit, out_upper_limit, and hysteresis parameters are not available in PWL mode. Likewise, the H_array, B_array, area, ad length values are unavailable&lt;br /&gt;
in Hysteresis mode.  The input_domain and fraction parameters are common to both modes (though their behavior is somewhat different; for explanation of the input_domain and fraction values for the Hysteresis mode, please refer to the Hysteresis Block discussion.&lt;br /&gt;

[[File:G16.png]]&lt;br /&gt;
&lt;br /&gt;
The marker serves several purposes:&lt;br /&gt;
&lt;br /&gt;
* It can appear as a default plot in simulations if the &amp;amp;quot;Voltage Probe&amp;amp;quot; box is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to set the initial voltage or voltage guess at the node it is connected to.&lt;br /&gt;
&lt;br /&gt;
* It can be used as a port for a subcircuit when you choose the checkbox labeled &amp;quot;Use as Subcircuit Port&amp;quot; is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to explicitly set a node number in place of the arbitrarily assigned node number by the program. In this case, make sure the &amp;amp;quot;Set Node Index&amp;amp;quot; box is checked.  Otherwise, it will act as just a voltage probe.&lt;br /&gt;
&lt;br /&gt;
* It can be used to connect different parts of a circuit in place of wires. To use markers as virtual connectors, place them at points where wires would otherwise connect. Then set the Part Title of the two (or more) markers to the same name, and they will act as a single circuit node.&lt;br /&gt;

==MESFET==&lt;br /&gt;
&lt;br /&gt;
[[File:G14.png]]&lt;br /&gt;
&lt;br /&gt;
The MESFET is a Schottky-barrier gate FET with six times greater electron mobility than silicon.  MESFETs are important devices for creating high frequency circuits. They function by creating a potential barrier between the gate and the channel when the metal gate&lt;br /&gt;
contacts the gallium-arsenide substrate. Electron velocity saturates for fields approximately ten times lower than with silicon.  The Curtice model includes linear and saturated operation.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

&lt;br /&gt;
The MOSFET is an active device that has up to 4 pins.  The three standard pins are gate, drain, and source.  These are given in the default symbol.  The bulk node, which is grounded by default, is the fourth pin.  The MOSFET with the bulk is named mos_n_lvl1_4 (the lvl1 is for level 1, the n for nmos, and the 4 for 4 pins.)&lt;br /&gt;
&lt;br /&gt;
The standard [[parameters]] are L, W, AD, AS, PD, PS, NRD, NRS, OFF, IC, and T.  They are described below:&lt;br /&gt;

There are five different default models: square-law I-V characteristic, analytical, semi-empirical, and BSIM and BSIM2 (Berkeley Short-channel IGFET Model), which include second-order effects such as channel-length&lt;br /&gt;
modulation, subthreshold conduction, scattering-limited velocity saturation, small-size effects, and charge-controlled capacitance.  The process parameter LEVEL specifies which of the models is chosen as indicated below:&lt;br /&gt;

&lt;br /&gt;
The mutual inductors device is a pair of inductors that are coupled to each other.  L1 and L2 are the names of two inductors. You have to specify the inductance of inductor L1, the inductance of inductor L2, the initial current through each, and the coupling coefficient k, 0 &amp;amp;le; k &amp;amp;le; 1. The mutual inductance M expressed in units of H can be calculated using the following definition:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; k = \frac{M}{\sqrt{L_1 L_2}} &amp;lt;/math&amp;gt;&lt;br /&gt;

==Non-Ideal Current Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK104.png]]&lt;br /&gt;
&lt;br /&gt;
This 8-pin device models a non-ideal lossy current transformer. Its model consists of an ideal transformer with more secondary turns than primary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. on each side of the internal ideal transformer, there is a series leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, followed by a shunt winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a series winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, which connects to the exterior positive pin on that side. The inter-winding resistance R&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the negative pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance. &lt;br /&gt;

&lt;br /&gt;
This 2-pin device is a basic simplified model of a diode as a rectifier or switch. When forward-biased, it acts as a low-valued voltage source. When reverse-biased, it acts as an open circuit until the reverse voltage exceeds the specified breakdown voltage. Then it acts as a high-valued voltage source of the reverse polarity. &lt;br /&gt;

&lt;br /&gt;
This 8-pin device models a non-ideal lossy voltage transformer. Its model consists of an ideal transformer with more primary turns than secondary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. There are series combinations of a winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; on the primary and secondary sides. These are connected between the positive interior and exterior pins on each side. There are also two shunt branches at the inputs of the primary and secondary sides (connected between the positive and negative exterior pins), each consisting of a distributed turn-to-turn winding resistance RDC&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; in series with a distributed turn-to-turn winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;. The inter-winding capacitance CWW&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the positive pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance.  &lt;br /&gt;

==Nonlinear Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK89.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear capacitor model allows the capacitor to be described by an arbitrary relationship between the capacitor's charge Q and the voltage V across the capacitor. In other words, Q = f(V). The nonlinear capacitance is then defined as C(V) = dQ/dV. You need to define the charge Q by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ C_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear capacitor, where Q = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, C = C(V) = dQ/dV = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Conductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK88.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear conductor model allows the conductor to be described by an arbitrary relationship between the conductor's current I and the voltage V across the conductor. In other words, I = f(V). The nonlinear conductance is then defined as G(V) = dI/dV. You need to define the current I by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ G_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear conductor, where I = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, G = G(V) = dI/dV = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Dependent Sources==&lt;br /&gt;
&lt;br /&gt;
[[File:G18.png]]&lt;br /&gt;
&lt;br /&gt;
Nonlinear dependent (arbitrary) sources use an equation or mathematical expression to describe their behavior. One and only one of the two forms: V=&amp;amp;lt;expr&amp;amp;gt; or  I=&amp;amp;lt;expr&amp;amp;gt; must be given.&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; v = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; i = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Examples: &lt;br /&gt;
&lt;br /&gt;
v = I(v1) + 3* I(v2)&lt;br /&gt;
&lt;br /&gt;
I = v(i1) + 3* v(2) + 5 * v(3) ^2&lt;br /&gt;
&lt;br /&gt;
The first example is a current-controlled voltage source.  The v on the left side of the equation&lt;br /&gt;
indicates that it is a voltage source.  I(v1) and I(v2) are the currents through voltage sources named v1 and v2, respectively.&lt;br /&gt;
&lt;br /&gt;
The second example is a voltage-controlled current source.  v(2) and v(3) represents the voltages at nodes 2 and 3, respectively, and v(i1) represents the voltage across a current source named i1.&lt;br /&gt;
&lt;br /&gt;
The following mathematical functions defined for real variables can be used in the expressions:&lt;br /&gt;
&lt;br /&gt;
abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), atanh(x), cos(x), cosh(x), exp(x), ln(x), log(x), max(x,y), min(x,y), pwr(x,y), pwrs(x,y), sgn(x), sin(x), sinh(x), sqrt(x), tan(x), tanh(x), u(x), uramp(x).&lt;br /&gt;
&lt;br /&gt;
The function &amp;amp;quot;sgn&amp;amp;quot; is the signum function and its value is 1 if the argument is positive or zero and -1 if the argument is negative. &lt;br /&gt;
The function &amp;amp;quot;u(x)&amp;amp;quot; is the unit step and &amp;amp;quot;uramp(x)&amp;amp;quot; is the integral of the unit step.  The&lt;br /&gt;
unit step is one if its argument is greater than zero and zero if its argument is less than zero.  The&lt;br /&gt;
ramp function (uramp) is 0 for argument values less than zero and equal to the argument for argument values&lt;br /&gt;
greater than zero.&lt;br /&gt;
&lt;br /&gt;
The following operators are permissible:  +, -, *, /, and ^.&lt;br /&gt;
&lt;br /&gt;
The power functions have equivalent expressions: pwr(x,y) = x^y and pwrs(x,y) = sgn(x)*abs(x)^y.&lt;br /&gt;
&lt;br /&gt;
Two constants can also be used in expressions: pi = 3.1415926 and e = 2.7182818.&lt;br /&gt;
&lt;br /&gt;
There is a conditional function with the syntax IF(Condition, Expression1, Expression2). If &amp;quot;Condition&amp;quot; is met, then the return value of the function is Expression1; otherwise, it is Expression2. An example of this type of function is IF(v(1)&amp;gt;=0,1,-1), which is equivalent to sgn(v(1)). &lt;br /&gt;
&lt;br /&gt;
To get time into an expression, integrate the current from a constant current source with a capacitor&lt;br /&gt;
and use the voltage across the capacitor.&lt;br /&gt;
&lt;br /&gt;
Note: All the functions and expressions are case-insensitive.&lt;br /&gt;
&lt;br /&gt;
==Nonlinear Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK90.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear inductor model allows the inductor to be described by an arbitrary relationship between the inductor's magnetic flux &amp;amp;Phi; and the current I flowing through the inductor . In other words, &amp;amp;Phi;  = f(I). The nonlinear inductance is then defined as L(I) = d&amp;amp;Phi;/dI. You need to define the flux &amp;amp;Phi; by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ L_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear inductor, where &amp;amp;Phi; = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, L = L(I) = d&amp;amp;Phi;/dI = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.  &lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(i(vx))^2.&lt;br /&gt;

==Nonlinear Resistor==&lt;br /&gt;

[[File:GK87.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear resistor model allows the resistor to be described by an arbitrary relationship between the voltage V across the resistor and its current I. In other words, V = f(I). The nonlinear resistance is then defined as R(I) = dV/dI. You need to define the voltage V by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ R_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear resistor, where V = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, R = R(I) = dV/dI = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 10*(i(vx))^2.&lt;br /&gt;

==Operational Amplifier (Op-Amp)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK105.png]]&lt;br /&gt;
&lt;br /&gt;
This three-pin device models a parameterized operational amplifier with a very high voltage gain, a very high input impedance and a very low output impedance. The behavioral model of the parameterized Op-Amp device is based on the algorithm found in the book &amp;lt;B&amp;gt;Macromodeling with Spice&amp;lt;/B&amp;gt;,&lt;br /&gt;
authored by Connelly &amp;amp;amp; Choi, published by Prentice Hall. The default parameters are those of the 741 Op-Amp. This device doesn't require external DC bias voltage sources. Its positive and negative DC bias voltages are specified as its parameters. Sometimes the simulation doesn't converge if there is no DC path from the output of the Op-Amp to the ground.&lt;br /&gt;

== Optocoupler ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK115.png]]&lt;br /&gt;
&lt;br /&gt;
This is a five-pin parameterized optocoupler device. Its model consists of an ideal diode device in series with an Ohmic resistance connected between the Anode (A) and Cathode (K) pins together with a bipolar junction transistor device with three accessible pins, Collector (C), Base (B) and Emitter (E). A current-controlled current source is connected between base and collector of the BJT, whose current is controlled by the current passing through the diode. The proportionality constant is twice the specified value of the current transfer ratio (ctr) parameter. &lt;br /&gt;
&lt;br /&gt;
You can change or enhance the models of the diode and BJT by adding more parameters. To do so, you have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

[[File:GK113.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 4-pin parameterized photodiode device. A pair of pins, Anode (A) and Cathode (K), represent the physical terminals of the photodiode. The photodiode model connected between the anode and cathode pins consists of the parallel connection of an ideal diode, a dark current source, a noise current source, a current-controlled current source, a diode capacitance, a shunt resistance altogether with a series resistance.  &lt;br /&gt;
&lt;br /&gt;
Another pair of pins IS+ and IS- act as an ammeter that must be inserted in a control circuit. The current passing through this ammeter controls the current of the photodiode. The default proportionality constant is unity. The controlling current is typically a function of light intensity incident on the surface of the photodiode.    &lt;br /&gt;

==Piecewise Linear (PWL) Controlled Source==&lt;br /&gt;
&lt;br /&gt;
[[File:GL49.png]]&lt;br /&gt;
&lt;br /&gt;
The Piecewise Linear (PWL) Controlled Source is a single-input and single-output function generator whose output is not necessarily&lt;br /&gt;
linear for all input values. Instead, it follows an I/O relationship that is specified by the x_array and y_array coordinates. The x_array and y_array values represent vectors of coordinate points on the x and y axes, respectively. The x_array values are progressively increasing input coordinate points, and the associated y_array values represent the outputs at those points.  There may be as few as two pairs specified, or as many as memory and simulation speed allow.&lt;br /&gt;
&lt;br /&gt;
In order to fully specify outputs for values of Vin outside of the bounds of the PWL function, the PWL&lt;br /&gt;
controlled source model extends the slope found between the lowest two coordinate pairs and the highest&lt;br /&gt;
two coordinate pairs.  This has the effect of making the transfer function completely linear for Vin&lt;br /&gt;
less than x_array[0] and Vin greater than x_array[n]. It also has the potentially subtle effect of unrealistically&lt;br /&gt;
causing an output to reach a very large or small value for large inputs. You should thus keep in mind&lt;br /&gt;
that the PWL Source does not inherently provide a limiting capability.&lt;br /&gt;
&lt;br /&gt;
In order to diminish the potential for divergence of simulations when using the PWL block, a form&lt;br /&gt;
of smoothing around the x_array and y_array coordinate points is necessary.  This is due to the iterative&lt;br /&gt;
nature of the simulator and its reliance on smooth first derivatives of  transfer functions in order to&lt;br /&gt;
arrive at a matrix solution.  Consequently, the two parameters &amp;quot;input_domain&amp;quot; and &amp;quot;fraction&amp;quot; are included&lt;br /&gt;
to allow you some control over the amount and nature o the smoothing performed.&lt;br /&gt;
&lt;br /&gt;
Fraction is a switch that is either TRUE or FALSE.  When TRUE (the default setting), the simulator assumes&lt;br /&gt;
that the specified input_domain value is to be interpreted as a fractional figure.  Otherwise, it is interpreted&lt;br /&gt;
as an absolute value.  Thus, if fraction = TRUE and input_domain = 0.10, the simulator assumes that the smoothing&lt;br /&gt;
radius about each coordinate point is to be set equal to 10% of the length of either the x_array segment&lt;br /&gt;
above each coordinate point, or the x_array segment below each coordinate point. The specific segment&lt;br /&gt;
length chosen will be the smallest of these two for each coordinate point.&lt;br /&gt;
&lt;br /&gt;
If fraction = FALSE and input_domain = 0.10, then the simulator will begin smoothing the transfer function at 0.10&lt;br /&gt;
volts (or amperes) below each x_array coordinate and will continue the smoothing process for another 0.10&lt;br /&gt;
volts (or amperes) above each x_array coordinate point.&lt;br /&gt;

== Programmable Unijunction Transistor (PUT)==&lt;br /&gt;

[[File:GK112.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Programmable Unijunction Transistor (PUT) device with three pins: Base 1 (B1), Base 2 (B2) and Emitter (E). It is biased with a positive voltage between the two bases. This device has a unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. It exhibits a negative resistance characteristic and so it can be employed as an oscillator. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively.

&lt;br /&gt;
Resistors are passive devices that dissipate power. Their resistance value varies depending on how much power they can dissipate and is measured&lt;br /&gt;
in Ohms.  The transient, DC and AC behaviors of a resistor are all described by the same equation:&lt;br /&gt;
&lt;br /&gt;
v = R * i&lt;br /&gt;
&lt;br /&gt;
where v is the voltage across the resistor, i is the current passing through the resistor, and R is the resistance. The value of R must be nonzero. &lt;br /&gt;
&lt;br /&gt;
All resistor names must begin with R.&lt;br /&gt;

==Schottky Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK80.png]]&lt;br /&gt;
&lt;br /&gt;
The Schottky diode has the same model as the generic diode with a nonzero transit time (tt), a nonzero junction capacitance (cjo) and a typically larger saturation current (is), a lower junction potential (vj) and a smaller grading coefficient (m).   &lt;br /&gt;
&lt;br /&gt;
==Semiconducting Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK83.png]]&lt;br /&gt;
&lt;br /&gt;
This is the more general form of the Capacitor model and allows for the calculation of the actual capacitance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
CXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;IC=VAL&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it defines the capacitance. If MNAME is specified, then the capacitance is calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. Either VALUE or MNAME, LENGTH, and WIDTH may be specified, but not both sets. The optional initial condition &amp;quot;IC&amp;quot; is the initial voltage across the capacitor for transient simulations.&lt;br /&gt;
&lt;br /&gt;
The capacitance is computed as:&lt;br /&gt;
&lt;br /&gt;
CAP = CJ * (LENGTH - NARROW) * (WIDTH - NARROW)+ 2 * CJSW * (LENGTH + WIDTH - 2NARROW) * CAP&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the capacitor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit CJ, CJSW, NARROW, DEFW, and CAP.&lt;br /&gt;

&lt;br /&gt;
This is the more general form of the resistor model and allows for the modeling of temperature effects and for the calculation of the actual resistance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
RXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;TEMP=T&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it overrides the geometric information and defines the resistance. If MNAME is specified, then the resistance may be calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. The (optional) TEMP value is the temperature at which this device is to operate, and overrides the temperature specification in the SPICE Options Dialog. &lt;br /&gt;
&lt;br /&gt;
The resistance is computed as:&lt;br /&gt;
&lt;br /&gt;
R(T0) = (RSH) * [(L - NARROW) / (W - NARROW)] * RES&lt;br /&gt;
&lt;br /&gt;
R(T) = R(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the resistor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit TC1, TC2, RSH, RES, etc.&lt;br /&gt;

== Triac Thyristor ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK110.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin bidirectional thyristor device that conducts current in either direction when triggered. A thyristor is analogous to a relay in that a small voltage and current can control a much larger voltage and current. The triac has two anode pins termed Main Terminal 1 (MT1) and Main Terminal 2 (MT2) and a Gate (G) pin. In order to create a triggering current for a triac, either a positive or negative voltage can be applied to the gate. Once triggered, the thyristor continues to conduct, even if the gate current ceases, until the main current drops below a certain level called the holding current. The device's model involves two NPN BJT transistors and two PNP BJT transistors. The forward beta parameters of the NPN and PNP transistors are set equal to 20 and 5, respectively. To changes these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.&lt;br /&gt;

==Uniform RC Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G23.png]]&lt;br /&gt;
&lt;br /&gt;
The standard parameters are L, and N.  They are described below:&lt;br /&gt;
&lt;br /&gt;
Two of the nodes are the element nodes connected by the RC line.  The third is the node to which the capacitances&lt;br /&gt;
are connected.  L is the length of the RC line in meters.  N is the number of lumped segments to use in&lt;br /&gt;
modeling the RC line.&lt;br /&gt;
&lt;br /&gt;
This device is derived from a model proposed by Gertzberrg.  It expands the URC line into a network of&lt;br /&gt;
lumped RC segments with internally generated nodes.  These segments increase toward the middle of the&lt;br /&gt;
URC line in a geometric progression with K as the proportionality constant.&lt;br /&gt;
&lt;br /&gt;
The URC line is made up entirely of resistor and capacitor segments, unless the ISPERL parameter has a&lt;br /&gt;
non-zero value.  In this case, capacitors are replaced by reverse biased diodes with an equivalent zero-bias&lt;br /&gt;
junction capacitance, a saturation current of ISPERL amps per meter of transmission line, and optional&lt;br /&gt;
series resistance of RSPERL ohms per meter. &lt;br /&gt;

==Voltage-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G19.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Voltage-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Voltmeter or controlling voltage nodes, as well as the turn-on and turn-off voltages in Volts and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the rest of [[parameters]]. When the voltage across the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the voltage across the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Voltage Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17A.png]]&lt;br /&gt;
&lt;br /&gt;
A voltage source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a voltage source is its initial transient value. For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset voltage. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==XSpice Devices and their models==&lt;br /&gt;
&lt;br /&gt;
XSpice devices have the following form:&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 4pt  0pt  1px  0pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;

&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
e.g., A2 1  2  transfer_function&lt;br /&gt;
&lt;br /&gt;
Note that XSpice devices must start with the &amp;amp;quot;A&amp;amp;quot; designation, much as a resistor starts with&lt;br /&gt;
an &amp;amp;quot;R&amp;amp;quot;.  Some devices will have grouped (or vector) pins and are designated by being placed&lt;br /&gt;
inside square brackets.  In the example shown below, the 1 and 2 pins are grouped.  Pin 3 is not.  &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  0pt ; text-indent: 36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
A1 [1   2]  3 summer &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Some models will have voltage differential pairs of pins and will be denoted by a %vd( ).  In the following&lt;br /&gt;
example pins 1 and 4 are differential pairs, as well as pins 2 and 3.  Differential pairs must go between&lt;br /&gt;
parentheses (). &lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  0pt ; text-indent: 36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
A1 %vd(1   4)   %vd(2   3)  triangle &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Refer to individual devices for more information.&lt;br /&gt;
&lt;br /&gt;
Each XSpice device will also have a model associated with it.  Each model will have the following form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
.model &amp;amp;lt;model_name&amp;amp;gt; &amp;amp;lt;model_identifier&amp;amp;gt; {&amp;amp;lt;pname1 = pval1&amp;amp;gt;} {&amp;amp;lt;pname2 = pval2&amp;amp;gt;} &lt;br /&gt;
...&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
e.g., .model transfer_function s_xfer  in_offset = 0.0  gain = 1.0&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Model_name refers to the name given in the device line.  Model_identifier is an internal designation and&lt;br /&gt;
must be of an existing designation  Refer to each device's example for the correct designation. &lt;br /&gt;
&lt;br /&gt;
Parameter values are optional.  If they aren't specified, then the default will be used.  Some devices&lt;br /&gt;
have parameters that require a value and must be specified.  Refer to individual devices for any required parameters.&lt;br /&gt;
&lt;br /&gt;
==Zener Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:G10.png]]&lt;br /&gt;
&lt;br /&gt;
The Zener Diode models the DC characteristics of most zeners. Since most data sheets for zener diodes do&lt;br /&gt;
not give detailed characteristics in the forward region, only a single point defines the forward characteristicThe&lt;br /&gt;
saturation current refers to the relatively constant reverse current that is produced when the voltage&lt;br /&gt;
across the zener is negative, but breakdown has not been reached.  The reverse leakage current determines&lt;br /&gt;
the slight increase in reverse current as the voltage across the zener becomes more negative.  It is modeled&lt;br /&gt;
as a resistance parallel to the zener with value v_breakdown / i_rev.&lt;br /&gt;
&lt;br /&gt;
Note that the limt_switch parameter engages an internal limiting function for the zener.  This can, in&lt;br /&gt;
some cases, prevent the simulator from converging to an unrealistic solution if the voltage across or&lt;br /&gt;
current into the device is excessive.  If use of this feature fails to yield acceptable results, the convlimit&lt;br /&gt;
option should be tried (add the following statement to the SPICE input deck:  .options convlimit)&lt;br /&gt;
&lt;br /&gt;

==Analog-to-Digital Converter (ADC) Bridge==&lt;br /&gt;
[[File:GK42.png]]&lt;br /&gt;
&lt;br /&gt;
The ADC Bridge takes an analog value from an analog node and may be in the form of a voltage or current.&lt;br /&gt;
If the input is less than or equal to &amp;amp;quot;in_low&amp;amp;quot;, then a digital &amp;amp;quot;0&amp;amp;quot; is generated. If&lt;br /&gt;
the input is greater than or equal to &amp;amp;quot;in_high&amp;amp;quot;, a digital &amp;amp;quot;1&amp;amp;quot; is generated. Otherwise,&lt;br /&gt;
a digital &amp;amp;quot;UNKNOWN&amp;amp;quot; is the output value. Unlike the DAC Bridge, ramping or delay is not applicable.&lt;br /&gt;
Rather, the continuous ramping of the input provides for any associated delays in the digitized signal.&lt;br /&gt;
&lt;br /&gt;
This model also posts an input load value based on the parameter input_load.&lt;br /&gt;

==Bipolar Junction Transistor (BJT)==&lt;br /&gt;
[[File:G11.png]]&lt;br /&gt;
&lt;br /&gt;
The BJT is an active device which has up to 4 pins.  The three standard pins are base, emitter, and collector.  These are given in the default symbol.  The substrate, which is grounded by default, is the fourth pin.  To use the BJT with the substrate, create a new 4-pin BJT using the Device Editor and Symbol Editor.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|AREA||area factor (optional) (If not specified, the default value is 1.0.)&lt;br /&gt;
|-&lt;br /&gt;
|OFF||initial condition for the DC analysis (optional)&lt;br /&gt;
|-&lt;br /&gt;
|IC||initial condition (optional) (Used when a transient analysis is desired, which starts from other than the quiescent operating point.)&lt;br /&gt;
|-&lt;br /&gt;
|T||operating temperature of the device (optional)&lt;br /&gt;
|-&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Area factor scales the model parameters RE and RC.  IC VBE is the initial voltage from base emitter. IC VCE is the initial voltage from collector to emitter.  TEMP is the overriding temperature. These parameters are based on the Gummel and Poon integral-charge model.  If these parameters are not specified, then it will reduce to the simpler Ebers-Moll model. &lt;br /&gt;
&lt;br /&gt;
The process model is mandatory for the BJT.  Descriptions of the process model parameters are given in the following table:&lt;br /&gt;

