Drain current 0 If ACMAG is omitted following the keyword AC, a value of unity is assumed. - 0 0 Parameter Noise parameter B Description Charge storage effects are modeled by a transit time, TT, and a nonlinear depletion layer capacitance which is determined by the parameters CJO, VJ, and M. CLC B1 A. Klönne Hochschule Karlsruhe – Technik und Wirtschaft 2 Spice-Modell als Subcircuit einbinden Alternativ kann unter Nutzung des bereits bestehenden Transistorsymbols ein Subcircuit erstellt werden, mit dem das neue Modell aufgerufen wird. If ACPHASE is omitted, a value of zero is assumed. LL All these parameters are used by SPICE to describe the behavior of the diode in the different situations of signal, for example in direct polarization in DC that, forward current will be: ID = IS* (e^ (VD/ (N*Vt))-1) where VD is the forward voltage, Vt = k * T / q is the thermal voltage equal … n+ is the positive node, and n- is the negative node. m/V 1E-4 The direction of positive controlling current flow is from the positive node, through the source, to the negative node.   m Body effect coefficient of RDSW Second non saturation factor Jname nD nG nS Mname . Width offset from Weff for RDS calculation var next=new Array("down", "dsbl", "out", "over", "up"); - V 2E-6 UB1 Noise parameter A V/K To attempt standardization of these models so that a set of model parameters may be used in different simulators, an industry working group was formed, the Compact Model Council , [33] to choose, maintain and promote the use of standard models. TOX bulk sheet resistance 0 Contributors of LTwiki will replace this text with their entries.) MJSW Nodes n+ and n- are the nodes between which the switch terminals are connected. Drain-Source to channel coupling capacitance m The series is a set of tutorials and information on SPICE simulation, OrCAD pSPICE compatibility, SPICE modeling, and other concepts in circuit simulation. next["over"] = "wwhgifs/nextover.gif"; 1.7E17 The following two groups are used to model the AC and noise behavior of the MOS transistor. distance drain to bulk contact F/m 1 0.33 Second-order mobility degradation coefficient 5E4 / 2.4E3 Value is the voltage gain.

CJSWG DVT0W A0 NCH Body-effect far from interface Value F/m2 The values of the V and I parameters determine the voltages and currents across and through the device, respectively. WWL PARAM User defined parameters. The switch is not quite ideal, in that the resistance can not change from 0 to infinity, but must always have a finite positive value. PVAG 0.0 - LEVEL The .MODEL statement defines simple components such as diodes, transistors, MOSFETs etc with a list of predefined characteristics given to us by the writers of SPICE programs. Default Value Temperature coefficient for CJSW 2.4E-4 0 Value is the resistance (in ohms) and may be positive or negative but not zero. NOIA Gate-source overlap capacitance per unit W m 0 XJ 1/V A fallback strategy is to build a SPICE model from those parameters listed on the data sheet. A current source of positive value forces current to flow out of the n+ node, through the source, and into the n- node. WINT Temperature coefficient for UA 0 If the source value is zero both for dc and transient analyses, this value may be omitted. Light doped source-gate region overlap capacitance prev["down"] = "wwhgifs/prevdown.gif"; Default Value Circuit simulation is an important part of any design process. 0 0 -7.61E-18 -4.65E-11 next["dsbl"] = "wwhgifs/nextdsbl.gif