==Capacitance Meter==&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Capacitance Meter measures the total capacitance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total capacitance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense a capacitance value and alter their behavior based upon it.&lt;br /&gt;

&lt;br /&gt;
==Capacitor==&lt;br /&gt;
[[File:GK120.png]]&lt;br /&gt;
&lt;br /&gt;
Capacitors are used to store electrical energy.  They can filter or remove AC signals or block DC current without disrupting AC signals. A capacitor's ability to store energy is termed capacitance and is measured in Farads, with values from pF to mF. The only time current flows through a capacitor is when the charge is collected on, or is removed from, its parallel plates. This means that the voltage across the capacitor is changing, which doesn't conform to DC analysis. In a physical circuit, there is a transition stage during which capacitors charge up to their final values. The result is the same as if these capacitors did not exist and the connections to them were left dangling. In other words, in a (steady-state) DC analysis, a capacitor behaves like an open circuit. Therefore, it is important that no section of the circuit is isolated from the capacitors. Every circuit node needs some path for DC current to the ground.&lt;br /&gt;
&lt;br /&gt;
A capacitor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
i(t) = C * (dv(t)/dt)&lt;br /&gt;
&lt;br /&gt;
Its initial voltage is only important when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked.&lt;br /&gt;
&lt;br /&gt;
An capacitor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
i = j ω * C * v &lt;br /&gt;
&lt;br /&gt;
All capacitor names must begin with C. &lt;br /&gt;

[[RF.Spice A/D]] provides three types of capacitors: simple, user-defined (or real) and semiconductor. The standard capacitor parameters are N+, N-, VALUE, and IC. In a simple capacitor, VALUE must&lt;br /&gt;
be specified for the capacitance in Farads. IC is the (optional) initial condition for the capacitor voltage.&lt;br /&gt;

==Center-Tapped Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK97.png]]&lt;br /&gt;
&lt;br /&gt;
This five-pin three-port device models a center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;

==Current Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17B.png]]&lt;br /&gt;
&lt;br /&gt;
Current source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a current source is its initial transient value.  For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset current. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==Current-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G20.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Current-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the turn-on and turn-off currents in Amperes and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the rest of [[parameters]]. When the current through the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the current through the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Darlington Pair==&lt;br /&gt;
&lt;br /&gt;
[[File:GK108.png]]&lt;br /&gt;
&lt;br /&gt;
A Darlington pair is a three-pin device that consists of two interconnected BJT transistors of the same type. The collectors of two transistors are connected together to provide the &amp;quot;Collector&amp;quot; pin of the pair. The base of the first BJT acts the &amp;quot;Base&amp;quot; pin of the pair. The emitter of the first BJT is internally connected to the base of the second BJT. The emitter of the second BJT acts as the &amp;quot;Emitter&amp;quot; pin of the pair. There are two types of Darlington pair: NPN and PNP. The parameterized generic Darlington pair also contains a diode connected between the collector and emitter pin as well as two base-emitter resistors, one across each BJT.     &lt;br /&gt;

==D Flip-Flop==&lt;br /&gt;
&lt;br /&gt;
[[File:G52.png]]&lt;br /&gt;
&lt;br /&gt;
The digital D-type flip-flop is a one-bit, edge-triggered storage element which stores data whenever the clock (CLK) input line transitions from 0 (low) to 1 (high). In addition, there are asynchronous set and reset signals, which are independent of the clock. When SET = RESET = 0, the data on the D line is transferred to the output Q on the rising edge of the clock. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

&lt;br /&gt;
The digital D-type latch is a one-bit, level-sensitive storage element which outputs the value on the data (D) line whenever the enable (EN) input line is 1 (high). The value on the data line is stored, i.e., held on the output (Q) line whenever the enable (EN) line is 0 (low). In addition, there are set and reset signals, which are independent of the enable line. When SET = RESET = 0, the data on the D line is transferred to the output Q whenever EN = 1. The combination SET = 1 and RESET = 0, causes Q = 1. The combination SET = 0 and RESET = 1 causes Q = 0. The combination SET = RESET = 1 is illegal and is resolved by setting both outputs Q and Q_bar to 1.&lt;br /&gt;

==Frequency Meter==&lt;br /&gt;
[[File:G114.png]]&lt;br /&gt;
&lt;br /&gt;
The Frequency Meter is a four-pin shunt device that is connected in parallel with an AC source just like a voltmeter and measures the operating frequency of the AC circuit. The input pins are connected across the AC source. The voltage across the output pins is equal to the frequency of the source in Hertz within a scale factor SF. Note that the Frequency Meter is designed to work with a single-tone AC source of unit amplitude. If the amplitude of the source is not one, multiply the SF parameter by the non-unit source amplitude value. The output voltage of the Frequency Meter can be used in conjunction with linear or nonlinear dependent sources to model frequency-dependent quantities.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Model Identifier: fmeter&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Parameters:&lt;br /&gt;
&lt;br /&gt;
The only parameter is the scale factor SF with a default value of 1.0. Set SF = 1e-6 to read out the frequency in MHz. Set SF = 1e-9 to read out the frequency in GHz. Set SF = 6.283185 (2*pi) to read out the angular frequency &amp;amp;omega; in radian/s.  &lt;br /&gt;
&lt;br /&gt;
== Fuse ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK76.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 2-pin interactive current-controlled switch. If the current passing through the fuse is less than a specified threshold current, the switch is closed. If the current exceeds the threshold level, the fuse breaks and remains open thereafter. The device's symbol changes to display its state.   &lt;br /&gt;

&lt;br /&gt;
[[File:G15.png]]&lt;br /&gt;
&lt;br /&gt;
Ground has a voltage of zero (0) and is used as a reference to compute electrical values in the circuit. &lt;br /&gt;
All circuits &amp;lt;B&amp;gt;must&amp;lt;/B&amp;gt; be grounded to be properly simulated.  There is no limit on the number of grounds&lt;br /&gt;
you may use in a circuit.  All components connected to ground are referenced to a common point and treated&lt;br /&gt;
as linked through ground.&lt;br /&gt;
&lt;br /&gt;
==Hysteresis Block (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Hysteresis block is a simple buffer stage that provides hysteresis of the output with respect to the&lt;br /&gt;
input.  The in_low and in_high parameter values.  The output values are limited to out_lower_limit and&lt;br /&gt;
out_upper_limit.  The value of \93hyst\94 is added to the in_low and in_high points in order to specify the&lt;br /&gt;
points at which the slope of the hysteresis function would normally change abruptly as the input transitions&lt;br /&gt;
from a low to a high value.  Likewise, the value of \93hyst\94 is subtracted from the in_high and in_low values&lt;br /&gt;
in order to specify the points at which the slope of the hysteresis function would normally change abruptly&lt;br /&gt;
as the input transitions from a high to a low value.  In fact, the slope of the hysteresis function is&lt;br /&gt;
never allowed to change abruptly but is smoothly varied whenever the input_dowmain smoothing parameter&lt;br /&gt;
is set greater than zero.&lt;br /&gt;

==Ideal Center-Tapped Transformer with Push-Pull Input==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR4.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal center-tapped transformer with push-pull input is a five-pin three-port device with two primary input ports and one secondary output port. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P1}{v_S} = \frac{v_P2}{v_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; is the secondary voltage, v&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt; is measured between the top primary pin P1 and the center tap pin, and v&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom primary pin P2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.        &lt;br /&gt;
&lt;br /&gt;
==Ideal Center-Tapped Transformer with Push-Pull Output==&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The ideal center-tapped transformer with push-pull output is a five-pin three-port device with one primary input port and two secondary output ports. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_{S1}} = \frac{v_P}{v_{S2}} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; is the primary voltage, v&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; is measured between the top secondary pin S1 and the center tap pin, and v&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom secondary pin S2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.&lt;br /&gt;
&lt;br /&gt;
==Ideal Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK106.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device is a very basic and primitive model of a diode as a rectifier or switch. When the voltage across the device's terminals is positive, it acts as a short circuit. When the voltage across the device's terminals is negative, it acts as an open circuit.   &lt;br /&gt;

==Ideal Operational Amplifier (Op-Amp)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK105.png]]&lt;br /&gt;
&lt;br /&gt;
This is a very basic and primitive model of an operational amplifier. It has only one parameter, open loop gain with a default value of 50,000, which is adequate for most cases. The ideal Op-Amp device doesn't require any DC bias voltages. &lt;br /&gt;

==Ideal Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR1.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal transformer is a four-pin two-port device with the following relationship between the voltages and currents at its primary and secondary ports:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_S} = - \frac{i_S}{i_P} = \frac{N_P}{N_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; are the primary voltage, current and number of turns, respectively, and v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; are the secondary voltage, current and number of turns, respectively. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary turns ratio. Note that the ideal transformer model is defined based on controlled sources and does not involve any magnetic physical parameters as opposed to mutual inductors or ferrite core transformer.&lt;br /&gt;
&lt;br /&gt;
==Inductance Meter==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductance Meter measures the total inductance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total inductance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense an inductance value and alter their behavior based upon it. Care must be exercised when connecting an Inductance Meter to the inductors of a circuit. This is due to the fact that inductors are treated by SPICE as current sources. This can cause a problem when an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. &lt;br /&gt;

==Inductive Coupler Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GK99.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductive Coupler Block couples any two existing inductors. This block doesn't have any pins because it doesn't actually represent inductors, only the coupling between them. This is useful if you want to&lt;br /&gt;
couple two inductors that are in different parts of the circuit, or if you want to couple more than two inductors together. In the latter case, use more than one of these, with each one coupling a pair of inductors.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are Inductor1, Inductor2, and k. Inductor1 is the name of first inductor, Inductor2 is the name of the second inductor, and k is the coefficient of coupling, 0 &amp;amp;lt; k &amp;amp;le; 1.&lt;br /&gt;
&lt;br /&gt;
==Inductive Coupling (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G41.png]]&lt;br /&gt;
&lt;br /&gt;
This function is a conceptual model which is used as a building block to create a wide variety of inductive and magnetic circuit models. This function is normally used in&lt;br /&gt;
conjunction with the “core” model, but it can also be used with resistors, hysteresis blocks, etc. to build up systems which mock the behavior of linear and nonlinear components.&lt;br /&gt;
The lcouple takes as an input (on the “l” port) a current. This current value is multiplied by the num_turns value, N, to produce an output value (a voltage value which appears on the&lt;br /&gt;
mmf_out port). The mmf_out acts similar to a magnetomotive force in a magnetic circuit;&lt;br /&gt;
when the lcouple is connected to the “core” model, or to some other resistive device, a current will flow. This current value (which is modulated by whatever the lcouple is&lt;br /&gt;
connected to) is then used by the lcouple to calculate a voltage “seen” at the “l” port. The voltage is a function of the derivative with respect to time of the current value seen at mmf_out.&lt;br /&gt;
&lt;br /&gt;
The most common use for lcouple will be as a building block in the construction of transformer models. To create a transformer with a single input and a single output, you&lt;br /&gt;
would require two lcouple models plus one “core” model. &lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
A1 (1 0) (2 3) lcouple1&lt;br /&gt;
&lt;br /&gt;
.model lcouple1 lcouple ( num_turns = 10 )&lt;br /&gt;

==Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK121.png]]&lt;br /&gt;
&lt;br /&gt;
Inductors are used to store magnetic energy. An inductor's ability to counteract current changes passing through it is called its inductance (L), which is&lt;br /&gt;
measured in Henrys. In a (steady-state) DC analysis, the inductor acts like a short circuit. It is indeed treated as a current source, which can be problematic if an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. The resistor may be of negligible value or one that accounts for the coil resistance of the inductor. In AC and transient analyses, the inductor develops a voltage across it in response to the changing magnetic&lt;br /&gt;
flux within its coil. &lt;br /&gt;
&lt;br /&gt;
An inductor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
v(t) = L*(di(t)/dt) &lt;br /&gt;
&lt;br /&gt;
The inductor's initial condition is optional. It is the initial value of the inductor current in Amperes that flows from node N+ through the inductor to node N-. The only time that the initial current matters is when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked. &lt;br /&gt;
&lt;br /&gt;
An inductor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
v = j &amp;amp;omega; * L * i&lt;br /&gt;
&lt;br /&gt;
All inductor names must begin with L.&lt;br /&gt;

==Inductor with Ferrite Core==&lt;br /&gt;
&lt;br /&gt;
[[File:GK94.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device models a physical inductor with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. Unlike the standard inductor device, you do not specify an inductance value for the inductor with ferrite core. Rather, you specify physical parameters like cross sectional area, core length and number of turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Insulated Gate Bipolar Transistor (IGBT) device with three pins: Collector(C), Gate (G), and Emitter (E). It is primarily used as a fast electronic switch. The IGBT combines the simple gate-drive characteristics of MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors. The device's model consists of an isolated gate FET for the control input, and a PNP bipolar power transistor as a switch.

This device is an interactive switch that can be closed or opened either directly from the Schematic Editor by clicking on its symbol or from the Instrument Panel.&lt;br /&gt;
&lt;br /&gt;
==Junction Field Effect Transistor (JFET)==&lt;br /&gt;
&lt;br /&gt;
[[File:G12.png]]&lt;br /&gt;
&lt;br /&gt;
The JFET is the simplest transistor device and has three pins: gate, drain and source. The JFET defaults are based on the Shichman and Hodges FET model. This is a square-law device because of the expression relating the drain current to the gate-to-source voltage: &lt;br /&gt;
Idrain=*(VGS-Vthreshold)2.  In real JFETs, near the saturation point, the drain currents vary with the drain voltages. This can be modeled by the following formula:  Idrain=*(VGS-VTO)2*(1+*VDS), which yields an increasing&lt;br /&gt;
drain current for increasing values of VDS.&lt;br /&gt;
&lt;br /&gt;
The gate-to-source and gate-to-drain junctions each have a nonlinear capacitor.  The zero-bias capacitance value is selected for each junction.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

&lt;br /&gt;
The CCCS is a current source whose current is directly proportional to the current across a controlling Ammeter or a voltage source. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the current gain, which has a default value of one. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the current gain.   &lt;br /&gt;

==Lossless Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G21.png]]&lt;br /&gt;
&lt;br /&gt;
The lossless transmission line is a four-pin two-port device that models only one propagating mode of an ideal transmission line.  When using this SPICE model, should all four nodes of the actual circuit be distinct, two modes may be activated, and this device would be insufficient for that purpose. To circumvent this potential problem, two transmission line devices would be required. Due to the implementation details, you may produce more accurate simulation results with a lossy transmission line device with zero loss.&lt;br /&gt;
&lt;br /&gt;
Optional initial condition parameters are the voltage and current at each of the transmission line ports.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are Z0, TD, F, NL, IC, described below:&lt;br /&gt;
&lt;br /&gt;

|NL||normalized electrical length of the transmission line with respect to the wavelength in the line at frequency F. (If F is specified, but NL is not, the default is 0.25.)&lt;br /&gt;

==Lossy Transmission Line==&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The lossy transmission line is a four-pin two-port convolution model for uniform constant-parameter distributed lines. MNAME is the process model name, which&lt;br /&gt;
includes a set of pre-specified options as described below.&lt;br /&gt;
&lt;br /&gt;

The RLC (uniform transmission line with series loss only), RC (uniform RC line), LC (lossless transmission&lt;br /&gt;
line), and RG (distributed series resistance and parallel conductance only) lines have been implemented. &lt;br /&gt;
The length (LEN) must be given.  COMPACTREL and COMPACTABS control the compaction of past history values&lt;br /&gt;
used in convolution.  Larger values for these lower accuracy but improve speed.  These are used with the&lt;br /&gt;
TRYTOCOMPACT option. &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Magnetic Core (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G42.png]]&lt;br /&gt;
&lt;br /&gt;
This device is used as a building block to create a wide variety of inductive and magnetic circuit models. It is almost always to be used in conjunction with the &amp;quot;lcouple&amp;quot; model to build up systems which simulate the behavior of linear and nonlinear magnetic components. There are two fundamental modes of operation for the core model. These are the &amp;quot;PWL&amp;quot; mode (which is the default and most&lt;br /&gt;
likely to be of use to you) and the &amp;quot;Hysteresis&amp;quot; mode.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;PWL Mode (mode = 1)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the PWL mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf) value. This value is divided by the total effective length of the core to produce a value for the Magnetic Field Intensity, H, which is then used to find the corresponding Flux Density, B, using the piecewise linear relationship described by you in the H_array / B_array coordinate pairs. B is then multiplied by the cross-sectional area of the core to find the Flux value, which is output as a current. The pertinent mathematical equations are:&lt;br /&gt;
&lt;br /&gt;
H = mmf / L, where L = Length (in apmere-turns/meter)&lt;br /&gt;
&lt;br /&gt;
B = f(H)&lt;br /&gt;
&lt;br /&gt;
&amp;amp;Phi; = B * A, where A = Area&lt;br /&gt;
&lt;br /&gt;
The B value is derived from a piecewise linear transfer function described to the model by the H_array and B_array coordinate pairs.  This transfer function does not include hysteretic effects; for that, you would need to substitute a HYST model for the core. The magnetic flux value &amp;amp;Phi; in turn is used by the &amp;quot;lcouple&amp;quot;&lt;br /&gt;
code model to obtain a value for the voltage reflected back across its terminals to the driving electrical circuit.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Hysteresis Mode (mode = 2)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the Hysteresis mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf)&lt;br /&gt;
value.  This value is used as input to the equivalent of a hysteresis code model block.  The parameters&lt;br /&gt;
defining the input low and high values, the output low and high values, and the amount of hysteresis are&lt;br /&gt;
as in that model. The output from this mode, as in PWL mode, is a current value which is seen across the magnetic core port.&lt;br /&gt;
&lt;br /&gt;
One final note to be made about the two core models is that certain parameters are specific to one or the other.  In particular, the in_low, in_high, out_lower_limit, out_upper_limit, and hysteresis parameters are not available in PWL mode. Likewise, the H_array, B_array, area, ad length values are unavailable&lt;br /&gt;
in Hysteresis mode.  The input_domain and fraction parameters are common to both modes (though their behavior is somewhat different; for explanation of the input_domain and fraction values for the Hysteresis mode, please refer to the Hysteresis Block discussion.&lt;br /&gt;

&lt;br /&gt;
[[File:G16.png]]&lt;br /&gt;
&lt;br /&gt;
The marker serves several purposes:&lt;br /&gt;
&lt;br /&gt;
* It can appear as a default plot in simulations if the &amp;amp;quot;Voltage Probe&amp;amp;quot; box is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to set the initial voltage or voltage guess at the node it is connected to.&lt;br /&gt;
&lt;br /&gt;
* It can be used as a port for a subcircuit when you choose the checkbox labeled &amp;quot;Use as Subcircuit Port&amp;quot; is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to explicitly set a node number in place of the arbitrarily assigned node number by the program. In this case, make sure the &amp;amp;quot;Set Node Index&amp;amp;quot; box is checked.  Otherwise, it will act as just a voltage probe.&lt;br /&gt;
&lt;br /&gt;
* It can be used to connect different parts of a circuit in place of wires. To use markers as virtual connectors, place them at points where wires would otherwise connect. Then set the Part Title of the two (or more) markers to the same name, and they will act as a single circuit node.&lt;br /&gt;

==MESFET==&lt;br /&gt;
&lt;br /&gt;
[[File:G14.png]]&lt;br /&gt;
&lt;br /&gt;
The MESFET is a Schottky-barrier gate FET with six times greater electron mobility than silicon.  MESFETs are important devices for creating high frequency circuits. They function by creating a potential barrier between the gate and the channel when the metal gate&lt;br /&gt;
contacts the gallium-arsenide substrate. Electron velocity saturates for fields approximately ten times lower than with silicon.  The Curtice model includes linear and saturated operation.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

The MOSFET is an active device that has up to 4 pins.  The three standard pins are gate, drain, and source.  These are given in the default symbol.  The bulk node, which is grounded by default, is the fourth pin.  The MOSFET with the bulk is named mos_n_lvl1_4 (the lvl1 is for level 1, the n for nmos, and the 4 for 4 pins.)&lt;br /&gt;

There are five different default models: square-law I-V characteristic, analytical, semi-empirical, and BSIM and BSIM2 (Berkeley Short-channel IGFET Model), which include second-order effects such as channel-length&lt;br /&gt;
modulation, subthreshold conduction, scattering-limited velocity saturation, small-size effects, and charge-controlled capacitance.  The process parameter LEVEL specifies which of the models is chosen as indicated below:&lt;br /&gt;

&lt;br /&gt;
The mutual inductors device is a pair of inductors that are coupled to each other.  L1 and L2 are the names of two inductors. You have to specify the inductance of inductor L1, the inductance of inductor L2, the initial current through each, and the coupling coefficient k, 0 &amp;amp;le; k &amp;amp;le; 1. The mutual inductance M expressed in units of H can be calculated using the following definition:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; k = \frac{M}{\sqrt{L_1 L_2}} &amp;lt;/math&amp;gt;&lt;br /&gt;

==Non-Ideal Current Transformer==&lt;br /&gt;

[[File:GK104.png]]&lt;br /&gt;
&lt;br /&gt;
This 8-pin device models a non-ideal lossy current transformer. Its model consists of an ideal transformer with more secondary turns than primary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. on each side of the internal ideal transformer, there is a series leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, followed by a shunt winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a series winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, which connects to the exterior positive pin on that side. The inter-winding resistance R&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the negative pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance. &lt;br /&gt;

&lt;br /&gt;
This 2-pin device is a basic simplified model of a diode as a rectifier or switch. When forward-biased, it acts as a low-valued voltage source. When reverse-biased, it acts as an open circuit until the reverse voltage exceeds the specified breakdown voltage. Then it acts as a high-valued voltage source of the reverse polarity. &lt;br /&gt;

&lt;br /&gt;
This 8-pin device models a non-ideal lossy voltage transformer. Its model consists of an ideal transformer with more primary turns than secondary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. There are series combinations of a winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; on the primary and secondary sides. These are connected between the positive interior and exterior pins on each side. There are also two shunt branches at the inputs of the primary and secondary sides (connected between the positive and negative exterior pins), each consisting of a distributed turn-to-turn winding resistance RDC&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; in series with a distributed turn-to-turn winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;. The inter-winding capacitance CWW&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the positive pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance.  &lt;br /&gt;

==Nonlinear Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK89.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear capacitor model allows the capacitor to be described by an arbitrary relationship between the capacitor's charge Q and the voltage V across the capacitor. In other words, Q = f(V). The nonlinear capacitance is then defined as C(V) = dQ/dV. You need to define the charge Q by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ C_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear capacitor, where Q = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, C = C(V) = dQ/dV = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Conductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK88.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear conductor model allows the conductor to be described by an arbitrary relationship between the conductor's current I and the voltage V across the conductor. In other words, I = f(V). The nonlinear conductance is then defined as G(V) = dI/dV. You need to define the current I by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ G_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear conductor, where I = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, G = G(V) = dI/dV = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Dependent Sources==&lt;br /&gt;
&lt;br /&gt;
[[File:G18.png]]&lt;br /&gt;
&lt;br /&gt;
Nonlinear dependent (arbitrary) sources use an equation or mathematical expression to describe their behavior. One and only one of the two forms: V=&amp;amp;lt;expr&amp;amp;gt; or  I=&amp;amp;lt;expr&amp;amp;gt; must be given.&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; v = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; i = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Examples: &lt;br /&gt;
&lt;br /&gt;
v = I(v1) + 3* I(v2)&lt;br /&gt;
&lt;br /&gt;
I = v(i1) + 3* v(2) + 5 * v(3) ^2&lt;br /&gt;
&lt;br /&gt;
The first example is a current-controlled voltage source.  The v on the left side of the equation&lt;br /&gt;
indicates that it is a voltage source.  I(v1) and I(v2) are the currents through voltage sources named v1 and v2, respectively.&lt;br /&gt;
&lt;br /&gt;
The second example is a voltage-controlled current source.  v(2) and v(3) represents the voltages at nodes 2 and 3, respectively, and v(i1) represents the voltage across a current source named i1.&lt;br /&gt;
&lt;br /&gt;
The following mathematical functions defined for real variables can be used in the expressions:&lt;br /&gt;
&lt;br /&gt;
abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), atanh(x), cos(x), cosh(x), exp(x), ln(x), log(x), max(x,y), min(x,y), pwr(x,y), pwrs(x,y), sgn(x), sin(x), sinh(x), sqrt(x), tan(x), tanh(x), u(x), uramp(x).&lt;br /&gt;
&lt;br /&gt;
The function &amp;amp;quot;sgn&amp;amp;quot; is the signum function and its value is 1 if the argument is positive or zero and -1 if the argument is negative. &lt;br /&gt;
The function &amp;amp;quot;u(x)&amp;amp;quot; is the unit step and &amp;amp;quot;uramp(x)&amp;amp;quot; is the integral of the unit step.  The&lt;br /&gt;
unit step is one if its argument is greater than zero and zero if its argument is less than zero.  The&lt;br /&gt;
ramp function (uramp) is 0 for argument values less than zero and equal to the argument for argument values&lt;br /&gt;
greater than zero.&lt;br /&gt;
&lt;br /&gt;
The following operators are permissible:  +, -, *, /, and ^.&lt;br /&gt;
&lt;br /&gt;
The power functions have equivalent expressions: pwr(x,y) = x^y and pwrs(x,y) = sgn(x)*abs(x)^y.&lt;br /&gt;
&lt;br /&gt;
Two constants can also be used in expressions: pi = 3.1415926 and e = 2.7182818.&lt;br /&gt;
&lt;br /&gt;
There is a conditional function with the syntax IF(Condition, Expression1, Expression2). If &amp;quot;Condition&amp;quot; is met, then the return value of the function is Expression1; otherwise, it is Expression2. An example of this type of function is IF(v(1)&amp;gt;=0,1,-1), which is equivalent to sgn(v(1)). &lt;br /&gt;
&lt;br /&gt;
To get time into an expression, integrate the current from a constant current source with a capacitor&lt;br /&gt;
and use the voltage across the capacitor.&lt;br /&gt;
&lt;br /&gt;

==Nonlinear Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK90.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear inductor model allows the inductor to be described by an arbitrary relationship between the inductor's magnetic flux &amp;amp;Phi; and the current I flowing through the inductor . In other words, &amp;amp;Phi;  = f(I). The nonlinear inductance is then defined as L(I) = d&amp;amp;Phi;/dI. You need to define the flux &amp;amp;Phi; by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ L_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear inductor, where &amp;amp;Phi; = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, L = L(I) = d&amp;amp;Phi;/dI = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.  &lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(i(vx))^2.&lt;br /&gt;

==Nonlinear Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK87.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear resistor model allows the resistor to be described by an arbitrary relationship between the voltage V across the resistor and its current I. In other words, V = f(I). The nonlinear resistance is then defined as R(I) = dV/dI. You need to define the voltage V by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ R_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear resistor, where V = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, R = R(I) = dV/dI = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 10*(i(vx))^2.&lt;br /&gt;

[[File:GK105.png]]&lt;br /&gt;
&lt;br /&gt;
This three-pin device models a parameterized operational amplifier with a very high voltage gain, a very high input impedance and a very low output impedance. The behavioral model of the parameterized Op-Amp device is based on the algorithm found in the book &amp;lt;B&amp;gt;Macromodeling with Spice&amp;lt;/B&amp;gt;,&lt;br /&gt;
authored by Connelly &amp;amp;amp; Choi, published by Prentice Hall. The default parameters are those of the 741 Op-Amp. This device doesn't require external DC bias voltage sources. Its positive and negative DC bias voltages are specified as its parameters. Sometimes the simulation doesn't converge if there is no DC path from the output of the Op-Amp to the ground.&lt;br /&gt;

== Optocoupler ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK115.png]]&lt;br /&gt;
&lt;br /&gt;
This is a five-pin parameterized optocoupler device. Its model consists of an ideal diode device in series with an Ohmic resistance connected between the Anode (A) and Cathode (K) pins together with a bipolar junction transistor device with three accessible pins, Collector (C), Base (B) and Emitter (E). A current-controlled current source is connected between base and collector of the BJT, whose current is controlled by the current passing through the diode. The proportionality constant is twice the specified value of the current transfer ratio (ctr) parameter. &lt;br /&gt;
&lt;br /&gt;
You can change or enhance the models of the diode and BJT by adding more parameters. To do so, you have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

[[File:GK113.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 4-pin parameterized photodiode device. A pair of pins, Anode (A) and Cathode (K), represent the physical terminals of the photodiode. The photodiode model connected between the anode and cathode pins consists of the parallel connection of an ideal diode, a dark current source, a noise current source, a current-controlled current source, a diode capacitance, a shunt resistance altogether with a series resistance.  &lt;br /&gt;
&lt;br /&gt;
Another pair of pins IS+ and IS- act as an ammeter that must be inserted in a control circuit. The current passing through this ammeter controls the current of the photodiode. The default proportionality constant is unity. The controlling current is typically a function of light intensity incident on the surface of the photodiode.    &lt;br /&gt;

==Piecewise Linear (PWL) Controlled Source==&lt;br /&gt;
&lt;br /&gt;
[[File:GL49.png]]&lt;br /&gt;
&lt;br /&gt;
The Piecewise Linear (PWL) Controlled Source is a single-input and single-output function generator whose output is not necessarily&lt;br /&gt;
linear for all input values. Instead, it follows an I/O relationship that is specified by the x_array and y_array coordinates. The x_array and y_array values represent vectors of coordinate points on the x and y axes, respectively. The x_array values are progressively increasing input coordinate points, and the associated y_array values represent the outputs at those points.  There may be as few as two pairs specified, or as many as memory and simulation speed allow.&lt;br /&gt;
&lt;br /&gt;
In order to fully specify outputs for values of Vin outside of the bounds of the PWL function, the PWL&lt;br /&gt;
controlled source model extends the slope found between the lowest two coordinate pairs and the highest&lt;br /&gt;
two coordinate pairs.  This has the effect of making the transfer function completely linear for Vin&lt;br /&gt;
less than x_array[0] and Vin greater than x_array[n]. It also has the potentially subtle effect of unrealistically&lt;br /&gt;
causing an output to reach a very large or small value for large inputs. You should thus keep in mind&lt;br /&gt;
that the PWL Source does not inherently provide a limiting capability.&lt;br /&gt;
&lt;br /&gt;
In order to diminish the potential for divergence of simulations when using the PWL block, a form&lt;br /&gt;
of smoothing around the x_array and y_array coordinate points is necessary.  This is due to the iterative&lt;br /&gt;
nature of the simulator and its reliance on smooth first derivatives of  transfer functions in order to&lt;br /&gt;
arrive at a matrix solution.  Consequently, the two parameters &amp;quot;input_domain&amp;quot; and &amp;quot;fraction&amp;quot; are included&lt;br /&gt;
to allow you some control over the amount and nature o the smoothing performed.&lt;br /&gt;
&lt;br /&gt;
Fraction is a switch that is either TRUE or FALSE.  When TRUE (the default setting), the simulator assumes&lt;br /&gt;
that the specified input_domain value is to be interpreted as a fractional figure.  Otherwise, it is interpreted&lt;br /&gt;
as an absolute value.  Thus, if fraction = TRUE and input_domain = 0.10, the simulator assumes that the smoothing&lt;br /&gt;
radius about each coordinate point is to be set equal to 10% of the length of either the x_array segment&lt;br /&gt;
above each coordinate point, or the x_array segment below each coordinate point. The specific segment&lt;br /&gt;
length chosen will be the smallest of these two for each coordinate point.&lt;br /&gt;
&lt;br /&gt;
If fraction = FALSE and input_domain = 0.10, then the simulator will begin smoothing the transfer function at 0.10&lt;br /&gt;
volts (or amperes) below each x_array coordinate and will continue the smoothing process for another 0.10&lt;br /&gt;
volts (or amperes) above each x_array coordinate point.&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Programmable Unijunction Transistor (PUT) device with three pins: Base 1 (B1), Base 2 (B2) and Emitter (E). It is biased with a positive voltage between the two bases. This device has a unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. It exhibits a negative resistance characteristic and so it can be employed as an oscillator. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively. To change these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.    &lt;br /&gt;

==Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK119.png]]&lt;br /&gt;
&lt;br /&gt;
Resistors are passive devices that dissipate power. Their resistance value varies depending on how much power they can dissipate and is measured&lt;br /&gt;
in Ohms.  The transient, DC and AC behaviors of a resistor are all described by the same equation:&lt;br /&gt;
&lt;br /&gt;
v = R * i&lt;br /&gt;
&lt;br /&gt;
where v is the voltage across the resistor, i is the current passing through the resistor, and R is the resistance. The value of R must be nonzero. &lt;br /&gt;
&lt;br /&gt;
All resistor names must begin with R.&lt;br /&gt;

&lt;br /&gt;
[[RF.Spice A/D]] provides three types of resistor: Simple, User-Defined (Real Resistor) and Semiconductor. The resistance of the simple resistor is a single value expressed in Ohms. You can also set the Monte Carlo tolerance for this resistor.&lt;br /&gt;
&lt;br /&gt;
==Schottky Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK80.png]]&lt;br /&gt;
&lt;br /&gt;
The Schottky diode has the same model as the generic diode with a nonzero transit time (tt), a nonzero junction capacitance (cjo) and a typically larger saturation current (is), a lower junction potential (vj) and a smaller grading coefficient (m).   &lt;br /&gt;
&lt;br /&gt;
==Semiconducting Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK83.png]]&lt;br /&gt;
&lt;br /&gt;
This is the more general form of the Capacitor model and allows for the calculation of the actual capacitance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
CXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;IC=VAL&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it defines the capacitance. If MNAME is specified, then the capacitance is calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. Either VALUE or MNAME, LENGTH, and WIDTH may be specified, but not both sets. The optional initial condition &amp;quot;IC&amp;quot; is the initial voltage across the capacitor for transient simulations.&lt;br /&gt;
&lt;br /&gt;
The capacitance is computed as:&lt;br /&gt;
&lt;br /&gt;
CAP = CJ * (LENGTH - NARROW) * (WIDTH - NARROW)+ 2 * CJSW * (LENGTH + WIDTH - 2NARROW) * CAP&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the capacitor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit CJ, CJSW, NARROW, DEFW, and CAP.&lt;br /&gt;

&lt;br /&gt;
This is the more general form of the resistor model and allows for the modeling of temperature effects and for the calculation of the actual resistance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
If VALUE is specified, it overrides the geometric information and defines the resistance. If MNAME is specified, then the resistance may be calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. The (optional) TEMP value is the temperature at which this device is to operate, and overrides the temperature specification in the SPICE Options Dialog. &lt;br /&gt;
&lt;br /&gt;
The resistance is computed as:&lt;br /&gt;
&lt;br /&gt;
R(T0) = (RSH) * [(L - NARROW) / (W - NARROW)] * RES&lt;br /&gt;
&lt;br /&gt;
R(T) = R(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;

== Triac Thyristor ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK110.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin bidirectional thyristor device that conducts current in either direction when triggered. A thyristor is analogous to a relay in that a small voltage and current can control a much larger voltage and current. The triac has two anode pins termed Main Terminal 1 (MT1) and Main Terminal 2 (MT2) and a Gate (G) pin. In order to create a triggering current for a triac, either a positive or negative voltage can be applied to the gate. Once triggered, the thyristor continues to conduct, even if the gate current ceases, until the main current drops below a certain level called the holding current. The device's model involves two NPN BJT transistors and two PNP BJT transistors. The forward beta parameters of the NPN and PNP transistors are set equal to 20 and 5, respectively. To changes these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.&lt;br /&gt;

==Uniform RC Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G23.png]]&lt;br /&gt;
&lt;br /&gt;
The standard parameters are L, and N.  They are described below:&lt;br /&gt;
&lt;br /&gt;
Two of the nodes are the element nodes connected by the RC line.  The third is the node to which the capacitances&lt;br /&gt;
are connected.  L is the length of the RC line in meters.  N is the number of lumped segments to use in&lt;br /&gt;
modeling the RC line.&lt;br /&gt;
&lt;br /&gt;
This device is derived from a model proposed by Gertzberrg.  It expands the URC line into a network of&lt;br /&gt;
lumped RC segments with internally generated nodes.  These segments increase toward the middle of the&lt;br /&gt;
URC line in a geometric progression with K as the proportionality constant.&lt;br /&gt;
&lt;br /&gt;
The URC line is made up entirely of resistor and capacitor segments, unless the ISPERL parameter has a&lt;br /&gt;
non-zero value.  In this case, capacitors are replaced by reverse biased diodes with an equivalent zero-bias&lt;br /&gt;
junction capacitance, a saturation current of ISPERL amps per meter of transmission line, and optional&lt;br /&gt;
series resistance of RSPERL ohms per meter. &lt;br /&gt;

==Voltage-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G19.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Voltage-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Voltmeter or controlling voltage nodes, as well as the turn-on and turn-off voltages in Volts and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the rest of [[parameters]]. When the voltage across the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the voltage across the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Voltage Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17A.png]]&lt;br /&gt;
&lt;br /&gt;
A voltage source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a voltage source is its initial transient value. For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset voltage. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==XSpice Devices and their models==&lt;br /&gt;
&lt;br /&gt;
XSpice devices have the following form:&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 4pt  0pt  1px  0pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;

e.g., A2 1  2  transfer_function&lt;br /&gt;
&lt;br /&gt;
Note that XSpice devices must start with the &amp;amp;quot;A&amp;amp;quot; designation, much as a resistor starts with&lt;br /&gt;
an &amp;amp;quot;R&amp;amp;quot;.  Some devices will have grouped (or vector) pins and are designated by being placed&lt;br /&gt;
inside square brackets.  In the example shown below, the 1 and 2 pins are grouped.  Pin 3 is not.  &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  0pt ; text-indent: 36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
A1 [1   2]  3 summer &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Some models will have voltage differential pairs of pins and will be denoted by a %vd( ).  In the following&lt;br /&gt;
example pins 1 and 4 are differential pairs, as well as pins 2 and 3.  Differential pairs must go between&lt;br /&gt;
parentheses (). &lt;br /&gt;
&lt;br /&gt;

A1 %vd(1   4)   %vd(2   3)  triangle &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Refer to individual devices for more information.&lt;br /&gt;
&lt;br /&gt;
Each XSpice device will also have a model associated with it.  Each model will have the following form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
.model &amp;amp;lt;model_name&amp;amp;gt; &amp;amp;lt;model_identifier&amp;amp;gt; {&amp;amp;lt;pname1 = pval1&amp;amp;gt;} {&amp;amp;lt;pname2 = pval2&amp;amp;gt;} &lt;br /&gt;
...&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
e.g., .model transfer_function s_xfer  in_offset = 0.0  gain = 1.0&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Model_name refers to the name given in the device line.  Model_identifier is an internal designation and&lt;br /&gt;
must be of an existing designation  Refer to each device's example for the correct designation. &lt;br /&gt;
&lt;br /&gt;
Parameter values are optional.  If they aren't specified, then the default will be used.  Some devices&lt;br /&gt;
have parameters that require a value and must be specified.  Refer to individual devices for any required parameters.&lt;br /&gt;
&lt;br /&gt;
==Zener Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:G10.png]]&lt;br /&gt;
&lt;br /&gt;
The Zener Diode models the DC characteristics of most zeners. Since most data sheets for zener diodes do&lt;br /&gt;
not give detailed characteristics in the forward region, only a single point defines the forward characteristicThe&lt;br /&gt;
saturation current refers to the relatively constant reverse current that is produced when the voltage&lt;br /&gt;
across the zener is negative, but breakdown has not been reached.  The reverse leakage current determines&lt;br /&gt;
the slight increase in reverse current as the voltage across the zener becomes more negative.  It is modeled&lt;br /&gt;
as a resistance parallel to the zener with value v_breakdown / i_rev.&lt;br /&gt;
&lt;br /&gt;
Note that the limt_switch parameter engages an internal limiting function for the zener.  This can, in&lt;br /&gt;
some cases, prevent the simulator from converging to an unrealistic solution if the voltage across or&lt;br /&gt;
current into the device is excessive.  If use of this feature fails to yield acceptable results, the convlimit&lt;br /&gt;
option should be tried (add the following statement to the SPICE input deck:  .options convlimit)&lt;br /&gt;

==Analog-to-Digital Converter (ADC) Bridge==&lt;br /&gt;
[[File:GK42.png]]&lt;br /&gt;
&lt;br /&gt;
The ADC Bridge takes an analog value from an analog node and may be in the form of a voltage or current.&lt;br /&gt;
If the input is less than or equal to &amp;amp;quot;in_low&amp;amp;quot;, then a digital &amp;amp;quot;0&amp;amp;quot; is generated. If&lt;br /&gt;
the input is greater than or equal to &amp;amp;quot;in_high&amp;amp;quot;, a digital &amp;amp;quot;1&amp;amp;quot; is generated. Otherwise,&lt;br /&gt;
a digital &amp;amp;quot;UNKNOWN&amp;amp;quot; is the output value. Unlike the DAC Bridge, ramping or delay is not applicable.&lt;br /&gt;
Rather, the continuous ramping of the input provides for any associated delays in the digitized signal.&lt;br /&gt;
&lt;br /&gt;
This model also posts an input load value based on the parameter input_load.&lt;br /&gt;

&lt;br /&gt;
Examples:&lt;br /&gt;
&lt;br /&gt;

==Bipolar Junction Transistor (BJT)==&lt;br /&gt;
[[File:G11.png]]&lt;br /&gt;
&lt;br /&gt;
The BJT is an active device which has up to 4 pins.  The three standard pins are base, emitter, and collector.  These are given in the default symbol.  The substrate, which is grounded by default, is the fourth pin.  To use the BJT with the substrate, create a new 4-pin BJT using the Device Editor and Symbol Editor.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;
&lt;br /&gt;
{| class=&amp;quot;wikitable&amp;quot;&lt;br /&gt;
|-&lt;br /&gt;
|AREA||area factor (optional) (If not specified, the default value is 1.0.)&lt;br /&gt;
|-&lt;br /&gt;
|OFF||initial condition for the DC analysis (optional)&lt;br /&gt;
|-&lt;br /&gt;
|IC||initial condition (optional) (Used when a transient analysis is desired, which starts from other than the quiescent operating point.)&lt;br /&gt;
|-&lt;br /&gt;
|T||operating temperature of the device (optional)&lt;br /&gt;
|-&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
Area factor scales the model parameters RE and RC.  IC VBE is the initial voltage from base emitter. IC VCE is the initial voltage from collector to emitter.  TEMP is the overriding temperature. These parameters are based on the Gummel and Poon integral-charge model.  If these parameters are not specified, then it will reduce to the simpler Ebers-Moll model. &lt;br /&gt;
&lt;br /&gt;
The process model is mandatory for the BJT.  Descriptions of the process model parameters are given in the following table:&lt;br /&gt;

==Capacitance Meter==&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Capacitance Meter measures the total capacitance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total capacitance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense a capacitance value and alter their behavior based upon it.&lt;br /&gt;

==Capacitor==&lt;br /&gt;
[[File:GK120.png]]&lt;br /&gt;
&lt;br /&gt;
Capacitors are used to store electrical energy.  They can filter or remove AC signals or block DC current without disrupting AC signals. A capacitor's ability to store energy is termed capacitance and is measured in Farads, with values from pF to mF. The only time current flows through a capacitor is when the charge is collected on, or is removed from, its parallel plates. This means that the voltage across the capacitor is changing, which doesn't conform to DC analysis. In a physical circuit, there is a transition stage during which capacitors charge up to their final values. The result is the same as if these capacitors did not exist and the connections to them were left dangling. In other words, in a (steady-state) DC analysis, a capacitor behaves like an open circuit. Therefore, it is important that no section of the circuit is isolated from the capacitors. Every circuit node needs some path for DC current to the ground.&lt;br /&gt;
&lt;br /&gt;
A capacitor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
i(t) = C * (dv(t)/dt)&lt;br /&gt;
&lt;br /&gt;
Its initial voltage is only important when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked.&lt;br /&gt;
&lt;br /&gt;
An capacitor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
i = j ω * C * v &lt;br /&gt;
&lt;br /&gt;
All capacitor names must begin with C. &lt;br /&gt;

[[RF.Spice A/D]] provides three types of capacitors: simple, user-defined (or real) and semiconductor. The standard capacitor parameters are N+, N-, VALUE, and IC. In a simple capacitor, VALUE must&lt;br /&gt;
be specified for the capacitance in Farads. IC is the (optional) initial condition for the capacitor voltage.&lt;br /&gt;

==Center-Tapped Ferrite Core Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:GK97.png]]&lt;br /&gt;
&lt;br /&gt;
This five-pin three-port device models a center-tapped physical transformer with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. For this device you need to specify physical parameters like cross sectional area, core length and number of primary and secondary turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;
B_array = [-0.375 -0.36 -0.32 -0.29 -0.24 -0.15 0 0.15 0.24 0.29 0.32 0.36 0.375]&lt;br /&gt;
&lt;br /&gt;
To change the value of H/B arrays, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

==Current Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17B.png]]&lt;br /&gt;
&lt;br /&gt;
Current source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a current source is its initial transient value.  For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset current. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==Current-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G20.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Current-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the turn-on and turn-off currents in Amperes and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the rest of [[parameters]]. When the current through the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the current through the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Darlington Pair==&lt;br /&gt;
&lt;br /&gt;
[[File:GK108.png]]&lt;br /&gt;
&lt;br /&gt;
A Darlington pair is a three-pin device that consists of two interconnected BJT transistors of the same type. The collectors of two transistors are connected together to provide the &amp;quot;Collector&amp;quot; pin of the pair. The base of the first BJT acts the &amp;quot;Base&amp;quot; pin of the pair. The emitter of the first BJT is internally connected to the base of the second BJT. The emitter of the second BJT acts as the &amp;quot;Emitter&amp;quot; pin of the pair. There are two types of Darlington pair: NPN and PNP. The parameterized generic Darlington pair also contains a diode connected between the collector and emitter pin as well as two base-emitter resistors, one across each BJT.     &lt;br /&gt;

==Frequency Meter==&lt;br /&gt;
[[File:G114.png]]&lt;br /&gt;
&lt;br /&gt;
The Frequency Meter is a four-pin shunt device that is connected in parallel with an AC source just like a voltmeter and measures the operating frequency of the AC circuit. The input pins are connected across the AC source. The voltage across the output pins is equal to the frequency of the source in Hertz within a scale factor SF. Note that the Frequency Meter is designed to work with a single-tone AC source of unit amplitude. If the amplitude of the source is not one, multiply the SF parameter by the non-unit source amplitude value. The output voltage of the Frequency Meter can be used in conjunction with linear or nonlinear dependent sources to model frequency-dependent quantities.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Model Identifier: fmeter&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Parameters:&lt;br /&gt;
&lt;br /&gt;
The only parameter is the scale factor SF with a default value of 1.0. Set SF = 1e-6 to read out the frequency in MHz. Set SF = 1e-9 to read out the frequency in GHz. Set SF = 6.283185 (2*pi) to read out the angular frequency &amp;amp;omega; in radian/s.  &lt;br /&gt;
&lt;br /&gt;
== Fuse ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK76.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 2-pin interactive current-controlled switch. If the current passing through the fuse is less than a specified threshold current, the switch is closed. If the current exceeds the threshold level, the fuse breaks and remains open thereafter. The device's symbol changes to display its state.   &lt;br /&gt;

==Ground==&lt;br /&gt;
&lt;br /&gt;
[[File:G15.png]]&lt;br /&gt;
&lt;br /&gt;
Ground has a voltage of zero (0) and is used as a reference to compute electrical values in the circuit. &lt;br /&gt;
All circuits &amp;lt;B&amp;gt;must&amp;lt;/B&amp;gt; be grounded to be properly simulated.  There is no limit on the number of grounds&lt;br /&gt;
you may use in a circuit.  All components connected to ground are referenced to a common point and treated&lt;br /&gt;
as linked through ground.&lt;br /&gt;
&lt;br /&gt;
==Hysteresis Block (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Hysteresis block is a simple buffer stage that provides hysteresis of the output with respect to the&lt;br /&gt;
input.  The in_low and in_high parameter values.  The output values are limited to out_lower_limit and&lt;br /&gt;
out_upper_limit.  The value of \93hyst\94 is added to the in_low and in_high points in order to specify the&lt;br /&gt;
points at which the slope of the hysteresis function would normally change abruptly as the input transitions&lt;br /&gt;
from a low to a high value.  Likewise, the value of \93hyst\94 is subtracted from the in_high and in_low values&lt;br /&gt;
in order to specify the points at which the slope of the hysteresis function would normally change abruptly&lt;br /&gt;
as the input transitions from a high to a low value.  In fact, the slope of the hysteresis function is&lt;br /&gt;
never allowed to change abruptly but is smoothly varied whenever the input_dowmain smoothing parameter&lt;br /&gt;
is set greater than zero.&lt;br /&gt;

==Ideal Center-Tapped Transformer with Push-Pull Input==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR4.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal center-tapped transformer with push-pull input is a five-pin three-port device with two primary input ports and one secondary output port. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P1}{v_S} = \frac{v_P2}{v_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; is the secondary voltage, v&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt; is measured between the top primary pin P1 and the center tap pin, and v&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom primary pin P2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P1&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P2&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.        &lt;br /&gt;
&lt;br /&gt;
==Ideal Center-Tapped Transformer with Push-Pull Output==&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The ideal center-tapped transformer with push-pull output is a five-pin three-port device with one primary input port and two secondary output ports. Its model is based on the [[Glossary_of_Generic_Analog_Devices#Ideal_Transformer | Ideal Transformer]], and the relationship between its primary and secondary voltages is given by:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_{S1}} = \frac{v_P}{v_{S2}} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; is the primary voltage, v&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; is measured between the top secondary pin S1 and the center tap pin, and v&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt; is measured between the center tap pin and the bottom secondary pin S2. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S1&amp;lt;/sub&amp;gt; = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S2&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary (half-winding) turns ratio.&lt;br /&gt;
&lt;br /&gt;
==Ideal Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK106.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device is a very basic and primitive model of a diode as a rectifier or switch. When the voltage across the device's terminals is positive, it acts as a short circuit. When the voltage across the device's terminals is negative, it acts as an open circuit.   &lt;br /&gt;
&lt;br /&gt;

==Ideal Operational Amplifier (Op-Amp)==&lt;br /&gt;
&lt;br /&gt;
[[File:GK105.png]]&lt;br /&gt;
&lt;br /&gt;
This is a very basic and primitive model of an operational amplifier. It has only one parameter, open loop gain with a default value of 50,000, which is adequate for most cases. The ideal Op-Amp device doesn't require any DC bias voltages. &lt;br /&gt;

==Ideal Transformer==&lt;br /&gt;
&lt;br /&gt;
[[File:XFMR1.png]]&lt;br /&gt;
&lt;br /&gt;
The ideal transformer is a four-pin two-port device with the following relationship between the voltages and currents at its primary and secondary ports:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; \frac{v_P}{v_S} = - \frac{i_S}{i_P} = \frac{N_P}{N_S} = n &amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where v&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt; are the primary voltage, current and number of turns, respectively, and v&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, i&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt; are the secondary voltage, current and number of turns, respectively. The red dots show the polarity of the windings on each side. This model has one parameter: ratio = n = N&amp;lt;sub&amp;gt;P&amp;lt;/sub&amp;gt;/N&amp;lt;sub&amp;gt;S&amp;lt;/sub&amp;gt;, which represents the primary-to-secondary turns ratio. Note that the ideal transformer model is defined based on controlled sources and does not involve any magnetic physical parameters as opposed to mutual inductors or ferrite core transformer.&lt;br /&gt;
&lt;br /&gt;
==Inductance Meter==&lt;br /&gt;
&lt;br /&gt;
[[File:G37.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductance Meter measures the total inductance between a circuit node and the ground. The input pin of the device is connected to the measurement node. The output voltage of the device is then a scaled value equal to the total inductance seen on its input multiplied by the gain parameter. This model is primarily intended as a building block for other models which must sense an inductance value and alter their behavior based upon it. Care must be exercised when connecting an Inductance Meter to the inductors of a circuit. This is due to the fact that inductors are treated by SPICE as current sources. This can cause a problem when an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. &lt;br /&gt;

==Inductive Coupler Block==&lt;br /&gt;
&lt;br /&gt;
[[File:GK99.png]]&lt;br /&gt;
&lt;br /&gt;
The Inductive Coupler Block couples any two existing inductors. This block doesn't have any pins because it doesn't actually represent inductors, only the coupling between them. This is useful if you want to&lt;br /&gt;
couple two inductors that are in different parts of the circuit, or if you want to couple more than two inductors together. In the latter case, use more than one of these, with each one coupling a pair of inductors.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are Inductor1, Inductor2, and k. Inductor1 is the name of first inductor, Inductor2 is the name of the second inductor, and k is the coefficient of coupling, 0 &amp;amp;lt; k &amp;amp;le; 1.&lt;br /&gt;
&lt;br /&gt;
==Inductive Coupling (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G41.png]]&lt;br /&gt;
&lt;br /&gt;
This function is a conceptual model which is used as a building block to create a wide variety of inductive and magnetic circuit models. This function is normally used in&lt;br /&gt;
conjunction with the “core” model, but it can also be used with resistors, hysteresis blocks, etc. to build up systems which mock the behavior of linear and nonlinear components.&lt;br /&gt;
The lcouple takes as an input (on the “l” port) a current. This current value is multiplied by the num_turns value, N, to produce an output value (a voltage value which appears on the&lt;br /&gt;
mmf_out port). The mmf_out acts similar to a magnetomotive force in a magnetic circuit;&lt;br /&gt;
when the lcouple is connected to the “core” model, or to some other resistive device, a current will flow. This current value (which is modulated by whatever the lcouple is&lt;br /&gt;
connected to) is then used by the lcouple to calculate a voltage “seen” at the “l” port. The voltage is a function of the derivative with respect to time of the current value seen at mmf_out.&lt;br /&gt;
&lt;br /&gt;
The most common use for lcouple will be as a building block in the construction of transformer models. To create a transformer with a single input and a single output, you&lt;br /&gt;
would require two lcouple models plus one “core” model. &lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
A1 (1 0) (2 3) lcouple1&lt;br /&gt;
&lt;br /&gt;
.model lcouple1 lcouple ( num_turns = 10 )&lt;br /&gt;

==Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK121.png]]&lt;br /&gt;
&lt;br /&gt;
Inductors are used to store magnetic energy. An inductor's ability to counteract current changes passing through it is called its inductance (L), which is&lt;br /&gt;
measured in Henrys. In a (steady-state) DC analysis, the inductor acts like a short circuit. It is indeed treated as a current source, which can be problematic if an inductor is connected in series with a current source, or in series with a voltmeter, or in series with another inductor. The resistor may be of negligible value or one that accounts for the coil resistance of the inductor. In AC and transient analyses, the inductor develops a voltage across it in response to the changing magnetic&lt;br /&gt;
flux within its coil. &lt;br /&gt;
&lt;br /&gt;
An inductor's transient behavior is described by the equation:&lt;br /&gt;
&lt;br /&gt;
v(t) = L*(di(t)/dt) &lt;br /&gt;
&lt;br /&gt;
The inductor's initial condition is optional. It is the initial value of the inductor current in Amperes that flows from node N+ through the inductor to node N-. The only time that the initial current matters is when the simulator performs a transient analysis, and the &amp;quot;Use Initial Conditions&amp;quot; checkbox is checked. &lt;br /&gt;
&lt;br /&gt;
An inductor's AC behavior is described by the equation: &lt;br /&gt;
&lt;br /&gt;
v = j &amp;amp;omega; * L * i&lt;br /&gt;
&lt;br /&gt;
All inductor names must begin with L.&lt;br /&gt;

==Inductor with Ferrite Core==&lt;br /&gt;
&lt;br /&gt;
[[File:GK94.png]]&lt;br /&gt;
&lt;br /&gt;
This 2-pin device models a physical inductor with a magnetic ferrite core. Its model is based on XSPICE's magnetic core and inductive coupling models. Unlike the standard inductor device, you do not specify an inductance value for the inductor with ferrite core. Rather, you specify physical parameters like cross sectional area, core length and number of turns. The physical model of the magnetic device is defined by two vectors: magnetic field intensity H in A/m and magnetic flux density B (also known as magnetic induction) in Tesla. The default array values are:&lt;br /&gt;
   &lt;br /&gt;
H_array = [-250 -100 -50 -37.5 -25 -12.5 0 12.5 25 37.5 50 100 250]&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Insulated Gate Bipolar Transistor (IGBT) device with three pins: Collector(C), Gate (G), and Emitter (E). It is primarily used as a fast electronic switch. The IGBT combines the simple gate-drive characteristics of MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors. The device's model consists of an isolated gate FET for the control input, and a PNP bipolar power transistor as a switch.

&lt;br /&gt;
[[File:GK75.png]]&lt;br /&gt;
&lt;br /&gt;
This device is an interactive switch that can be closed or opened either directly from the Schematic Editor by clicking on its symbol or from the Instrument Panel.&lt;br /&gt;
&lt;br /&gt;
==Junction Field Effect Transistor (JFET)==&lt;br /&gt;
&lt;br /&gt;
[[File:G12.png]]&lt;br /&gt;
&lt;br /&gt;
The JFET is the simplest transistor device and has three pins: gate, drain and source. The JFET defaults are based on the Shichman and Hodges FET model. This is a square-law device because of the expression relating the drain current to the gate-to-source voltage: &lt;br /&gt;
Idrain=*(VGS-Vthreshold)2.  In real JFETs, near the saturation point, the drain currents vary with the drain voltages. This can be modeled by the following formula:  Idrain=*(VGS-VTO)2*(1+*VDS), which yields an increasing&lt;br /&gt;
drain current for increasing values of VDS.&lt;br /&gt;
&lt;br /&gt;
The gate-to-source and gate-to-drain junctions each have a nonlinear capacitor.  The zero-bias capacitance value is selected for each junction.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The CCCS is a current source whose current is directly proportional to the current across a controlling Ammeter or a voltage source. There are two versions: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Ammeter or voltage source, as well as the current gain, which has a default value of one. The four-terminal device already provides nodes for a controlling ammeter, and you just specify the current gain.   &lt;br /&gt;

==Lossless Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G21.png]]&lt;br /&gt;
&lt;br /&gt;
The lossless transmission line is a four-pin two-port device that models only one propagating mode of an ideal transmission line.  When using this SPICE model, should all four nodes of the actual circuit be distinct, two modes may be activated, and this device would be insufficient for that purpose. To circumvent this potential problem, two transmission line devices would be required. Due to the implementation details, you may produce more accurate simulation results with a lossy transmission line device with zero loss.&lt;br /&gt;
&lt;br /&gt;
Optional initial condition parameters are the voltage and current at each of the transmission line ports.&lt;br /&gt;
&lt;br /&gt;
The standard device parameters are Z0, TD, F, NL, IC, described below:&lt;br /&gt;
&lt;br /&gt;

The lossy transmission line is a four-pin two-port convolution model for uniform constant-parameter distributed lines. MNAME is the process model name, which&lt;br /&gt;

line), and RG (distributed series resistance and parallel conductance only) lines have been implemented. &lt;br /&gt;
The length (LEN) must be given.  COMPACTREL and COMPACTABS control the compaction of past history values&lt;br /&gt;
used in convolution.  Larger values for these lower accuracy but improve speed.  These are used with the&lt;br /&gt;
TRYTOCOMPACT option. &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
==Magnetic Core (XSPICE)==&lt;br /&gt;
&lt;br /&gt;
[[File:G42.png]]&lt;br /&gt;
&lt;br /&gt;
This device is used as a building block to create a wide variety of inductive and magnetic circuit models. It is almost always to be used in conjunction with the &amp;quot;lcouple&amp;quot; model to build up systems which simulate the behavior of linear and nonlinear magnetic components. There are two fundamental modes of operation for the core model. These are the &amp;quot;PWL&amp;quot; mode (which is the default and most&lt;br /&gt;
likely to be of use to you) and the &amp;quot;Hysteresis&amp;quot; mode.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;PWL Mode (mode = 1)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the PWL mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf) value. This value is divided by the total effective length of the core to produce a value for the Magnetic Field Intensity, H, which is then used to find the corresponding Flux Density, B, using the piecewise linear relationship described by you in the H_array / B_array coordinate pairs. B is then multiplied by the cross-sectional area of the core to find the Flux value, which is output as a current. The pertinent mathematical equations are:&lt;br /&gt;
&lt;br /&gt;
H = mmf / L, where L = Length (in apmere-turns/meter)&lt;br /&gt;
&lt;br /&gt;
B = f(H)&lt;br /&gt;
&lt;br /&gt;
&amp;amp;Phi; = B * A, where A = Area&lt;br /&gt;
&lt;br /&gt;
The B value is derived from a piecewise linear transfer function described to the model by the H_array and B_array coordinate pairs.  This transfer function does not include hysteretic effects; for that, you would need to substitute a HYST model for the core. The magnetic flux value &amp;amp;Phi; in turn is used by the &amp;quot;lcouple&amp;quot;&lt;br /&gt;
code model to obtain a value for the voltage reflected back across its terminals to the driving electrical circuit.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;b&amp;gt;Hysteresis Mode (mode = 2)&amp;lt;/b&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In the Hysteresis mode, the model takes a voltage as input which it treats as a magnetomotive force (mmf)&lt;br /&gt;
value.  This value is used as input to the equivalent of a hysteresis code model block.  The parameters&lt;br /&gt;
defining the input low and high values, the output low and high values, and the amount of hysteresis are&lt;br /&gt;
as in that model. The output from this mode, as in PWL mode, is a current value which is seen across the magnetic core port.&lt;br /&gt;
&lt;br /&gt;
One final note to be made about the two core models is that certain parameters are specific to one or the other.  In particular, the in_low, in_high, out_lower_limit, out_upper_limit, and hysteresis parameters are not available in PWL mode. Likewise, the H_array, B_array, area, ad length values are unavailable&lt;br /&gt;
in Hysteresis mode.  The input_domain and fraction parameters are common to both modes (though their behavior is somewhat different; for explanation of the input_domain and fraction values for the Hysteresis mode, please refer to the Hysteresis Block discussion.&lt;br /&gt;

[[File:G16.png]]&lt;br /&gt;
&lt;br /&gt;
The marker serves several purposes:&lt;br /&gt;
&lt;br /&gt;
* It can appear as a default plot in simulations if the &amp;amp;quot;Voltage Probe&amp;amp;quot; box is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to set the initial voltage or voltage guess at the node it is connected to.&lt;br /&gt;
&lt;br /&gt;
* It can be used as a port for a subcircuit when you choose the checkbox labeled &amp;quot;Use as Subcircuit Port&amp;quot; is checked.&lt;br /&gt;
&lt;br /&gt;
* It can be used to explicitly set a node number in place of the arbitrarily assigned node number by the program. In this case, make sure the &amp;amp;quot;Set Node Index&amp;amp;quot; box is checked.  Otherwise, it will act as just a voltage probe.&lt;br /&gt;
&lt;br /&gt;
* It can be used to connect different parts of a circuit in place of wires. To use markers as virtual connectors, place them at points where wires would otherwise connect. Then set the Part Title of the two (or more) markers to the same name, and they will act as a single circuit node.&lt;br /&gt;

==MESFET==&lt;br /&gt;
&lt;br /&gt;
[[File:G14.png]]&lt;br /&gt;
&lt;br /&gt;
The MESFET is a Schottky-barrier gate FET with six times greater electron mobility than silicon.  MESFETs are important devices for creating high frequency circuits. They function by creating a potential barrier between the gate and the channel when the metal gate&lt;br /&gt;
contacts the gallium-arsenide substrate. Electron velocity saturates for fields approximately ten times lower than with silicon.  The Curtice model includes linear and saturated operation.&lt;br /&gt;
&lt;br /&gt;
The standard parameters are AREA, OFF, IC, and T.  They are described below:&lt;br /&gt;

There are five different default models: square-law I-V characteristic, analytical, semi-empirical, and BSIM and BSIM2 (Berkeley Short-channel IGFET Model), which include second-order effects such as channel-length&lt;br /&gt;
modulation, subthreshold conduction, scattering-limited velocity saturation, small-size effects, and charge-controlled capacitance.  The process parameter LEVEL specifies which of the models is chosen as indicated below:&lt;br /&gt;

The mutual inductors device is a pair of inductors that are coupled to each other.  L1 and L2 are the names of two inductors. You have to specify the inductance of inductor L1, the inductance of inductor L2, the initial current through each, and the coupling coefficient k, 0 &amp;amp;le; k &amp;amp;le; 1. The mutual inductance M expressed in units of H can be calculated using the following definition:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt; k = \frac{M}{\sqrt{L_1 L_2}} &amp;lt;/math&amp;gt;&lt;br /&gt;

==Non-Ideal Current Transformer==&lt;br /&gt;

[[File:GK104.png]]&lt;br /&gt;
&lt;br /&gt;
This 8-pin device models a non-ideal lossy current transformer. Its model consists of an ideal transformer with more secondary turns than primary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. on each side of the internal ideal transformer, there is a series leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, followed by a shunt winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a series winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;, which connects to the exterior positive pin on that side. The inter-winding resistance R&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the negative pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance. &lt;br /&gt;

&lt;br /&gt;
This 2-pin device is a basic simplified model of a diode as a rectifier or switch. When forward-biased, it acts as a low-valued voltage source. When reverse-biased, it acts as an open circuit until the reverse voltage exceeds the specified breakdown voltage. Then it acts as a high-valued voltage source of the reverse polarity. &lt;br /&gt;

&lt;br /&gt;
This 8-pin device models a non-ideal lossy voltage transformer. Its model consists of an ideal transformer with more primary turns than secondary turns along with a number of parasitic elements. The interior pins with red wires give you direct access to the primary and secondary pins of the internal ideal transformer. There are series combinations of a winding resistance RW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; and a leakage inductance LL&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; on the primary and secondary sides. These are connected between the positive interior and exterior pins on each side. There are also two shunt branches at the inputs of the primary and secondary sides (connected between the positive and negative exterior pins), each consisting of a distributed turn-to-turn winding resistance RDC&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt; in series with a distributed turn-to-turn winding capacitance CW&amp;lt;sub&amp;gt;k&amp;lt;/sub&amp;gt;. The inter-winding capacitance CWW&amp;lt;sub&amp;gt;12&amp;lt;/sub&amp;gt; is connected across the positive pins of the primary and secondary of the ideal transformer model. In a more complete model, an external inductor LM can be connected between the positive and negative interior pins of either the primary or secondary to account for the effects of the magnetization inductance.  &lt;br /&gt;

==Nonlinear Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK89.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear capacitor model allows the capacitor to be described by an arbitrary relationship between the capacitor's charge Q and the voltage V across the capacitor. In other words, Q = f(V). The nonlinear capacitance is then defined as C(V) = dQ/dV. You need to define the charge Q by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ C_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear capacitor, where Q = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, C = C(V) = dQ/dV = C&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Conductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK88.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear conductor model allows the conductor to be described by an arbitrary relationship between the conductor's current I and the voltage V across the conductor. In other words, I = f(V). The nonlinear conductance is then defined as G(V) = dI/dV. You need to define the current I by a mathematical expression in the voltage V. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;v(pos,neg)&amp;quot; standing for the terminal voltage. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ G_DEF } * v(pos,neg)&lt;br /&gt;
&lt;br /&gt;
which implies a linear conductor, where I = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; V. Therefore, G = G(V) = dI/dV = G&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(v(pos,neg))^2.&lt;br /&gt;

==Nonlinear Dependent Sources==&lt;br /&gt;
&lt;br /&gt;
[[File:G18.png]]&lt;br /&gt;
&lt;br /&gt;
Nonlinear dependent (arbitrary) sources use an equation or mathematical expression to describe their behavior. One and only one of the two forms: V=&amp;amp;lt;expr&amp;amp;gt; or  I=&amp;amp;lt;expr&amp;amp;gt; must be given.&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; v = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
B&amp;lt;device_name&amp;gt; i = &amp;lt;expression&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Examples: &lt;br /&gt;
&lt;br /&gt;
v = I(v1) + 3* I(v2)&lt;br /&gt;
&lt;br /&gt;
I = v(i1) + 3* v(2) + 5 * v(3) ^2&lt;br /&gt;
&lt;br /&gt;
The first example is a current-controlled voltage source.  The v on the left side of the equation&lt;br /&gt;
indicates that it is a voltage source.  I(v1) and I(v2) are the currents through voltage sources named v1 and v2, respectively.&lt;br /&gt;
&lt;br /&gt;
The second example is a voltage-controlled current source.  v(2) and v(3) represents the voltages at nodes 2 and 3, respectively, and v(i1) represents the voltage across a current source named i1.&lt;br /&gt;
&lt;br /&gt;
The following mathematical functions defined for real variables can be used in the expressions:&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The function &amp;amp;quot;sgn&amp;amp;quot; is the signum function and its value is 1 if the argument is positive or zero and -1 if the argument is negative. &lt;br /&gt;
The function &amp;amp;quot;u(x)&amp;amp;quot; is the unit step and &amp;amp;quot;uramp(x)&amp;amp;quot; is the integral of the unit step.  The&lt;br /&gt;
unit step is one if its argument is greater than zero and zero if its argument is less than zero.  The&lt;br /&gt;
ramp function (uramp) is 0 for argument values less than zero and equal to the argument for argument values&lt;br /&gt;
greater than zero.&lt;br /&gt;
&lt;br /&gt;
The following operators are permissible:  +, -, *, /, and ^.&lt;br /&gt;
&lt;br /&gt;
The power functions have equivalent expressions: pwr(x,y) = x^y and pwrs(x,y) = sgn(x)*abs(x)^y.&lt;br /&gt;
&lt;br /&gt;
Two constants can also be used in expressions: pi = 3.1415926 and e = 2.7182818.&lt;br /&gt;
&lt;br /&gt;
There is a conditional function with the syntax IF(Condition, Expression1, Expression2). If &amp;quot;Condition&amp;quot; is met, then the return value of the function is Expression1; otherwise, it is Expression2. An example of this type of function is IF(v(1)&amp;gt;=0,1,-1), which is equivalent to sgn(v(1)). &lt;br /&gt;
&lt;br /&gt;
To get time into an expression, integrate the current from a constant current source with a capacitor&lt;br /&gt;
and use the voltage across the capacitor.&lt;br /&gt;

==Nonlinear Inductor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK90.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear inductor model allows the inductor to be described by an arbitrary relationship between the inductor's magnetic flux &amp;amp;Phi; and the current I flowing through the inductor . In other words, &amp;amp;Phi;  = f(I). The nonlinear inductance is then defined as L(I) = d&amp;amp;Phi;/dI. You need to define the flux &amp;amp;Phi; by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ L_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear inductor, where &amp;amp;Phi; = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, L = L(I) = d&amp;amp;Phi;/dI = L&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.  &lt;br /&gt;
&lt;br /&gt;
Another example is 1e-4*(i(vx))^2.&lt;br /&gt;

==Nonlinear Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK87.png]]&lt;br /&gt;
&lt;br /&gt;
The nonlinear resistor model allows the resistor to be described by an arbitrary relationship between the voltage V across the resistor and its current I. In other words, V = f(I). The nonlinear resistance is then defined as R(I) = dV/dI. You need to define the voltage V by a mathematical expression in the current I. You have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. Enter any mathematical expression in the variable &amp;quot;i(vx)&amp;quot; standing for the device current. The default expression is:&lt;br /&gt;
&lt;br /&gt;
{ R_DEF } * i(vx)&lt;br /&gt;
&lt;br /&gt;
which implies a linear resistor, where V = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt; I. Therefore, R = R(I) = dV/dI = R&amp;lt;sub&amp;gt;DEF&amp;lt;/sub&amp;gt;.&lt;br /&gt;
&lt;br /&gt;
Another example is 10*(i(vx))^2.&lt;br /&gt;

[[File:GK105.png]]&lt;br /&gt;
&lt;br /&gt;
This three-pin device models a parameterized operational amplifier with a very high voltage gain, a very high input impedance and a very low output impedance. The behavioral model of the parameterized Op-Amp device is based on the algorithm found in the book &amp;lt;B&amp;gt;Macromodeling with Spice&amp;lt;/B&amp;gt;,&lt;br /&gt;
authored by Connelly &amp;amp;amp; Choi, published by Prentice Hall. The default parameters are those of the 741 Op-Amp. This device doesn't require external DC bias voltage sources. Its positive and negative DC bias voltages are specified as its parameters. Sometimes the simulation doesn't converge if there is no DC path from the output of the Op-Amp to the ground.&lt;br /&gt;

== Optocoupler ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK115.png]]&lt;br /&gt;
&lt;br /&gt;
This is a five-pin parameterized optocoupler device. Its model consists of an ideal diode device in series with an Ohmic resistance connected between the Anode (A) and Cathode (K) pins together with a bipolar junction transistor device with three accessible pins, Collector (C), Base (B) and Emitter (E). A current-controlled current source is connected between base and collector of the BJT, whose current is controlled by the current passing through the diode. The proportionality constant is twice the specified value of the current transfer ratio (ctr) parameter. &lt;br /&gt;
&lt;br /&gt;
You can change or enhance the models of the diode and BJT by adding more parameters. To do so, you have to open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text. &lt;br /&gt;

[[File:GK113.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 4-pin parameterized photodiode device. A pair of pins, Anode (A) and Cathode (K), represent the physical terminals of the photodiode. The photodiode model connected between the anode and cathode pins consists of the parallel connection of an ideal diode, a dark current source, a noise current source, a current-controlled current source, a diode capacitance, a shunt resistance altogether with a series resistance.  &lt;br /&gt;
&lt;br /&gt;
Another pair of pins IS+ and IS- act as an ammeter that must be inserted in a control circuit. The current passing through this ammeter controls the current of the photodiode. The default proportionality constant is unity. The controlling current is typically a function of light intensity incident on the surface of the photodiode.    &lt;br /&gt;

==Piecewise Linear (PWL) Controlled Source==&lt;br /&gt;
&lt;br /&gt;
[[File:GL49.png]]&lt;br /&gt;
&lt;br /&gt;
The Piecewise Linear (PWL) Controlled Source is a single-input and single-output function generator whose output is not necessarily&lt;br /&gt;
linear for all input values. Instead, it follows an I/O relationship that is specified by the x_array and y_array coordinates. The x_array and y_array values represent vectors of coordinate points on the x and y axes, respectively. The x_array values are progressively increasing input coordinate points, and the associated y_array values represent the outputs at those points.  There may be as few as two pairs specified, or as many as memory and simulation speed allow.&lt;br /&gt;
&lt;br /&gt;
In order to fully specify outputs for values of Vin outside of the bounds of the PWL function, the PWL&lt;br /&gt;
controlled source model extends the slope found between the lowest two coordinate pairs and the highest&lt;br /&gt;
two coordinate pairs.  This has the effect of making the transfer function completely linear for Vin&lt;br /&gt;
less than x_array[0] and Vin greater than x_array[n]. It also has the potentially subtle effect of unrealistically&lt;br /&gt;
causing an output to reach a very large or small value for large inputs. You should thus keep in mind&lt;br /&gt;
that the PWL Source does not inherently provide a limiting capability.&lt;br /&gt;
&lt;br /&gt;
In order to diminish the potential for divergence of simulations when using the PWL block, a form&lt;br /&gt;
of smoothing around the x_array and y_array coordinate points is necessary.  This is due to the iterative&lt;br /&gt;
nature of the simulator and its reliance on smooth first derivatives of  transfer functions in order to&lt;br /&gt;
arrive at a matrix solution.  Consequently, the two parameters &amp;quot;input_domain&amp;quot; and &amp;quot;fraction&amp;quot; are included&lt;br /&gt;
to allow you some control over the amount and nature o the smoothing performed.&lt;br /&gt;
&lt;br /&gt;
Fraction is a switch that is either TRUE or FALSE.  When TRUE (the default setting), the simulator assumes&lt;br /&gt;
that the specified input_domain value is to be interpreted as a fractional figure.  Otherwise, it is interpreted&lt;br /&gt;
as an absolute value.  Thus, if fraction = TRUE and input_domain = 0.10, the simulator assumes that the smoothing&lt;br /&gt;
radius about each coordinate point is to be set equal to 10% of the length of either the x_array segment&lt;br /&gt;
above each coordinate point, or the x_array segment below each coordinate point. The specific segment&lt;br /&gt;
length chosen will be the smallest of these two for each coordinate point.&lt;br /&gt;
&lt;br /&gt;
If fraction = FALSE and input_domain = 0.10, then the simulator will begin smoothing the transfer function at 0.10&lt;br /&gt;
volts (or amperes) below each x_array coordinate and will continue the smoothing process for another 0.10&lt;br /&gt;
volts (or amperes) above each x_array coordinate point.&lt;br /&gt;

[[File:GK112.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin parameterized Programmable Unijunction Transistor (PUT) device with three pins: Base 1 (B1), Base 2 (B2) and Emitter (E). It is biased with a positive voltage between the two bases. This device has a unique characteristic that when it is triggered, its emitter current increases regeneratively until it is restricted by emitter power supply. It exhibits a negative resistance characteristic and so it can be employed as an oscillator. The device's model involves an NPN BJT and a PNP BJT. The forward beta parameters of the two transistors are set equal to 100 and 1, respectively. To change these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.    &lt;br /&gt;

This is primarily a non-ideal, temperature-dependent capacitor model. You can access it from the Parts Menu as '''User-Defined Capacitor'''. It has two temperature coefficients: first-order TC1 temperature and second-order TC2. The value of the temperature-dependent capacitance is computed using the quadratic equation:&lt;br /&gt;
&lt;br /&gt;
C(T) = C(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;
 &lt;br /&gt;
The device's model includes a series resistance and a series inductance together with the capacitor, all in parallel with a shunt resistance.&lt;br /&gt;

[[File:GK118.png]]&lt;br /&gt;
&lt;br /&gt;
This is primarily a non-ideal inductor model. You can access it from the Parts Menu as '''User-Defined Inductor'''. Its series resistor has two temperature coefficients: first-order TC1 temperature and second-order TC2. The value of the temperature-dependent resistance is computed using the quadratic equation:&lt;br /&gt;
&lt;br /&gt;
R(T) = R(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;
 &lt;br /&gt;

==Resistor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK119.png]]&lt;br /&gt;
&lt;br /&gt;
Resistors are passive devices that dissipate power. Their resistance value varies depending on how much power they can dissipate and is measured&lt;br /&gt;
in Ohms.  The transient, DC and AC behaviors of a resistor are all described by the same equation:&lt;br /&gt;
&lt;br /&gt;
v = R * i&lt;br /&gt;
&lt;br /&gt;
where v is the voltage across the resistor, i is the current passing through the resistor, and R is the resistance. The value of R must be nonzero. &lt;br /&gt;
&lt;br /&gt;
All resistor names must begin with R.&lt;br /&gt;

Example: &lt;br /&gt;
&lt;br /&gt;
R1 1 2 1k&lt;br /&gt;
&lt;br /&gt;
[[RF.Spice A/D]] provides three types of resistor: Simple, User-Defined (Real Resistor) and Semiconductor. The resistance of the simple resistor is a single value expressed in Ohms. You can also set the Monte Carlo tolerance for this resistor.&lt;br /&gt;
&lt;br /&gt;
==Schottky Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:GK80.png]]&lt;br /&gt;
&lt;br /&gt;
The Schottky diode has the same model as the generic diode with a nonzero transit time (tt), a nonzero junction capacitance (cjo) and a typically larger saturation current (is), a lower junction potential (vj) and a smaller grading coefficient (m).   &lt;br /&gt;
&lt;br /&gt;
==Semiconducting Capacitor==&lt;br /&gt;
&lt;br /&gt;
[[File:GK83.png]]&lt;br /&gt;
&lt;br /&gt;
This is the more general form of the Capacitor model and allows for the calculation of the actual capacitance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
CXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;IC=VAL&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it defines the capacitance. If MNAME is specified, then the capacitance is calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. Either VALUE or MNAME, LENGTH, and WIDTH may be specified, but not both sets. The optional initial condition &amp;quot;IC&amp;quot; is the initial voltage across the capacitor for transient simulations.&lt;br /&gt;
&lt;br /&gt;
The capacitance is computed as:&lt;br /&gt;
&lt;br /&gt;
CAP = CJ * (LENGTH - NARROW) * (WIDTH - NARROW)+ 2 * CJSW * (LENGTH + WIDTH - 2NARROW) * CAP&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the capacitor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit CJ, CJSW, NARROW, DEFW, and CAP.&lt;br /&gt;

&lt;br /&gt;
This is the more general form of the resistor model and allows for the modeling of temperature effects and for the calculation of the actual resistance value from strictly geometric information and the specifications of the process. &lt;br /&gt;
&lt;br /&gt;
General Form:&lt;br /&gt;
&lt;br /&gt;
RXXXXXXX N1 N2 &amp;lt;VALUE&amp;gt; &amp;lt;MNAME&amp;gt; &amp;lt;L=LENGTH&amp;gt; &amp;lt;W=WIDTH&amp;gt; &amp;lt;TEMP=T&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If VALUE is specified, it overrides the geometric information and defines the resistance. If MNAME is specified, then the resistance may be calculated from the process information in the model MNAME and the given LENGTH and WIDTH. If VALUE is not specified, then MNAME and LENGTH must be specified. If WIDTH is not specified, then it is taken from the default width given in the model. The (optional) TEMP value is the temperature at which this device is to operate, and overrides the temperature specification in the SPICE Options Dialog. &lt;br /&gt;
&lt;br /&gt;
The resistance is computed as:&lt;br /&gt;
&lt;br /&gt;
R(T0) = (RSH) * [(L - NARROW) / (W - NARROW)] * RES&lt;br /&gt;
&lt;br /&gt;
R(T) = R(T0) * [ 1 + TC1 * (T - T0) + TC2 * (T-T0)^2 ]&lt;br /&gt;
&lt;br /&gt;
To modify the model parameters, first double click on the resistor to edit its top-level model parameters. Then choose the button labeled {{key|Edit from Table}} in the process model section. This will open a window in which you can edit TC1, TC2, RSH, RES, etc.&lt;br /&gt;

&lt;br /&gt;
This is a 3-pin parameterized Silicon-Controlled Rectifier (SCR) device with three pins: Anode (A), Cathode (K) and Gate (G). It is a unidirectional device which can conduct current only in one direction. The SCR can be triggered only by a positive current going into its gate.

== Triac Thyristor ==&lt;br /&gt;
&lt;br /&gt;
[[File:GK110.png]]&lt;br /&gt;
&lt;br /&gt;
This is a 3-pin bidirectional thyristor device that conducts current in either direction when triggered. A thyristor is analogous to a relay in that a small voltage and current can control a much larger voltage and current. The triac has two anode pins termed Main Terminal 1 (MT1) and Main Terminal 2 (MT2) and a Gate (G) pin. In order to create a triggering current for a triac, either a positive or negative voltage can be applied to the gate. Once triggered, the thyristor continues to conduct, even if the gate current ceases, until the main current drops below a certain level called the holding current. The device's model involves two NPN BJT transistors and two PNP BJT transistors. The forward beta parameters of the NPN and PNP transistors are set equal to 20 and 5, respectively. To changes these values, open the subcircuit model dialog by clicking the {{key|View Subcircuit}} button and edit its text.&lt;br /&gt;

==Uniform RC Transmission Line==&lt;br /&gt;
&lt;br /&gt;
[[File:G23.png]]&lt;br /&gt;
&lt;br /&gt;
The standard parameters are L, and N.  They are described below:&lt;br /&gt;
&lt;br /&gt;
Two of the nodes are the element nodes connected by the RC line.  The third is the node to which the capacitances&lt;br /&gt;
are connected.  L is the length of the RC line in meters.  N is the number of lumped segments to use in&lt;br /&gt;
modeling the RC line.&lt;br /&gt;
&lt;br /&gt;
This device is derived from a model proposed by Gertzberrg.  It expands the URC line into a network of&lt;br /&gt;
lumped RC segments with internally generated nodes.  These segments increase toward the middle of the&lt;br /&gt;
URC line in a geometric progression with K as the proportionality constant.&lt;br /&gt;
&lt;br /&gt;
The URC line is made up entirely of resistor and capacitor segments, unless the ISPERL parameter has a&lt;br /&gt;
non-zero value.  In this case, capacitors are replaced by reverse biased diodes with an equivalent zero-bias&lt;br /&gt;
junction capacitance, a saturation current of ISPERL amps per meter of transmission line, and optional&lt;br /&gt;
series resistance of RSPERL ohms per meter. &lt;br /&gt;

==Voltage-Controlled Switch==&lt;br /&gt;
&lt;br /&gt;
[[File:G19.png]]&lt;br /&gt;
&lt;br /&gt;
Switches are devices that exhibit high resistance when open (OFF state) and low resistance when closed (ON state). The switch model allows an almost ideal switch to be specified. With careful selection of the on and off resistances, they can effectively represent zero and infinite resistances in comparison to other circuit elements, while sustaining the model condition of a positive, finite value. &lt;br /&gt;
&lt;br /&gt;
There are two versions of Voltage-Controlled Switch: two-terminal and four-terminal. For the two-terminal device, you must specify the name of the controlling Voltmeter or controlling voltage nodes, as well as the turn-on and turn-off voltages in Volts and on and off resistance values in Ohms. The four-terminal device already provides nodes for a controlling voltmeter, and you just specify the rest of [[parameters]]. When the voltage across the switch or controlling device is greater or equal to the turn-on current, the switch closes. When the voltage across the switch or controlling device is less than or equal to the turn off current, the switch opens. &lt;br /&gt;

==Voltage Source==&lt;br /&gt;
&lt;br /&gt;
[[File:G17A.png]]&lt;br /&gt;
&lt;br /&gt;
A voltage source has a DC value, a transient behavior, an AC behavior, and distortion parameters. The transient type, AC parameters, and distortion parameters are defined on the first tab of the source's property dialog. The transient expression can be a pulse, sinusoid, exponential, or piecewise linear. The DC value of a voltage source is its initial transient value. For a source with a sinusoidal transient behavior, for example, the DC value will be equal to its transient offset voltage. The AC parameters are magnitude and phase.  These are used during the AC Frequency Sweep analysis. The distortion parameters, two sets of magnitude and phase, are used during the distortion analysis. The AC and distortion parameters are defined on the second tab of the source's property dialog.&lt;br /&gt;
&lt;br /&gt;
==XSpice Devices and their models==&lt;br /&gt;
&lt;br /&gt;
XSpice devices have the following form:&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 4pt  0pt  1px  0pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
A&amp;amp;lt;device_name&amp;amp;gt; &amp;amp;lt;node1&amp;amp;gt; &amp;amp;lt;node2&amp;amp;gt; ... &amp;amp;lt;model_name&amp;amp;gt;&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
e.g., A2 1  2  transfer_function&lt;br /&gt;
&lt;br /&gt;
Note that XSpice devices must start with the &amp;amp;quot;A&amp;amp;quot; designation, much as a resistor starts with&lt;br /&gt;
an &amp;amp;quot;R&amp;amp;quot;.  Some devices will have grouped (or vector) pins and are designated by being placed&lt;br /&gt;
inside square brackets.  In the example shown below, the 1 and 2 pins are grouped.  Pin 3 is not.  &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  0pt ; text-indent: 36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
A1 [1   2]  3 summer &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Some models will have voltage differential pairs of pins and will be denoted by a %vd( ).  In the following&lt;br /&gt;
example pins 1 and 4 are differential pairs, as well as pins 2 and 3.  Differential pairs must go between&lt;br /&gt;
parentheses (). &lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  0pt ; text-indent: 36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
A1 %vd(1   4)   %vd(2   3)  triangle &amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Refer to individual devices for more information.&lt;br /&gt;
&lt;br /&gt;
Each XSpice device will also have a model associated with it.  Each model will have the following form:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
.model &amp;amp;lt;model_name&amp;amp;gt; &amp;amp;lt;model_identifier&amp;amp;gt; {&amp;amp;lt;pname1 = pval1&amp;amp;gt;} {&amp;amp;lt;pname2 = pval2&amp;amp;gt;} &lt;br /&gt;
...&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;P CLASS=&amp;quot;syntaxstyle&amp;quot; STYLE=&amp;quot;font-size: 9pt ; margin: 0pt  0pt  1px  36pt ; font-family: 02070309020205020404,sans-serif; &amp;quot;&amp;gt;&lt;br /&gt;
e.g., .model transfer_function s_xfer  in_offset = 0.0  gain = 1.0&amp;lt;/P&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Model_name refers to the name given in the device line.  Model_identifier is an internal designation and&lt;br /&gt;
must be of an existing designation  Refer to each device's example for the correct designation. &lt;br /&gt;
&lt;br /&gt;
Parameter values are optional.  If they aren't specified, then the default will be used.  Some devices&lt;br /&gt;
have parameters that require a value and must be specified.  Refer to individual devices for any required parameters.&lt;br /&gt;
&lt;br /&gt;
==Zener Diode==&lt;br /&gt;
&lt;br /&gt;
[[File:G10.png]]&lt;br /&gt;
&lt;br /&gt;
The Zener Diode models the DC characteristics of most zeners. Since most data sheets for zener diodes do&lt;br /&gt;
not give detailed characteristics in the forward region, only a single point defines the forward characteristicThe&lt;br /&gt;
saturation current refers to the relatively constant reverse current that is produced when the voltage&lt;br /&gt;
across the zener is negative, but breakdown has not been reached.  The reverse leakage current determines&lt;br /&gt;
the slight increase in reverse current as the voltage across the zener becomes more negative.  It is modeled&lt;br /&gt;
as a resistance parallel to the zener with value v_breakdown / i_rev.&lt;br /&gt;
&lt;br /&gt;
Note that the limt_switch parameter engages an internal limiting function for the zener.  This can, in&lt;br /&gt;
some cases, prevent the simulator from converging to an unrealistic solution if the voltage across or&lt;br /&gt;
current into the device is excessive.  If use of this feature fails to yield acceptable results, the convlimit&lt;br /&gt;
option should be tried (add the following statement to the SPICE input deck:  .options convlimit)&lt;br /&gt;
&lt;br /&gt;
Model Identifier: zener&lt;br /&gt;
&lt;br /&gt;
Netlist Format:&lt;br /&gt;
&lt;br /&gt;
A&amp;amp;lt;device_name&amp;amp;gt; &amp;amp;lt;z_pin&amp;amp;gt; &amp;amp;lt;z_out_pin&amp;amp;gt; &amp;amp;lt;model_name&amp;amp;gt;&lt;br /&gt;
&lt;br /&gt;
.model &amp;amp;lt;model_name&amp;amp;gt; zener v_breakdown = 1 {&amp;amp;lt;param1 = value&amp;amp;gt; &amp;amp;lt; param2 = value&amp;amp;gt; ...}&lt;br /&gt;
&lt;br /&gt;
Example:&lt;br /&gt;
&lt;br /&gt;
A1 1  2 zener&lt;br /&gt;
&lt;br /&gt;
.model zener zener  v_breakdown = 1&lt;br /&gt;

&lt;div&gt;== Overview ==&lt;br /&gt;
&lt;br /&gt;
=== General Overview ===&lt;br /&gt;
&lt;br /&gt;
Ver 1&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]]® real-time field measurement and scanning system is a turnkey, electric or magnetic field probe and measurement system. It can be configured as a near-field scanning system for mapping aperture-level field distributions with minimal invasiveness to the device or system under test. Or it can be used as a real-time field probe system for sensing or detecting electric and magnetic fields in a variety of media.&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system can be used as an essential tool for test and evaluation of antennas and phased array systems and is particularly useful for phase characterization and calibration. Unlike conventional near-field scanning systems that utilize metallic radiators to pick up the fields, [[NeoScan]] probes are non-metallic, operating based on electro-optic (EO) or magneto-optic (MO) effects. Its field probes feature extremely small EO or MO crystals mounted at the tip of an optical fiber. The combination of the small probe size and absolutely non-metallic parts leads to the ultimate radio frequency (RF) non-invasiveness.&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]] provides detailed field maps of passive and active devices and circuits including RFIC’s and MMIC’s. Such invaluable information can effectively be used for design validation, model verification, diagnostics and fault isolation or performance evaluation of various parts of RF systems. It is also an alternative compact range for measurement of far-field radiation patterns of antennas and arrays, dispensing with a costly anechoic chamber. The system can be used in real-time, polarimetric and coherent sensing and probing of wideband signals and pulses, EMC/EMI testing, and medical device measurements and characterization of biological environments. The [[NeoScan]] system can be configured in a multi-channel architecture for simultaneous field measurement at multiple points and locations. Different channels can measure different polarizations in a coherent manner.     &lt;br /&gt;
&lt;br /&gt;

=== General Description ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] real-time field measurement &amp;amp; scanning system provides an entirely new capability for the measurement of high-intensity electric fields. This technology is based on the Pockel’s effect which measures the phase-retardance of an optical beam due to an impinging electric field. This electro-optic effect is observed in non-centrosymmetric crystals when an electric field is directed along certain crystal axes causes a change in the indices of refraction encountered by an incident optical beam. Figure 1.1 shows the basic principle of the electro-optic effect. The electro-optic effect provides a means of modulating the phase or intensity of the optical radiation. In another sense, this effect also makes it possible to detect the presence of an electric field impinging on the crystal. The polarization of an optical beam travelling through a crystal is altered by the electric field in that crystal. The comparison of polarization states allows determination of the amplitude and phase of the existing RF electric field. Since the electro-optic sensing phenomenon relies on small displacements of the atomic crystal structure, the response time of the process is extremely short. This short response time makes it possible to measure high-frequency electric fields up to the terahertz regime.  &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_1_1.png|thumb|center|400px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 1.1&amp;lt;/b&amp;gt;: EO modulation of an optical signal.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A typical EO probe is composed of an optical fiber affixed with an EO crystal coated with a dielectric reflection layer on its bottom surface as shown in Figure 1.2. These probes have very delicate optical interconnects and extreme care must be taken in handling the probes to prevent excessive shock, bending and out of plane stresses.&lt;br /&gt;
&lt;br /&gt;
Due to its broad measurement bandwidth and high spatial resolution, the EO measurement technique is a promising means to characterize RF systems such as microwave and millimeter-wave integrated circuits, HPM sources and systems, and large-scale active arrays and other radiating structures. Unlike the conventional electrical measurement techniques which require some type of metal structure for the resonant detection of an RF signal, [[NeoScan]]’s unique real-time EO electric field measurement method requires no metal components. As a result, the field perturbation caused by introducing metal within the vicinity of a device under test (DUT) is significantly reduced.&lt;br /&gt;
&lt;br /&gt;
Figure 1.3 shows the electric and magnetic fields distribution of a traveling RF wave with a normal probe shown in typical orientation. To detect the maximum electric field in this configuration, the propagation direction of the optical beam of the probe should be parallel to the E-field direction. In general, a normal EO probe is only sensitive to the electric field component parallel to the probe handle, whereas a tangential probe is sensitive to the electric field component perpendicular to the probe handle. Yet, the E-field sensitivity of a tangential probe depends on its crystal orientation sitting on its tip. &lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;

The normal probe is oriented with the probe normal to direction of propagation.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A low noise 1550 nm laser diode is used as optical beam source. The optical connections are fiber-based. The beam is delivered to an optical probe. The polarization of the beam is modulated through an electro-optic crystal on the probe tip. The modulated beam is reflected back into the fiber, and back to the mainframe for analysis. An optical analyzer converts the polarization change of the beam into an amplitude change. The amplitude is linearly proportional to the strength of the external electric field at the probe-crystal location. The equation E=αV is used to calculate the electric field, where α is the calibration factor, or the slope between the electric field E (in V/m) and the measured EO signal V (in V/m/uV). For instance, for a calibration factor of 1.082 V/m/uV. a measured EO signal of 1000 uV (0.001 V), corresponds to and electric field of 1.082 V/m/uV x 1000 V = 1082 V/m.&lt;br /&gt;
&lt;br /&gt;

The upper trace shown on the oscilloscope is the input signal, and the lower trace is the measured signal.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Due to the fast response of the EO crystal, it is possible to measure extremely high-bandwidth signals with the normal SNR limitations of wideband signal detection. Using this capability, EMAG Technologies Inc. has developed the world’s first fiber-based real-time polarimetric electric field sensor system – [[NeoScan]] – for the measurement of high-power microwave signals. Figure 1.4 is an example of a real time measurement of a 6.6 nsec pulse with 10 kV/m peak field strength. The upper trace shown on the oscilloscope is the received signal, and the lower trace is the detected signal. &lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system is capable of measuring signals with bandwidths up to 20 GHz and signal levels as low as 1 V/m for optical probes with a 10 m PM fiber. Because the optical probes are free of metallic parts, it is possible to measure extremely high-field strengths since there are no free electron surfaces to generate arcing. The [[NeoScan]] can measure fields up at least 2 MV/m and possibly higher.&lt;br /&gt;
&lt;br /&gt;
=== System Overview ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] real-time field measurement and scanning system consists of: &lt;br /&gt;
&lt;br /&gt;

&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The power switch on the back will turn the system and the laser on or off. It is recommended to turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. A USB port is used to communicate with control computer. The “Signal Out” channels can be used for real-time measurements. The RF signal can be displayed either on a high resolution oscilloscope or a spectrum analyzer. The channels can also be configured for near-field scanning measurement with a U-jumper SMA Cables. The scanning configuration can measure both amplitude and the phase of the signal with a Lock-in Amplifier. &lt;br /&gt;

&lt;br /&gt;
=== Shipping &amp;amp; Handling Precautions ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system contains extremely sensitive and fragile components. Use extreme caution whenever operating this system. Do not attempt to service or adjust or install substitute parts to its components. Please contact EMAG Technologies Inc. for service and more information. &lt;br /&gt;
&lt;br /&gt;
In spite of its sophisticated capabilities, the [[NeoScan]] system is easy to learn and operate. You can start using the system within hours. Below are the procedures to help you get started using [[NeoScan]]. We highly recommend that you complete chapters 2 and 3 of [[NeoScan]] and familiarize yourself with its basic functions before attempting to run the system. Turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. Before getting started, consider the following precautions:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;The system operates from a 100V or 120V nominal AC power source having a line frequency of 50 or 60 Hz. Before connecting the power cord to a power source, verify that the AC input voltage value is correct.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;[[NeoScan]] real-time field measurement and scanning system contains a 40 mW laser diode emitting Class 3B laser radiation at ~1550 nm. The direct output power from the fiber port of each probe channel on the front panel is less than 10 mW. The beam at 1550 nm is invisible to human being and the invisible beam can be hazardous if directed at the eye. Direct exposure of eye to the invisible laser beam must be avoided.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;The fans in [[NeoScan]] optical mainframe are required to maintain proper operation. Do not block the vents in the frame box.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;In order to avoid EMC/EMI effect, keep the [[NeoScan]] box as far away from the DUT as possible.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt; &lt;br /&gt;
	&amp;lt;p&amp;gt;Follow standard electrostatic-discharge precaution, including grounding yourself prior to making cable connections to the system. A ground strap provides the most effective grounding and minimizes the likelihood of electrostatic damage.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Handle the probes and the PM fibers with extreme care. &amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Gently clean and attach the appropriate fiber connectors to the correct fiber port of the [[NeoScan]] system.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not excessively pull or bend the fiber.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;The probe tip is extremely fragile. Do not strike the probe tip. Always keep the probes in a safe place. &amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Keep the cables and the fibers handy in safe positions, but out of the way and untangled.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Always use an SMA torque wrench when connecting the SMA connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not over-torque the microwave SMA connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not over-tighten the optical connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Installing the [[NeoScan]] System ===&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]] optical mainframe is enclosed in a 4U case with dimensions of 24”(H) x 17”(L) x 13” (W) (61cm x 43cm x 33cm). The instrument weighs 60 pounds (27kg) and contains the entire optical system, control systems, and power conditioning circuits required for electric field measurements. It is packaged in foam. Open the cardboard box and remove the layers of foam. Care must be taken to ensure the optical connectors, the SMA connectors, and the USB connectors on the rear panel are not damaged. Remove the fiber port protection caps and keep safe for reuse when repacking the instrument. The instrument box should contain the corresponding power cord, cables and etc. &lt;br /&gt;
&lt;br /&gt;
Unpack the control computer (surface) and the computer holder. Attach the computer holder to the [[NeoScan]] front panel with the screws. Pull up the Holder Lock part on the top left. Place the control computer inside the computer holder. Pull down the Holder Lock part and lock it (Figure 2.1)&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_1.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.1&amp;lt;/b&amp;gt;: Installing NeoScan control computer.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Installing [[NeoScan]] Translation Stage ===&lt;br /&gt;
&lt;br /&gt;
Unpack the [[NeoScan]] translation stage components. To install (see Appendix A-l):&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the Y Linear Translation Stage on a stable flat table, preferably an optical table.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the X Linear Translation Stage on the Y Linear Translation Stage using four screws as shown by red screws in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the Plate on the X Linear Translation Stage. Fasten its four edges with screws as indicated by green arrows in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the X, Y, and Z Miniature Translation Stages on the front edge of the Optical Plate and fasten its four edges with screws as indicated by arrows in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Attach the Plastic Probe Fixture to the XYZ Miniature Translation Stage.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_2.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.2&amp;lt;/b&amp;gt;: Installing NeoScan Translation Stage.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Unpacking the EO Probes ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] probes are extremely sensitive and fragile components. Use extreme caution whenever operating them. EO probes have been packed in separate boxes (Figure 2.3). The probes are delicate, care must be taken to ensure that the fiber and probe tip are not bent hard or dropped. The probe heads are placed in foam and the probes are housed in a box surrounded by bubble wrap on all sides.&lt;br /&gt;
&lt;br /&gt;
To unpack, open the box top. Remove the visible bubble wrap and remove the entire foam structure from the box. Cut the tape holding the foam structure halves together and remove the top. Remove any bubble wrap in the foam structure. Remove the cardboard covering the probe tip and any small pieces of foam holding the EO Probe down in the foam. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
&amp;lt;table&amp;gt;&lt;br /&gt;
&amp;lt;tr&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_4.png|thumb|center|500px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.4&amp;lt;/b&amp;gt;: How to remove a probe from foam and holding an EO probe and the PM fiber.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
To remove a probe and the fiber from the box: &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Carefully press the both sides of the foam near the probe head, carefully un-wedge the probe from its slot, and then lift the probe. Figure 2.4 shows a picture how to remove a probe.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Carefully remove the probe from the foam, making sure to grasp the probe glass tube and not the probe tip, as this may damage the EO probe.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;While holding the probe from its glass tube and keep the fiber sheath in your hand, avoid stretching the white plastic shield part of the fiber. Do not pull the plastic shield part hard.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Handling the Probes and the Fibers ===&lt;br /&gt;
&lt;br /&gt;
The Probes and the fibers are made of a very pure, sensitive, and expensive materials. Treat them with care. Unwind a fiber gently and work out any tangles carefully. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT pull hard the fiber.&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT bend the fiber to a radius smaller than 4” (10 cm).&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT strike the probe tip. &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Remove the protective cap on the optical fiber cable connector. Connectors should be cleaned before interconnection. Any dirt or contamination can damage the connector or degrade performance. In other words, fiber optic connectors should to be cleaned every time they are mated and unmated. Use a dry cleaning cloth (reel-based cassette cleaner) to remove dirt, dust, and oil from connector end faces (Figure 2.5). You can also carefully clean a dirty fiber connector with isopropyl alcohol (IPA) and then dry with FIS fiber optic cleaner.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_5.png|thumb|center|600px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.5&amp;lt;/b&amp;gt;: Cleaning a connector end face using a dry cleaning cloth reel-based cassette cleaner.&amp;lt;/i&amp;gt;]] &lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Connecting the Probe to [[NeoScan]] Optical Mainframe ===&lt;br /&gt;
&lt;br /&gt;
The probe is coupled with a 10-meter-long PM fiber and connects to the optical mainframe with a FC/APC optical fiber connector. Remove the APC protection caps and keep safe for reuse when repacking the instrument. Gently clean and attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system. There is a pre-aligned (slow or fast axis) adjustable key connectors for the PM axis alignment across a connection. Make sure the key is aligned in the slot properly before tightening, see Figure 2.6.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_6.png|thumb|center|600px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.6&amp;lt;/b&amp;gt;: PM Fiber Optics and Connectors.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Quick Test of the [[NeoScan]] System ===&lt;br /&gt;
&lt;br /&gt;
As a quick system test:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Plug in the [[NeoScan]] optical mainframe power cord into an electrical receptacle and turn it on.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect control computer AC power adapter and turn on the control computer.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect USB multi-port Hub AC power adapter to the power.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect the [[NeoScan]] Optical Mainframe USB Interface Port on the rear panel to a port on the USB Hub, then connect the control computer USB Interface Port to another port on the USB Hub. The USB Hub is a plug and play device.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system (Probe 1, Probe 2, or Probe 3), see section 2.6.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;[[Image:icon_OBM.png|right|]] Open the [[NeoScan]] Optical Bench Manager program. The [[NeoScan]] Optical Bench Manager program is a Labview-Based System Operation which monitors the system status and the total return and polarization optical powers (see section 3.1 for more details). It is accessible through the desktop or Windows Explorer by double clicking on NeoScanOBM icon [[Image:icon_OBM_small.png]] as shown in Figure 2.7. The program will start running as shown in Figure 2.8.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_7.png|thumb|center|500px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.7&amp;lt;/b&amp;gt;: NeoScan Program Group in or Windows Explorer.&amp;lt;/i&amp;gt;]] &lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
When the program starts, the system should detect the total return power and polarization power and display their graphs over time and show their numerical values in mW, see Figure 2.8. The green “Probe Detected” indicator light will indicate that the probe is connected to the correct channel. Otherwise, if either the total return power or the polarization power is too low (less than 0.3 mW), the information panel will remind the users to correct the problem. This can be the case if the probe is not connected or is defective or there is a problem with the [[NeoScan]] system (Figure 2.9). Select the channel number you want to check using the dropdown list labeled “Select Channel.”&lt;br /&gt;
&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Deploying the Probe on a Probe Fixture ===&lt;br /&gt;
&lt;br /&gt;
During the scan or optimization process, the probe will be mounted on a plastic probe fixtures. The plastic probe fixtures has been mounted on translation stage by a single cap screw and holds the probe (Figure 2.10). The probe is positioned inside the gap located on probe holder and is secured by a cap which is fastened by screws as shown in Figure 2.11.&lt;br /&gt;
 &lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_10.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.10&amp;lt;/b&amp;gt;: Mounting the plastic probe fixtures on a moving translation stage.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Set up the 2-axis translation stage on a stable flat table, an optical table is preferred.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the plastic probe fixtures on the Z linear translation stage using the screw.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Loosen all screws of the cubic probe holder. Lift the cap and rest the probe holder on a flat horizontal flat surface. Gently insert the probe into the gap in the plastic probe holder in such a way that that about 0.6” (1.5cm) of the probe comes out from the either ends of the gap (Figure 2.11).&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;While the probe is sitting inside the gap, place the cap on the probe holder and secure it by fastening the four plastic screws. Make sure it is tight is enough so that the probe does not slip out of the gap. Yet, do not tighten hard since it may break the probe glass. Tighten the screws until you feel that you are not able to rotate the probe by your fingers.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the cube holder inside the probe fixture head in such a way that the probe passes through the existing hole (Figure 2.12). Make sure the probe does not hit the edges of the hole, otherwise, it may break and the crystal may fall off.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;To avoid bending the soft plastic shield of the fiber, pass the fiber through the top of the probe fixture using regular (Scotch) adhesive tapes as shown in Figure 2.13.&amp;lt;/p&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Important: When pulling out the probe from the hole, make sure the probe is positioned vertically and the probe tip does not touch the edges of the hole.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_11.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.11&amp;lt;/b&amp;gt;: Placing the probe inside the probe holder.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_12.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.12&amp;lt;/b&amp;gt;: Inserting the probe holder inside the probe fixture head.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Two black markers on the tangential probe indicate the E-field sensitivity direction (probes’ polarization direction). They should be oriented along the electric field in order to detect the maximum signal, see Figure 2.14.&lt;br /&gt;
&lt;br /&gt;

&lt;div&gt;== Overview ==&lt;br /&gt;
&lt;br /&gt;
=== General Overview ===&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]]® real-time field measurement and scanning system is a turnkey, electric or magnetic field probe and measurement system. It can be configured as a near-field scanning system for mapping aperture-level field distributions with minimal invasiveness to the device or system under test. Or it can be used as a real-time field probe system for sensing or detecting electric and magnetic fields in a variety of media.&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system can be used as an essential tool for test and evaluation of antennas and phased array systems and is particularly useful for phase characterization and calibration. Unlike conventional near-field scanning systems that utilize metallic radiators to pick up the fields, [[NeoScan]] probes are non-metallic, operating based on electro-optic (EO) or magneto-optic (MO) effects. Its field probes feature extremely small EO or MO crystals mounted at the tip of an optical fiber. The combination of the small probe size and absolutely non-metallic parts leads to the ultimate radio frequency (RF) non-invasiveness.&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]] provides detailed field maps of passive and active devices and circuits including RFIC’s and MMIC’s. Such invaluable information can effectively be used for design validation, model verification, diagnostics and fault isolation or performance evaluation of various parts of RF systems. It is also an alternative compact range for measurement of far-field radiation patterns of antennas and arrays, dispensing with a costly anechoic chamber. The system can be used in real-time, polarimetric and coherent sensing and probing of wideband signals and pulses, EMC/EMI testing, and medical device measurements and characterization of biological environments. The [[NeoScan]] system can be configured in a multi-channel architecture for simultaneous field measurement at multiple points and locations. Different channels can measure different polarizations in a coherent manner.     &lt;br /&gt;

=== General Description ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] real-time field measurement &amp;amp; scanning system provides an entirely new capability for the measurement of high-intensity electric fields. This technology is based on the Pockel’s effect which measures the phase-retardance of an optical beam due to an impinging electric field. This electro-optic effect is observed in non-centrosymmetric crystals when an electric field is directed along certain crystal axes causes a change in the indices of refraction encountered by an incident optical beam. Figure 1.1 shows the basic principle of the electro-optic effect. The electro-optic effect provides a means of modulating the phase or intensity of the optical radiation. In another sense, this effect also makes it possible to detect the presence of an electric field impinging on the crystal. The polarization of an optical beam travelling through a crystal is altered by the electric field in that crystal. The comparison of polarization states allows determination of the amplitude and phase of the existing RF electric field. Since the electro-optic sensing phenomenon relies on small displacements of the atomic crystal structure, the response time of the process is extremely short. This short response time makes it possible to measure high-frequency electric fields up to the terahertz regime.  &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_1_1.png|thumb|center|400px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 1.1&amp;lt;/b&amp;gt;: EO modulation of an optical signal.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A typical EO probe is composed of an optical fiber affixed with an EO crystal coated with a dielectric reflection layer on its bottom surface as shown in Figure 1.2. These probes have very delicate optical interconnects and extreme care must be taken in handling the probes to prevent excessive shock, bending and out of plane stresses.&lt;br /&gt;
&lt;br /&gt;
Due to its broad measurement bandwidth and high spatial resolution, the EO measurement technique is a promising means to characterize RF systems such as microwave and millimeter-wave integrated circuits, HPM sources and systems, and large-scale active arrays and other radiating structures. Unlike the conventional electrical measurement techniques which require some type of metal structure for the resonant detection of an RF signal, [[NeoScan]]’s unique real-time EO electric field measurement method requires no metal components. As a result, the field perturbation caused by introducing metal within the vicinity of a device under test (DUT) is significantly reduced.&lt;br /&gt;
&lt;br /&gt;
Figure 1.3 shows the electric and magnetic fields distribution of a traveling RF wave with a normal probe shown in typical orientation. To detect the maximum electric field in this configuration, the propagation direction of the optical beam of the probe should be parallel to the E-field direction. In general, a normal EO probe is only sensitive to the electric field component parallel to the probe handle, whereas a tangential probe is sensitive to the electric field component perpendicular to the probe handle. Yet, the E-field sensitivity of a tangential probe depends on its crystal orientation sitting on its tip. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
&amp;lt;table&amp;gt;&lt;br /&gt;

provide nearly identical performance to a bare probe.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;

The normal probe is oriented with the probe normal to direction of propagation.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A low noise 1550 nm laser diode is used as optical beam source. The optical connections are fiber-based. The beam is delivered to an optical probe. The polarization of the beam is modulated through an electro-optic crystal on the probe tip. The modulated beam is reflected back into the fiber, and back to the mainframe for analysis. An optical analyzer converts the polarization change of the beam into an amplitude change. The amplitude is linearly proportional to the strength of the external electric field at the probe-crystal location. The equation E=αV is used to calculate the electric field, where α is the calibration factor, or the slope between the electric field E (in V/m) and the measured EO signal V (in V/m/uV). For instance, for a calibration factor of 1.082 V/m/uV. a measured EO signal of 1000 uV (0.001 V), corresponds to and electric field of 1.082 V/m/uV x 1000 V = 1082 V/m.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_1_4.png|thumb|center|480px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 1.4&amp;lt;/b&amp;gt;: An example of a real time measurement of a 6.6 nsec pulse with 10 kV/m peak field strength. The upper trace shown on the oscilloscope is the input signal, and the lower trace is the measured signal.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Due to the fast response of the EO crystal, it is possible to measure extremely high-bandwidth signals with the normal SNR limitations of wideband signal detection. Using this capability, EMAG Technologies Inc. has developed the world’s first fiber-based real-time polarimetric electric field sensor system – [[NeoScan]] – for the measurement of high-power microwave signals. Figure 1.4 is an example of a real time measurement of a 6.6 nsec pulse with 10 kV/m peak field strength. The upper trace shown on the oscilloscope is the received signal, and the lower trace is the detected signal. &lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system is capable of measuring signals with bandwidths up to 20 GHz and signal levels as low as 1 V/m for optical probes with a 10 m PM fiber. Because the optical probes are free of metallic parts, it is possible to measure extremely high-field strengths since there are no free electron surfaces to generate arcing. The [[NeoScan]] can measure fields up at least 2 MV/m and possibly higher.&lt;br /&gt;
&lt;br /&gt;
=== System Overview ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] real-time field measurement and scanning system consists of: &lt;br /&gt;

&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The power switch on the back will turn the system and the laser on or off. It is recommended to turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. A USB port is used to communicate with control computer. The “Signal Out” channels can be used for real-time measurements. The RF signal can be displayed either on a high resolution oscilloscope or a spectrum analyzer. The channels can also be configured for near-field scanning measurement with a U-jumper SMA Cables. The scanning configuration can measure both amplitude and the phase of the signal with a Lock-in Amplifier. &lt;br /&gt;

== NeoScan Probe Installation ==&lt;br /&gt;
&lt;br /&gt;
=== Shipping &amp;amp; Handling Precautions ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system contains extremely sensitive and fragile components. Use extreme caution whenever operating this system. Do not attempt to service or adjust or install substitute parts to its components. Please contact EMAG Technologies Inc. for service and more information. &lt;br /&gt;
&lt;br /&gt;
In spite of its sophisticated capabilities, the [[NeoScan]] system is easy to learn and operate. You can start using the system within hours. Below are the procedures to help you get started using [[NeoScan]]. We highly recommend that you complete chapters 2 and 3 of [[NeoScan]] and familiarize yourself with its basic functions before attempting to run the system. Turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. Before getting started, consider the following precautions:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;The system operates from a 100V or 120V nominal AC power source having a line frequency of 50 or 60 Hz. Before connecting the power cord to a power source, verify that the AC input voltage value is correct.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;[[NeoScan]] real-time field measurement and scanning system contains a 40 mW laser diode emitting Class 3B laser radiation at ~1550 nm. The direct output power from the fiber port of each probe channel on the front panel is less than 10 mW. The beam at 1550 nm is invisible to human being and the invisible beam can be hazardous if directed at the eye. Direct exposure of eye to the invisible laser beam must be avoided.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;The fans in [[NeoScan]] optical mainframe are required to maintain proper operation. Do not block the vents in the frame box.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;In order to avoid EMC/EMI effect, keep the [[NeoScan]] box as far away from the DUT as possible.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt; &lt;br /&gt;
	&amp;lt;p&amp;gt;Follow standard electrostatic-discharge precaution, including grounding yourself prior to making cable connections to the system. A ground strap provides the most effective grounding and minimizes the likelihood of electrostatic damage.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Handle the probes and the PM fibers with extreme care. &amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Gently clean and attach the appropriate fiber connectors to the correct fiber port of the [[NeoScan]] system.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not excessively pull or bend the fiber.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;The probe tip is extremely fragile. Do not strike the probe tip. Always keep the probes in a safe place. &amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Keep the cables and the fibers handy in safe positions, but out of the way and untangled.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Always use an SMA torque wrench when connecting the SMA connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not over-torque the microwave SMA connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not over-tighten the optical connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Installing the [[NeoScan]] System ===&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]] optical mainframe is enclosed in a 4U case with dimensions of 24”(H) x 17”(L) x 13” (W) (61cm x 43cm x 33cm). The instrument weighs 60 pounds (27kg) and contains the entire optical system, control systems, and power conditioning circuits required for electric field measurements. It is packaged in foam. Open the cardboard box and remove the layers of foam. Care must be taken to ensure the optical connectors, the SMA connectors, and the USB connectors on the rear panel are not damaged. Remove the fiber port protection caps and keep safe for reuse when repacking the instrument. The instrument box should contain the corresponding power cord, cables and etc. &lt;br /&gt;
&lt;br /&gt;
Unpack the control computer (surface) and the computer holder. Attach the computer holder to the [[NeoScan]] front panel with the screws. Pull up the Holder Lock part on the top left. Place the control computer inside the computer holder. Pull down the Holder Lock part and lock it (Figure 2.1)&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_1.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.1&amp;lt;/b&amp;gt;: Installing NeoScan control computer.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Installing [[NeoScan]] Translation Stage ===&lt;br /&gt;
&lt;br /&gt;
Unpack the [[NeoScan]] translation stage components. To install (see Appendix A-l):&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the Y Linear Translation Stage on a stable flat table, preferably an optical table.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the X Linear Translation Stage on the Y Linear Translation Stage using four screws as shown by red screws in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the Plate on the X Linear Translation Stage. Fasten its four edges with screws as indicated by green arrows in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the X, Y, and Z Miniature Translation Stages on the front edge of the Optical Plate and fasten its four edges with screws as indicated by arrows in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Attach the Plastic Probe Fixture to the XYZ Miniature Translation Stage.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_2.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.2&amp;lt;/b&amp;gt;: Installing NeoScan Translation Stage.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Unpacking the EO Probes ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] probes are extremely sensitive and fragile components. Use extreme caution whenever operating them. EO probes have been packed in separate boxes (Figure 2.3). The probes are delicate, care must be taken to ensure that the fiber and probe tip are not bent hard or dropped. The probe heads are placed in foam and the probes are housed in a box surrounded by bubble wrap on all sides.&lt;br /&gt;
&lt;br /&gt;
To unpack, open the box top. Remove the visible bubble wrap and remove the entire foam structure from the box. Cut the tape holding the foam structure halves together and remove the top. Remove any bubble wrap in the foam structure. Remove the cardboard covering the probe tip and any small pieces of foam holding the EO Probe down in the foam. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
&amp;lt;table&amp;gt;&lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
To remove a probe and the fiber from the box: &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Carefully press the both sides of the foam near the probe head, carefully un-wedge the probe from its slot, and then lift the probe. Figure 2.4 shows a picture how to remove a probe.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Carefully remove the probe from the foam, making sure to grasp the probe glass tube and not the probe tip, as this may damage the EO probe.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;While holding the probe from its glass tube and keep the fiber sheath in your hand, avoid stretching the white plastic shield part of the fiber. Do not pull the plastic shield part hard.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Handling the Probes and the Fibers ===&lt;br /&gt;
&lt;br /&gt;
The Probes and the fibers are made of a very pure, sensitive, and expensive materials. Treat them with care. Unwind a fiber gently and work out any tangles carefully. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT pull hard the fiber.&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT bend the fiber to a radius smaller than 4” (10 cm).&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT strike the probe tip. &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Remove the protective cap on the optical fiber cable connector. Connectors should be cleaned before interconnection. Any dirt or contamination can damage the connector or degrade performance. In other words, fiber optic connectors should to be cleaned every time they are mated and unmated. Use a dry cleaning cloth (reel-based cassette cleaner) to remove dirt, dust, and oil from connector end faces (Figure 2.5). You can also carefully clean a dirty fiber connector with isopropyl alcohol (IPA) and then dry with FIS fiber optic cleaner.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_5.png|thumb|center|600px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.5&amp;lt;/b&amp;gt;: Cleaning a connector end face using a dry cleaning cloth reel-based cassette cleaner.&amp;lt;/i&amp;gt;]] &lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Connecting the Probe to [[NeoScan]] Optical Mainframe ===&lt;br /&gt;
&lt;br /&gt;
The probe is coupled with a 10-meter-long PM fiber and connects to the optical mainframe with a FC/APC optical fiber connector. Remove the APC protection caps and keep safe for reuse when repacking the instrument. Gently clean and attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system. There is a pre-aligned (slow or fast axis) adjustable key connectors for the PM axis alignment across a connection. Make sure the key is aligned in the slot properly before tightening, see Figure 2.6.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_6.png|thumb|center|600px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.6&amp;lt;/b&amp;gt;: PM Fiber Optics and Connectors.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Quick Test of the [[NeoScan]] System ===&lt;br /&gt;
&lt;br /&gt;
As a quick system test:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Plug in the [[NeoScan]] optical mainframe power cord into an electrical receptacle and turn it on.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect control computer AC power adapter and turn on the control computer.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect USB multi-port Hub AC power adapter to the power.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect the [[NeoScan]] Optical Mainframe USB Interface Port on the rear panel to a port on the USB Hub, then connect the control computer USB Interface Port to another port on the USB Hub. The USB Hub is a plug and play device.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system (Probe 1, Probe 2, or Probe 3), see section 2.6.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;[[Image:icon_OBM.png|right|]] Open the [[NeoScan]] Optical Bench Manager program. The [[NeoScan]] Optical Bench Manager program is a Labview-Based System Operation which monitors the system status and the total return and polarization optical powers (see section 3.1 for more details). It is accessible through the desktop or Windows Explorer by double clicking on NeoScanOBM icon [[Image:icon_OBM_small.png]] as shown in Figure 2.7. The program will start running as shown in Figure 2.8.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
When the program starts, the system should detect the total return power and polarization power and display their graphs over time and show their numerical values in mW, see Figure 2.8. The green “Probe Detected” indicator light will indicate that the probe is connected to the correct channel. Otherwise, if either the total return power or the polarization power is too low (less than 0.3 mW), the information panel will remind the users to correct the problem. This can be the case if the probe is not connected or is defective or there is a problem with the [[NeoScan]] system (Figure 2.9). Select the channel number you want to check using the dropdown list labeled “Select Channel.”&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Deploying the Probe on a Probe Fixture ===&lt;br /&gt;
&lt;br /&gt;
During the scan or optimization process, the probe will be mounted on a plastic probe fixtures. The plastic probe fixtures has been mounted on translation stage by a single cap screw and holds the probe (Figure 2.10). The probe is positioned inside the gap located on probe holder and is secured by a cap which is fastened by screws as shown in Figure 2.11.&lt;br /&gt;
 &lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_10.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.10&amp;lt;/b&amp;gt;: Mounting the plastic probe fixtures on a moving translation stage.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Set up the 2-axis translation stage on a stable flat table, an optical table is preferred.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the plastic probe fixtures on the Z linear translation stage using the screw.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Loosen all screws of the cubic probe holder. Lift the cap and rest the probe holder on a flat horizontal flat surface. Gently insert the probe into the gap in the plastic probe holder in such a way that that about 0.6” (1.5cm) of the probe comes out from the either ends of the gap (Figure 2.11).&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;While the probe is sitting inside the gap, place the cap on the probe holder and secure it by fastening the four plastic screws. Make sure it is tight is enough so that the probe does not slip out of the gap. Yet, do not tighten hard since it may break the probe glass. Tighten the screws until you feel that you are not able to rotate the probe by your fingers.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the cube holder inside the probe fixture head in such a way that the probe passes through the existing hole (Figure 2.12). Make sure the probe does not hit the edges of the hole, otherwise, it may break and the crystal may fall off.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;To avoid bending the soft plastic shield of the fiber, pass the fiber through the top of the probe fixture using regular (Scotch) adhesive tapes as shown in Figure 2.13.&amp;lt;/p&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Important: When pulling out the probe from the hole, make sure the probe is positioned vertically and the probe tip does not touch the edges of the hole.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_11.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.11&amp;lt;/b&amp;gt;: Placing the probe inside the probe holder.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Two black markers on the tangential probe indicate the E-field sensitivity direction (probes’ polarization direction). They should be oriented along the electric field in order to detect the maximum signal, see Figure 2.14.&lt;br /&gt;

&lt;div&gt;== Overview ==&lt;br /&gt;
&lt;br /&gt;
=== General Overview ===&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]]® real-time field measurement and scanning system is a turnkey, electric or magnetic field probe and measurement system. It can be configured as a near-field scanning system for mapping aperture-level field distributions with minimal invasiveness to the device or system under test. Or it can be used as a real-time field probe system for sensing or detecting electric and magnetic fields in a variety of media.&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system can be used as an essential tool for test and evaluation of antennas and phased array systems and is particularly useful for phase characterization and calibration. Unlike conventional near-field scanning systems that utilize metallic radiators to pick up the fields, [[NeoScan]] probes are non-metallic, operating based on electro-optic (EO) or magneto-optic (MO) effects. Its field probes feature extremely small EO or MO crystals mounted at the tip of an optical fiber. The combination of the small probe size and absolutely non-metallic parts leads to the ultimate radio frequency (RF) non-invasiveness.&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]] provides detailed field maps of passive and active devices and circuits including RFIC’s and MMIC’s. Such invaluable information can effectively be used for design validation, model verification, diagnostics and fault isolation or performance evaluation of various parts of RF systems. It is also an alternative compact range for measurement of far-field radiation patterns of antennas and arrays, dispensing with a costly anechoic chamber. The system can be used in real-time, polarimetric and coherent sensing and probing of wideband signals and pulses, EMC/EMI testing, and medical device measurements and characterization of biological environments. The [[NeoScan]] system can be configured in a multi-channel architecture for simultaneous field measurement at multiple points and locations. Different channels can measure different polarizations in a coherent manner.     &lt;br /&gt;

=== General Description ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] real-time field measurement &amp;amp; scanning system provides an entirely new capability for the measurement of high-intensity electric fields. This technology is based on the Pockel’s effect which measures the phase-retardance of an optical beam due to an impinging electric field. This electro-optic effect is observed in non-centrosymmetric crystals when an electric field is directed along certain crystal axes causes a change in the indices of refraction encountered by an incident optical beam. Figure 1.1 shows the basic principle of the electro-optic effect. The electro-optic effect provides a means of modulating the phase or intensity of the optical radiation. In another sense, this effect also makes it possible to detect the presence of an electric field impinging on the crystal. The polarization of an optical beam travelling through a crystal is altered by the electric field in that crystal. The comparison of polarization states allows determination of the amplitude and phase of the existing RF electric field. Since the electro-optic sensing phenomenon relies on small displacements of the atomic crystal structure, the response time of the process is extremely short. This short response time makes it possible to measure high-frequency electric fields up to the terahertz regime.  &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_1_1.png|thumb|center|400px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 1.1&amp;lt;/b&amp;gt;: EO modulation of an optical signal.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A typical EO probe is composed of an optical fiber affixed with an EO crystal coated with a dielectric reflection layer on its bottom surface as shown in Figure 1.2. These probes have very delicate optical interconnects and extreme care must be taken in handling the probes to prevent excessive shock, bending and out of plane stresses.&lt;br /&gt;
&lt;br /&gt;
Due to its broad measurement bandwidth and high spatial resolution, the EO measurement technique is a promising means to characterize RF systems such as microwave and millimeter-wave integrated circuits, HPM sources and systems, and large-scale active arrays and other radiating structures. Unlike the conventional electrical measurement techniques which require some type of metal structure for the resonant detection of an RF signal, [[NeoScan]]’s unique real-time EO electric field measurement method requires no metal components. As a result, the field perturbation caused by introducing metal within the vicinity of a device under test (DUT) is significantly reduced.&lt;br /&gt;
&lt;br /&gt;
Figure 1.3 shows the electric and magnetic fields distribution of a traveling RF wave with a normal probe shown in typical orientation. To detect the maximum electric field in this configuration, the propagation direction of the optical beam of the probe should be parallel to the E-field direction. In general, a normal EO probe is only sensitive to the electric field component parallel to the probe handle, whereas a tangential probe is sensitive to the electric field component perpendicular to the probe handle. Yet, the E-field sensitivity of a tangential probe depends on its crystal orientation sitting on its tip. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;

provide nearly identical performance to a bare probe.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;

The normal probe is oriented with the probe normal to direction of propagation.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A low noise 1550 nm laser diode is used as optical beam source. The optical connections are fiber-based. The beam is delivered to an optical probe. The polarization of the beam is modulated through an electro-optic crystal on the probe tip. The modulated beam is reflected back into the fiber, and back to the mainframe for analysis. An optical analyzer converts the polarization change of the beam into an amplitude change. The amplitude is linearly proportional to the strength of the external electric field at the probe-crystal location. The equation E=αV is used to calculate the electric field, where α is the calibration factor, or the slope between the electric field E (in V/m) and the measured EO signal V (in V/m/uV). For instance, for a calibration factor of 1.082 V/m/uV. a measured EO signal of 1000 uV (0.001 V), corresponds to and electric field of 1.082 V/m/uV x 1000 V = 1082 V/m.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_1_4.png|thumb|center|480px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 1.4&amp;lt;/b&amp;gt;: An example of a real time measurement of a 6.6 nsec pulse with 10 kV/m peak field strength. The upper trace shown on the oscilloscope is the input signal, and the lower trace is the measured signal.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Due to the fast response of the EO crystal, it is possible to measure extremely high-bandwidth signals with the normal SNR limitations of wideband signal detection. Using this capability, EMAG Technologies Inc. has developed the world’s first fiber-based real-time polarimetric electric field sensor system – [[NeoScan]] – for the measurement of high-power microwave signals. Figure 1.4 is an example of a real time measurement of a 6.6 nsec pulse with 10 kV/m peak field strength. The upper trace shown on the oscilloscope is the received signal, and the lower trace is the detected signal. &lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system is capable of measuring signals with bandwidths up to 20 GHz and signal levels as low as 1 V/m for optical probes with a 10 m PM fiber. Because the optical probes are free of metallic parts, it is possible to measure extremely high-field strengths since there are no free electron surfaces to generate arcing. The [[NeoScan]] can measure fields up at least 2 MV/m and possibly higher.&lt;br /&gt;
&lt;br /&gt;
=== System Overview ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] real-time field measurement and scanning system consists of: &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
An optical mainframe with a touchscreen control computer that can be used for either real-time high power microwave measurement or E-field scanning as shown in Figure 1.5.&lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The power switch on the back will turn the system and the laser on or off. It is recommended to turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. A USB port is used to communicate with control computer. The “Signal Out” channels can be used for real-time measurements. The RF signal can be displayed either on a high resolution oscilloscope or a spectrum analyzer. The channels can also be configured for near-field scanning measurement with a U-jumper SMA Cables. The scanning configuration can measure both amplitude and the phase of the signal with a Lock-in Amplifier. &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;   &lt;br /&gt;
	One normal probe and two tangential probes&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;   &lt;br /&gt;
	One 2-axis translation stage with a stage controller for scanning operation (Figure 1.6)&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;   &lt;br /&gt;

	One GPIB-USB cable for instrument control&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;   &lt;br /&gt;
	One USB multi-port Hub for instrument control&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;   &lt;br /&gt;
	The [[NeoScan]] system control software package&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;   &lt;br /&gt;
&lt;br /&gt;
Additional equipment needed to configure [[NeoScan]] as a field scanning system include:&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;   &lt;br /&gt;
	A signal generator to provide the local oscillator (LO) signal for [[NeoScan]]’s output mixer&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;   &lt;br /&gt;
	A signal generator to provide a 100 MHz reference signal to lock-in amplifier &lt;br /&gt;

== NeoScan Probe Installation ==&lt;br /&gt;
&lt;br /&gt;
=== Shipping &amp;amp; Handling Precautions ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system contains extremely sensitive and fragile components. Use extreme caution whenever operating this system. Do not attempt to service or adjust or install substitute parts to its components. Please contact EMAG Technologies Inc. for service and more information. &lt;br /&gt;
&lt;br /&gt;
In spite of its sophisticated capabilities, the [[NeoScan]] system is easy to learn and operate. You can start using the system within hours. Below are the procedures to help you get started using [[NeoScan]]. We highly recommend that you complete chapters 2 and 3 of [[NeoScan]] and familiarize yourself with its basic functions before attempting to run the system. Turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. Before getting started, consider the following precautions:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;The system operates from a 100V or 120V nominal AC power source having a line frequency of 50 or 60 Hz. Before connecting the power cord to a power source, verify that the AC input voltage value is correct.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;[[NeoScan]] real-time field measurement and scanning system contains a 40 mW laser diode emitting Class 3B laser radiation at ~1550 nm. The direct output power from the fiber port of each probe channel on the front panel is less than 10 mW. The beam at 1550 nm is invisible to human being and the invisible beam can be hazardous if directed at the eye. Direct exposure of eye to the invisible laser beam must be avoided.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;The fans in [[NeoScan]] optical mainframe are required to maintain proper operation. Do not block the vents in the frame box.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;In order to avoid EMC/EMI effect, keep the [[NeoScan]] box as far away from the DUT as possible.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt; &lt;br /&gt;
	&amp;lt;p&amp;gt;Follow standard electrostatic-discharge precaution, including grounding yourself prior to making cable connections to the system. A ground strap provides the most effective grounding and minimizes the likelihood of electrostatic damage.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Handle the probes and the PM fibers with extreme care. &amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Gently clean and attach the appropriate fiber connectors to the correct fiber port of the [[NeoScan]] system.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not excessively pull or bend the fiber.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;The probe tip is extremely fragile. Do not strike the probe tip. Always keep the probes in a safe place. &amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Keep the cables and the fibers handy in safe positions, but out of the way and untangled.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Always use an SMA torque wrench when connecting the SMA connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not over-torque the microwave SMA connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not over-tighten the optical connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Installing the [[NeoScan]] System ===&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]] optical mainframe is enclosed in a 4U case with dimensions of 24”(H) x 17”(L) x 13” (W) (61cm x 43cm x 33cm). The instrument weighs 60 pounds (27kg) and contains the entire optical system, control systems, and power conditioning circuits required for electric field measurements. It is packaged in foam. Open the cardboard box and remove the layers of foam. Care must be taken to ensure the optical connectors, the SMA connectors, and the USB connectors on the rear panel are not damaged. Remove the fiber port protection caps and keep safe for reuse when repacking the instrument. The instrument box should contain the corresponding power cord, cables and etc. &lt;br /&gt;
&lt;br /&gt;
Unpack the control computer (surface) and the computer holder. Attach the computer holder to the [[NeoScan]] front panel with the screws. Pull up the Holder Lock part on the top left. Place the control computer inside the computer holder. Pull down the Holder Lock part and lock it (Figure 2.1)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== Installing [[NeoScan]] Translation Stage ===&lt;br /&gt;
&lt;br /&gt;
Unpack the [[NeoScan]] translation stage components. To install (see Appendix A-l):&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the Y Linear Translation Stage on a stable flat table, preferably an optical table.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the X Linear Translation Stage on the Y Linear Translation Stage using four screws as shown by red screws in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the Plate on the X Linear Translation Stage. Fasten its four edges with screws as indicated by green arrows in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the X, Y, and Z Miniature Translation Stages on the front edge of the Optical Plate and fasten its four edges with screws as indicated by arrows in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Attach the Plastic Probe Fixture to the XYZ Miniature Translation Stage.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== Unpacking the EO Probes ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] probes are extremely sensitive and fragile components. Use extreme caution whenever operating them. EO probes have been packed in separate boxes (Figure 2.3). The probes are delicate, care must be taken to ensure that the fiber and probe tip are not bent hard or dropped. The probe heads are placed in foam and the probes are housed in a box surrounded by bubble wrap on all sides.&lt;br /&gt;
&lt;br /&gt;
To unpack, open the box top. Remove the visible bubble wrap and remove the entire foam structure from the box. Cut the tape holding the foam structure halves together and remove the top. Remove any bubble wrap in the foam structure. Remove the cardboard covering the probe tip and any small pieces of foam holding the EO Probe down in the foam. &lt;br /&gt;
&lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
To remove a probe and the fiber from the box: &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Carefully press the both sides of the foam near the probe head, carefully un-wedge the probe from its slot, and then lift the probe. Figure 2.4 shows a picture how to remove a probe.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Carefully remove the probe from the foam, making sure to grasp the probe glass tube and not the probe tip, as this may damage the EO probe.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;While holding the probe from its glass tube and keep the fiber sheath in your hand, avoid stretching the white plastic shield part of the fiber. Do not pull the plastic shield part hard.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Handling the Probes and the Fibers ===&lt;br /&gt;
&lt;br /&gt;
The Probes and the fibers are made of a very pure, sensitive, and expensive materials. Treat them with care. Unwind a fiber gently and work out any tangles carefully. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT pull hard the fiber.&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT bend the fiber to a radius smaller than 4” (10 cm).&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT strike the probe tip. &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Remove the protective cap on the optical fiber cable connector. Connectors should be cleaned before interconnection. Any dirt or contamination can damage the connector or degrade performance. In other words, fiber optic connectors should to be cleaned every time they are mated and unmated. Use a dry cleaning cloth (reel-based cassette cleaner) to remove dirt, dust, and oil from connector end faces (Figure 2.5). You can also carefully clean a dirty fiber connector with isopropyl alcohol (IPA) and then dry with FIS fiber optic cleaner.&lt;br /&gt;
&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Connecting the Probe to [[NeoScan]] Optical Mainframe ===&lt;br /&gt;
&lt;br /&gt;
The probe is coupled with a 10-meter-long PM fiber and connects to the optical mainframe with a FC/APC optical fiber connector. Remove the APC protection caps and keep safe for reuse when repacking the instrument. Gently clean and attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system. There is a pre-aligned (slow or fast axis) adjustable key connectors for the PM axis alignment across a connection. Make sure the key is aligned in the slot properly before tightening, see Figure 2.6.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_6.png|thumb|center|600px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.6&amp;lt;/b&amp;gt;: PM Fiber Optics and Connectors.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Quick Test of the [[NeoScan]] System ===&lt;br /&gt;
&lt;br /&gt;
As a quick system test:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Plug in the [[NeoScan]] optical mainframe power cord into an electrical receptacle and turn it on.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect control computer AC power adapter and turn on the control computer.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect USB multi-port Hub AC power adapter to the power.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect the [[NeoScan]] Optical Mainframe USB Interface Port on the rear panel to a port on the USB Hub, then connect the control computer USB Interface Port to another port on the USB Hub. The USB Hub is a plug and play device.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system (Probe 1, Probe 2, or Probe 3), see section 2.6.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;[[Image:icon_OBM.png|right|]] Open the [[NeoScan]] Optical Bench Manager program. The [[NeoScan]] Optical Bench Manager program is a Labview-Based System Operation which monitors the system status and the total return and polarization optical powers (see section 3.1 for more details). It is accessible through the desktop or Windows Explorer by double clicking on NeoScanOBM icon [[Image:icon_OBM_small.png]] as shown in Figure 2.7. The program will start running as shown in Figure 2.8.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_7.png|thumb|center|500px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.7&amp;lt;/b&amp;gt;: NeoScan Program Group in or Windows Explorer.&amp;lt;/i&amp;gt;]] &lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
When the program starts, the system should detect the total return power and polarization power and display their graphs over time and show their numerical values in mW, see Figure 2.8. The green “Probe Detected” indicator light will indicate that the probe is connected to the correct channel. Otherwise, if either the total return power or the polarization power is too low (less than 0.3 mW), the information panel will remind the users to correct the problem. This can be the case if the probe is not connected or is defective or there is a problem with the [[NeoScan]] system (Figure 2.9). Select the channel number you want to check using the dropdown list labeled “Select Channel.”&lt;br /&gt;
&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Deploying the Probe on a Probe Fixture ===&lt;br /&gt;
&lt;br /&gt;
During the scan or optimization process, the probe will be mounted on a plastic probe fixtures. The plastic probe fixtures has been mounted on translation stage by a single cap screw and holds the probe (Figure 2.10). The probe is positioned inside the gap located on probe holder and is secured by a cap which is fastened by screws as shown in Figure 2.11.&lt;br /&gt;
 &lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_10.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.10&amp;lt;/b&amp;gt;: Mounting the plastic probe fixtures on a moving translation stage.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Set up the 2-axis translation stage on a stable flat table, an optical table is preferred.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the plastic probe fixtures on the Z linear translation stage using the screw.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Loosen all screws of the cubic probe holder. Lift the cap and rest the probe holder on a flat horizontal flat surface. Gently insert the probe into the gap in the plastic probe holder in such a way that that about 0.6” (1.5cm) of the probe comes out from the either ends of the gap (Figure 2.11).&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;While the probe is sitting inside the gap, place the cap on the probe holder and secure it by fastening the four plastic screws. Make sure it is tight is enough so that the probe does not slip out of the gap. Yet, do not tighten hard since it may break the probe glass. Tighten the screws until you feel that you are not able to rotate the probe by your fingers.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the cube holder inside the probe fixture head in such a way that the probe passes through the existing hole (Figure 2.12). Make sure the probe does not hit the edges of the hole, otherwise, it may break and the crystal may fall off.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;To avoid bending the soft plastic shield of the fiber, pass the fiber through the top of the probe fixture using regular (Scotch) adhesive tapes as shown in Figure 2.13.&amp;lt;/p&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Important: When pulling out the probe from the hole, make sure the probe is positioned vertically and the probe tip does not touch the edges of the hole.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_11.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.11&amp;lt;/b&amp;gt;: Placing the probe inside the probe holder.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Two black markers on the tangential probe indicate the E-field sensitivity direction (probes’ polarization direction). They should be oriented along the electric field in order to detect the maximum signal, see Figure 2.14.&lt;br /&gt;

&lt;div&gt;== Overview ==&lt;br /&gt;
&lt;br /&gt;
Part One&lt;br /&gt;
&lt;br /&gt;
=== General Overview ===&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]]® real-time field measurement and scanning system is a turnkey, electric or magnetic field probe and measurement system. It can be configured as a near-field scanning system for mapping aperture-level field distributions with minimal invasiveness to the device or system under test. Or it can be used as a real-time field probe system for sensing or detecting electric and magnetic fields in a variety of media.&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system can be used as an essential tool for test and evaluation of antennas and phased array systems and is particularly useful for phase characterization and calibration. Unlike conventional near-field scanning systems that utilize metallic radiators to pick up the fields, [[NeoScan]] probes are non-metallic, operating based on electro-optic (EO) or magneto-optic (MO) effects. Its field probes feature extremely small EO or MO crystals mounted at the tip of an optical fiber. The combination of the small probe size and absolutely non-metallic parts leads to the ultimate radio frequency (RF) non-invasiveness.&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]] provides detailed field maps of passive and active devices and circuits including RFIC’s and MMIC’s. Such invaluable information can effectively be used for design validation, model verification, diagnostics and fault isolation or performance evaluation of various parts of RF systems. It is also an alternative compact range for measurement of far-field radiation patterns of antennas and arrays, dispensing with a costly anechoic chamber. The system can be used in real-time, polarimetric and coherent sensing and probing of wideband signals and pulses, EMC/EMI testing, and medical device measurements and characterization of biological environments. The [[NeoScan]] system can be configured in a multi-channel architecture for simultaneous field measurement at multiple points and locations. Different channels can measure different polarizations in a coherent manner.     &lt;br /&gt;

=== General Description ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] real-time field measurement &amp;amp; scanning system provides an entirely new capability for the measurement of high-intensity electric fields. This technology is based on the Pockel’s effect which measures the phase-retardance of an optical beam due to an impinging electric field. This electro-optic effect is observed in non-centrosymmetric crystals when an electric field is directed along certain crystal axes causes a change in the indices of refraction encountered by an incident optical beam. Figure 1.1 shows the basic principle of the electro-optic effect. The electro-optic effect provides a means of modulating the phase or intensity of the optical radiation. In another sense, this effect also makes it possible to detect the presence of an electric field impinging on the crystal. The polarization of an optical beam travelling through a crystal is altered by the electric field in that crystal. The comparison of polarization states allows determination of the amplitude and phase of the existing RF electric field. Since the electro-optic sensing phenomenon relies on small displacements of the atomic crystal structure, the response time of the process is extremely short. This short response time makes it possible to measure high-frequency electric fields up to the terahertz regime.  &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_1_1.png|thumb|center|400px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 1.1&amp;lt;/b&amp;gt;: EO modulation of an optical signal.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A typical EO probe is composed of an optical fiber affixed with an EO crystal coated with a dielectric reflection layer on its bottom surface as shown in Figure 1.2. These probes have very delicate optical interconnects and extreme care must be taken in handling the probes to prevent excessive shock, bending and out of plane stresses.&lt;br /&gt;
&lt;br /&gt;
Due to its broad measurement bandwidth and high spatial resolution, the EO measurement technique is a promising means to characterize RF systems such as microwave and millimeter-wave integrated circuits, HPM sources and systems, and large-scale active arrays and other radiating structures. Unlike the conventional electrical measurement techniques which require some type of metal structure for the resonant detection of an RF signal, [[NeoScan]]’s unique real-time EO electric field measurement method requires no metal components. As a result, the field perturbation caused by introducing metal within the vicinity of a device under test (DUT) is significantly reduced.&lt;br /&gt;
&lt;br /&gt;
Figure 1.3 shows the electric and magnetic fields distribution of a traveling RF wave with a normal probe shown in typical orientation. To detect the maximum electric field in this configuration, the propagation direction of the optical beam of the probe should be parallel to the E-field direction. In general, a normal EO probe is only sensitive to the electric field component parallel to the probe handle, whereas a tangential probe is sensitive to the electric field component perpendicular to the probe handle. Yet, the E-field sensitivity of a tangential probe depends on its crystal orientation sitting on its tip. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;

provide nearly identical performance to a bare probe.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;

The normal probe is oriented with the probe normal to direction of propagation.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
A low noise 1550 nm laser diode is used as optical beam source. The optical connections are fiber-based. The beam is delivered to an optical probe. The polarization of the beam is modulated through an electro-optic crystal on the probe tip. The modulated beam is reflected back into the fiber, and back to the mainframe for analysis. An optical analyzer converts the polarization change of the beam into an amplitude change. The amplitude is linearly proportional to the strength of the external electric field at the probe-crystal location. The equation E=αV is used to calculate the electric field, where α is the calibration factor, or the slope between the electric field E (in V/m) and the measured EO signal V (in V/m/uV). For instance, for a calibration factor of 1.082 V/m/uV. a measured EO signal of 1000 uV (0.001 V), corresponds to and electric field of 1.082 V/m/uV x 1000 V = 1082 V/m.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_1_4.png|thumb|center|480px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 1.4&amp;lt;/b&amp;gt;: An example of a real time measurement of a 6.6 nsec pulse with 10 kV/m peak field strength. The upper trace shown on the oscilloscope is the input signal, and the lower trace is the measured signal.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Due to the fast response of the EO crystal, it is possible to measure extremely high-bandwidth signals with the normal SNR limitations of wideband signal detection. Using this capability, EMAG Technologies Inc. has developed the world’s first fiber-based real-time polarimetric electric field sensor system – [[NeoScan]] – for the measurement of high-power microwave signals. Figure 1.4 is an example of a real time measurement of a 6.6 nsec pulse with 10 kV/m peak field strength. The upper trace shown on the oscilloscope is the received signal, and the lower trace is the detected signal. &lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system is capable of measuring signals with bandwidths up to 20 GHz and signal levels as low as 1 V/m for optical probes with a 10 m PM fiber. Because the optical probes are free of metallic parts, it is possible to measure extremely high-field strengths since there are no free electron surfaces to generate arcing. The [[NeoScan]] can measure fields up at least 2 MV/m and possibly higher.&lt;br /&gt;
&lt;br /&gt;
=== System Overview ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] real-time field measurement and scanning system consists of: &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
An optical mainframe with a touchscreen control computer that can be used for either real-time high power microwave measurement or E-field scanning as shown in Figure 1.5.&lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The power switch on the back will turn the system and the laser on or off. It is recommended to turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. A USB port is used to communicate with control computer. The “Signal Out” channels can be used for real-time measurements. The RF signal can be displayed either on a high resolution oscilloscope or a spectrum analyzer. The channels can also be configured for near-field scanning measurement with a U-jumper SMA Cables. The scanning configuration can measure both amplitude and the phase of the signal with a Lock-in Amplifier. &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;

== NeoScan Probe Installation ==&lt;br /&gt;
&lt;br /&gt;
=== Shipping &amp;amp; Handling Precautions ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] system contains extremely sensitive and fragile components. Use extreme caution whenever operating this system. Do not attempt to service or adjust or install substitute parts to its components. Please contact EMAG Technologies Inc. for service and more information. &lt;br /&gt;
&lt;br /&gt;
In spite of its sophisticated capabilities, the [[NeoScan]] system is easy to learn and operate. You can start using the system within hours. Below are the procedures to help you get started using [[NeoScan]]. We highly recommend that you complete chapters 2 and 3 of [[NeoScan]] and familiarize yourself with its basic functions before attempting to run the system. Turn the [[NeoScan]] system on at least 30 minutes before any operation for warm-up. Before getting started, consider the following precautions:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;The system operates from a 100V or 120V nominal AC power source having a line frequency of 50 or 60 Hz. Before connecting the power cord to a power source, verify that the AC input voltage value is correct.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;[[NeoScan]] real-time field measurement and scanning system contains a 40 mW laser diode emitting Class 3B laser radiation at ~1550 nm. The direct output power from the fiber port of each probe channel on the front panel is less than 10 mW. The beam at 1550 nm is invisible to human being and the invisible beam can be hazardous if directed at the eye. Direct exposure of eye to the invisible laser beam must be avoided.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
&amp;lt;p&amp;gt;The fans in [[NeoScan]] optical mainframe are required to maintain proper operation. Do not block the vents in the frame box.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;In order to avoid EMC/EMI effect, keep the [[NeoScan]] box as far away from the DUT as possible.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt; &lt;br /&gt;
	&amp;lt;p&amp;gt;Follow standard electrostatic-discharge precaution, including grounding yourself prior to making cable connections to the system. A ground strap provides the most effective grounding and minimizes the likelihood of electrostatic damage.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Handle the probes and the PM fibers with extreme care. &amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Gently clean and attach the appropriate fiber connectors to the correct fiber port of the [[NeoScan]] system.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not excessively pull or bend the fiber.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;The probe tip is extremely fragile. Do not strike the probe tip. Always keep the probes in a safe place. &amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Keep the cables and the fibers handy in safe positions, but out of the way and untangled.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Always use an SMA torque wrench when connecting the SMA connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not over-torque the microwave SMA connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Do not over-tighten the optical connectors.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Installing the [[NeoScan]] System ===&lt;br /&gt;
&lt;br /&gt;
[[NeoScan]] optical mainframe is enclosed in a 4U case with dimensions of 24”(H) x 17”(L) x 13” (W) (61cm x 43cm x 33cm). The instrument weighs 60 pounds (27kg) and contains the entire optical system, control systems, and power conditioning circuits required for electric field measurements. It is packaged in foam. Open the cardboard box and remove the layers of foam. Care must be taken to ensure the optical connectors, the SMA connectors, and the USB connectors on the rear panel are not damaged. Remove the fiber port protection caps and keep safe for reuse when repacking the instrument. The instrument box should contain the corresponding power cord, cables and etc. &lt;br /&gt;
&lt;br /&gt;
Unpack the control computer (surface) and the computer holder. Attach the computer holder to the [[NeoScan]] front panel with the screws. Pull up the Holder Lock part on the top left. Place the control computer inside the computer holder. Pull down the Holder Lock part and lock it (Figure 2.1)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== Installing [[NeoScan]] Translation Stage ===&lt;br /&gt;
&lt;br /&gt;
Unpack the [[NeoScan]] translation stage components. To install (see Appendix A-l):&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the Y Linear Translation Stage on a stable flat table, preferably an optical table.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the X Linear Translation Stage on the Y Linear Translation Stage using four screws as shown by red screws in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the Plate on the X Linear Translation Stage. Fasten its four edges with screws as indicated by green arrows in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the X, Y, and Z Miniature Translation Stages on the front edge of the Optical Plate and fasten its four edges with screws as indicated by arrows in Figure 2.2.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Attach the Plastic Probe Fixture to the XYZ Miniature Translation Stage.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_2.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.2&amp;lt;/b&amp;gt;: Installing NeoScan Translation Stage.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Unpacking the EO Probes ===&lt;br /&gt;
&lt;br /&gt;
The [[NeoScan]] probes are extremely sensitive and fragile components. Use extreme caution whenever operating them. EO probes have been packed in separate boxes (Figure 2.3). The probes are delicate, care must be taken to ensure that the fiber and probe tip are not bent hard or dropped. The probe heads are placed in foam and the probes are housed in a box surrounded by bubble wrap on all sides.&lt;br /&gt;
&lt;br /&gt;
To unpack, open the box top. Remove the visible bubble wrap and remove the entire foam structure from the box. Cut the tape holding the foam structure halves together and remove the top. Remove any bubble wrap in the foam structure. Remove the cardboard covering the probe tip and any small pieces of foam holding the EO Probe down in the foam. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
&amp;lt;table&amp;gt;&lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;
&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;td&amp;gt;&lt;br /&gt;

&amp;lt;/td&amp;gt;&lt;br /&gt;
&amp;lt;/tr&amp;gt;&lt;br /&gt;
&amp;lt;/table&amp;gt;&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
To remove a probe and the fiber from the box: &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Carefully press the both sides of the foam near the probe head, carefully un-wedge the probe from its slot, and then lift the probe. Figure 2.4 shows a picture how to remove a probe.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Carefully remove the probe from the foam, making sure to grasp the probe glass tube and not the probe tip, as this may damage the EO probe.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;While holding the probe from its glass tube and keep the fiber sheath in your hand, avoid stretching the white plastic shield part of the fiber. Do not pull the plastic shield part hard.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Handling the Probes and the Fibers ===&lt;br /&gt;
&lt;br /&gt;
The Probes and the fibers are made of a very pure, sensitive, and expensive materials. Treat them with care. Unwind a fiber gently and work out any tangles carefully. &lt;br /&gt;
&lt;br /&gt;
&amp;lt;ul&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT pull hard the fiber.&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT bend the fiber to a radius smaller than 4” (10 cm).&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	DO NOT strike the probe tip. &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ul&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Remove the protective cap on the optical fiber cable connector. Connectors should be cleaned before interconnection. Any dirt or contamination can damage the connector or degrade performance. In other words, fiber optic connectors should to be cleaned every time they are mated and unmated. Use a dry cleaning cloth (reel-based cassette cleaner) to remove dirt, dust, and oil from connector end faces (Figure 2.5). You can also carefully clean a dirty fiber connector with isopropyl alcohol (IPA) and then dry with FIS fiber optic cleaner.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_5.png|thumb|center|600px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.5&amp;lt;/b&amp;gt;: Cleaning a connector end face using a dry cleaning cloth reel-based cassette cleaner.&amp;lt;/i&amp;gt;]] &lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Connecting the Probe to [[NeoScan]] Optical Mainframe ===&lt;br /&gt;
&lt;br /&gt;
The probe is coupled with a 10-meter-long PM fiber and connects to the optical mainframe with a FC/APC optical fiber connector. Remove the APC protection caps and keep safe for reuse when repacking the instrument. Gently clean and attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system. There is a pre-aligned (slow or fast axis) adjustable key connectors for the PM axis alignment across a connection. Make sure the key is aligned in the slot properly before tightening, see Figure 2.6.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;[[Image:neoscanfig_2_6.png|thumb|center|600px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.6&amp;lt;/b&amp;gt;: PM Fiber Optics and Connectors.&amp;lt;/i&amp;gt;]]&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Quick Test of the [[NeoScan]] System ===&lt;br /&gt;
&lt;br /&gt;
As a quick system test:&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Plug in the [[NeoScan]] optical mainframe power cord into an electrical receptacle and turn it on.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect control computer AC power adapter and turn on the control computer.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect USB multi-port Hub AC power adapter to the power.&amp;lt;/p&amp;gt; &lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Connect the [[NeoScan]] Optical Mainframe USB Interface Port on the rear panel to a port on the USB Hub, then connect the control computer USB Interface Port to another port on the USB Hub. The USB Hub is a plug and play device.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Attach the appropriate fiber connectors to the correct fiber ports of the [[NeoScan]] system (Probe 1, Probe 2, or Probe 3), see section 2.6.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;[[Image:icon_OBM.png|right|]] Open the [[NeoScan]] Optical Bench Manager program. The [[NeoScan]] Optical Bench Manager program is a Labview-Based System Operation which monitors the system status and the total return and polarization optical powers (see section 3.1 for more details). It is accessible through the desktop or Windows Explorer by double clicking on NeoScanOBM icon [[Image:icon_OBM_small.png]] as shown in Figure 2.7. The program will start running as shown in Figure 2.8.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_7.png|thumb|center|500px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.7&amp;lt;/b&amp;gt;: NeoScan Program Group in or Windows Explorer.&amp;lt;/i&amp;gt;]] &lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
When the program starts, the system should detect the total return power and polarization power and display their graphs over time and show their numerical values in mW, see Figure 2.8. The green “Probe Detected” indicator light will indicate that the probe is connected to the correct channel. Otherwise, if either the total return power or the polarization power is too low (less than 0.3 mW), the information panel will remind the users to correct the problem. This can be the case if the probe is not connected or is defective or there is a problem with the [[NeoScan]] system (Figure 2.9). Select the channel number you want to check using the dropdown list labeled “Select Channel.”&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== Deploying the Probe on a Probe Fixture ===&lt;br /&gt;
&lt;br /&gt;
During the scan or optimization process, the probe will be mounted on a plastic probe fixtures. The plastic probe fixtures has been mounted on translation stage by a single cap screw and holds the probe (Figure 2.10). The probe is positioned inside the gap located on probe holder and is secured by a cap which is fastened by screws as shown in Figure 2.11.&lt;br /&gt;
 &lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_10.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.10&amp;lt;/b&amp;gt;: Mounting the plastic probe fixtures on a moving translation stage.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;ol&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Set up the 2-axis translation stage on a stable flat table, an optical table is preferred.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Mount the plastic probe fixtures on the Z linear translation stage using the screw.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Loosen all screws of the cubic probe holder. Lift the cap and rest the probe holder on a flat horizontal flat surface. Gently insert the probe into the gap in the plastic probe holder in such a way that that about 0.6” (1.5cm) of the probe comes out from the either ends of the gap (Figure 2.11).&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;While the probe is sitting inside the gap, place the cap on the probe holder and secure it by fastening the four plastic screws. Make sure it is tight is enough so that the probe does not slip out of the gap. Yet, do not tighten hard since it may break the probe glass. Tighten the screws until you feel that you are not able to rotate the probe by your fingers.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Place the cube holder inside the probe fixture head in such a way that the probe passes through the existing hole (Figure 2.12). Make sure the probe does not hit the edges of the hole, otherwise, it may break and the crystal may fall off.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;li&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;To avoid bending the soft plastic shield of the fiber, pass the fiber through the top of the probe fixture using regular (Scotch) adhesive tapes as shown in Figure 2.13.&amp;lt;/p&amp;gt;&lt;br /&gt;
	&amp;lt;p&amp;gt;Important: When pulling out the probe from the hole, make sure the probe is positioned vertically and the probe tip does not touch the edges of the hole.&amp;lt;/p&amp;gt;&lt;br /&gt;
&amp;lt;/li&amp;gt;&lt;br /&gt;
&amp;lt;/ol&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;center&amp;gt;&lt;br /&gt;
[[Image:neoscanfig_2_11.png|thumb|center|650px|&amp;lt;i&amp;gt;&amp;lt;b&amp;gt;Figure 2.11&amp;lt;/b&amp;gt;: Placing the probe inside the probe holder.&amp;lt;/i&amp;gt;]]&lt;br /&gt;
&amp;lt;br&amp;gt;&lt;br /&gt;

&amp;lt;/center&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Two black markers on the tangential probe indicate the E-field sensitivity direction (probes’ polarization direction). They should be oriented along the electric field in order to detect the maximum signal, see Figure 2.14.&lt;br /&gt;
&lt;br /&gt;

What formulae are used while calculating the radiation patterns, and other parameters like gain, directivity&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
what is meant by LCS settings?&lt;br /&gt;
&lt;br /&gt;
[[EM.Cube]] provides a number of different coordinate systems. The two most important ones are the World Coordinate System (WCS) and the Local Coordinate System (LCS). Every object has a Local Coordinate System that determines the location of the object in the world coordinate system and its orientation, i.e., its rotation angles with respect to the world principal axes. The center of the local coordinate system is the most important characteristic point of an object. The position of the LCS center varies among different object types. For example, the LCS center of a box is the center of its bottom face, while the LCS center of a sphere is its true geometrical center. The LCS has three local X-, Y-, and Z-axes. For most objects, these axes line up with the object's natural axes. For example, the local Z-axis of a cylinder or a cone is always aligned along its geometrical axis. For further information please see the &amp;quot;Local Coordinate System&amp;quot; section at:&lt;br /&gt;

&lt;br /&gt;
How can we include different materials/metals and their properties in predefined arrays?&lt;br /&gt;
 &lt;br /&gt;
For simplicity, in our tutorials we use wizards to create antenna for a project. However, one can starts project from scratch and include different materials/metals with their properties in their design and then use the &amp;quot;Array Tool&amp;quot; from the tool bar to create an array. We may not need to use wizards for a complicated design.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
How do we change the element spacing in line arrays? &lt;br /&gt;
 &lt;br /&gt;
If you start your project from scratch and use &amp;quot;Array Tool&amp;quot; to create say a 3 x 3 array with 5 mm spacing, simply set Element Count for X, Y and Z to 3, 3 and 1 respectively, and Spacing to 5, 5, and 0 for X, Y, and Z respectively, in Array Properties dialog window as indicated in the attached figure. &lt;br /&gt;
 &lt;br /&gt;
However, if you use a wizard, the Spacing might be parameterized in terms of other variables. For instance, in [[EM.Libera]]'s Tutorial Lesson 2, In in Array Properties dialog window the Element Count for X, is expressed as direct_spacing_lambda and X Spacing is defined in terms of n_direct. To change X Element Count = 50 and X Spacing = 7 you may simply replace  n_direct with 7 and direct_spacing_lambda with 50.&lt;br /&gt;
&lt;br /&gt;
Alternatively, it is suggested, to keep n_direct and direct_spacing_lambda in the Array Properties dialog window untouched, yet, change their values from the Variables dialog window.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
What is a good way to draw a surface with a curve of y0 * exp(r*x) where I can run a parametric study of r?  Again drawing parametric curves and then fill fixed the design.  &lt;br /&gt;

I have been using EMCUBE on my new workstation. I just realized that the wizards (e.g., the wire dipole wizard) are not active. If I remember correctly, I faced this issue previously and it was because one of the folders were missing (the folder with the python based wizards I think). I don't have that folder anymore. &lt;br /&gt;
&lt;br /&gt;
. There are few updates that were not included in the link EMCUBEfiles.zip we sent you on February. Therefore, we include them in EMCubeNewWiz.zip file that can download it from the following link:&lt;br /&gt;
&lt;br /&gt;
http://www.emagtech.com/downloads/EMCubeNewWiz.zip&lt;br /&gt;
&lt;br /&gt;
1.	Please Unzip EMCubeNewWiz.zip file. It contains three folders Models, Python, and Wizards. &lt;br /&gt;
2.	Copy or move the new Models, Python, and Wizards into C:\Users\username\Documents\EMAG folder let it overwrite the existing ones.&lt;br /&gt;
&lt;br /&gt;
Kaz has mentioned that you have problem with plot function while trying to plot for the second time. You cannot have more than one PyPlot graph window open at one time. For this reason an error window pops up indicating &amp;quot;Another PyPlot window ... is already open. Please close ...&amp;quot;  In other words, you have to close the 1st PyPlot graph window before plotting another graph or running the simulation. &lt;br /&gt;
&lt;br /&gt;
Nonetheless, sometimes the PyPlot window will buried or concealed under other windows. Please make sure to bring the PyPlot window up/front and close it before plotting another data set.&lt;br /&gt;
&lt;br /&gt;
The advantage of using PyPlot is that allows you to plot two data set files (with same type, e.g. .CPX) in the same PyPlot graph window as shown in the attached figure. You can have two instances of [[EM.Cube]] program and each have independent PyPlot graph windows.&lt;br /&gt;

I read from your website that your software can determine k-beta diagram of periodic structures which is commonly called DISPERSION DIAGRAM. Do you have any model for that purpose? I searched periodic structures and could not find any model.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
To determine k-beta diagram of periodic structures, you can follow our [[EM.Tempo Tutorial Lesson 8: Analyzing A Periodic Frequency Selective Surface]]:&lt;br /&gt;
&lt;br /&gt;
http://www.emagtech.com/wiki/index.php/EM.Tempo_Tutorial_Lesson_8:_Analyzing_A_Periodic_Frequency_Selective_Surface&lt;br /&gt;

&lt;br /&gt;
How can I  import my own radiation patterns in Terrano *.rad where I have for each antenna in the transmitter and receiver both the co-polarized and cross-polarized radiation patterns?  Also, do you have the manual of Terrano?&lt;br /&gt;
&lt;br /&gt;
. To import a radiation patterns (*.rad) in [[EM.Terrano]] open the property dialog of the transmitter set (or receiver set) and select the radio button labeled User Defined Antenna Pattern as the radiator type. Then click the Import button of the dialog. The Windows standard Open dialog opens up with the file type set to &amp;quot;.RAD&amp;quot;. Browse your folders to find the downloaded pattern file. Select it and click the Open button. You will see the path of the downloaded file in the box next to the Import button. &lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
1. Picasso: Is it possible to define Vias that go through more than one layer ?&lt;br /&gt;
&lt;br /&gt;
You can define Vias' for each layer in such a way that they are positioned/located on top of one another and are exactly the same.&lt;br /&gt;
&lt;br /&gt;
2. Why loss tangent is not automatically specified for known commercial materials, e.g. RO4003C ?&lt;br /&gt;
&lt;br /&gt;
Thank you for bringing it into our attention. We will add it in the next released version.&lt;br /&gt;
&lt;br /&gt;
3. Is it possible to Copy and object together with rotation/mirror ?&lt;br /&gt;
&lt;br /&gt;
Mirror operation keeps the original object and create a new one. Yet, in rotation the original object will change. For this reason you may copy and the rotate the copied object.&lt;br /&gt;
&lt;br /&gt;
4. Can [[EM.Cube|EM-cube]] support metal surface roughness (this is crucial for high microwave applications) ?&lt;br /&gt;
&lt;br /&gt;
We do not have a parameter for the surface roughness in [[EM.Picasso]]. However, there is a relation between the surface roughness and the effective conductivity. You can use &amp;quot;Conductive Sheet Traces&amp;quot; with the effective conductivity. and rms height  instead of &amp;quot;PEC Traces&amp;quot;. We will add this option in the next release.&lt;br /&gt;
&lt;br /&gt;
1) How do I write the Python Code for my own objects and add it to the simulation? Is it possible to access some part of the code for reference?&lt;br /&gt;
&lt;br /&gt;
The following link provide an example how to write a Python script &lt;br /&gt;
&lt;br /&gt;
http://www.emagtech.com/wiki/index.php/EM.Tempo_Tutorial_Lesson_7:_Designing_A_Pyramidal_Horn_Antenna#Writing_a_Python_Script_for_Calculation_of_Pyramidal_Horn_Directivity&lt;br /&gt;
&lt;br /&gt;
Here is a more detailed information on [[Using Python to Create Functions, Models &amp;amp; Scripts]]&lt;br /&gt;
&lt;br /&gt;
http://www.emagtech.com/wiki/index.php/Using_Python_to_Create_Functions,_Models_%26_Scripts&lt;br /&gt;
&lt;br /&gt;
2) For modelling of wired antennas, I have used thin wires for respective elements. How will I consider the geometry of a thin wire for calculating current densities in each element? Also, do I have to take only thin wires or while modelling wired antennas or will cylindrical structures do? &lt;br /&gt;
&lt;br /&gt;
In [[EM.Libera]], if you open up he Thin Wire dialog, in the property dialog, you can change the define the wire radius from &amp;quot;Wire Radius&amp;quot; box. In other words, it’s a tiny cylinder with small radius of &amp;quot;Wire Radius.&amp;quot; &lt;br /&gt;
&lt;br /&gt;
Please see &amp;quot;Constructing the Wire Dipole Antenna Geometry&amp;quot; section in the [[EM.Libera Tutorial Lesson 1: Analyzing A Center-Fed Wire Dipole Antenna]]&lt;br /&gt;
&lt;br /&gt;
http://www.emagtech.com/wiki/index.php/EM.Libera_Tutorial_Lesson_1:_Analyzing_A_Center-Fed_Wire_Dipole_Antenna#Constructing_the_Wire_Dipole_Antenna_Geometry&lt;br /&gt;
&lt;br /&gt;
3) What exactly is the function of a 'Port Definition'? How is it used in calculating the antenna parameters?&lt;br /&gt;
&lt;br /&gt;
Ports are defined to calculate the scattering, impedance and admittance parameters of a one-port or multiport structure. &lt;br /&gt;
&lt;br /&gt;
Port Definition Observable&lt;br /&gt;
&lt;br /&gt;
http://www.emagtech.com/wiki/index.php/Glossary_of_EM.Cube%27s_Simulation_Observables_%26_Graph_Types#Port_Definition_Observable&lt;br /&gt;
&lt;br /&gt;
Graphing Port Characteristics &amp;amp; Other Complex-Valued Data&lt;br /&gt;

http://www.emagtech.com/wiki/index.php/Defining_Project_Observables_%26_Visualizing_Output_Data#Graphing_Port_Characteristics_.26_Other_Complex-Valued_Data&lt;br /&gt;
&lt;br /&gt;
4) How do I use the 'Wire gap circuit source' in between two thin wires? If it is not possible, is there any other method of excitation? &lt;br /&gt;
&lt;br /&gt;
A wire gap source must always be associated with an existing line object in the project workspace. Please note that when you define your line object say 150 mm, the wire gap source  creates an infinitesimal gap on the line, i.e. create two lines of 75 mm length, and connects a voltage source across the gap. All happens behind the scene. Please look at Examining the Gap Source &amp;amp; Simulation Observables in Lesson 1&lt;br /&gt;
&lt;br /&gt;
http://www.emagtech.com/wiki/index.php/EM.Libera_Tutorial_Lesson_1:_Analyzing_A_Center-Fed_Wire_Dipole_Antenna#Examining_the_Gap_Source_.26_Simulation_Observables&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
1. How do i set simultaneous excitation of multiple ports ?&lt;br /&gt;
2. Can i use amplitude of -1 in order to create a 180 phase shift between ports in the FDTD simulation ? &lt;br /&gt;
    otherwise, how can i stimulate 2 ports with 180 degrees phase shift ?&lt;br /&gt;
3. Can i choose some ports to be stimulated and others with no stimulation (just as a termination) ?&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
You can define multiple sources that will set the corresponding ports.  In [[EM.Cube]] amplitude of the source should not be negative. For this reason, in order to introduce phase shift of 180 deg., you can click on &amp;quot;Waveform...&amp;quot; button in the &amp;quot;Source Properties&amp;quot; section of a Source dialog window. In the &amp;quot;Excitation Waveform&amp;quot; dialog window, set the Amplitude to 1 and the Phase to 180. Similarly, by setting the Amplitudes of some sources to 0 (zero) you can let some ports to be stimulated while those with zero amplitude without any stimulation (terminated).&lt;br /&gt;
&lt;br /&gt;
To calculate S11-S12, you can do post-processing by getting them into Python. You can perform some operations (add, subtraction ...) on RCSs, Radiation Patterns, Field Sensors, etc. Yet, we do not have any Python function for S-parameter operations. We will implement some new Python in the next [[EM.Cube]] release.&lt;/div&gt;</summary>
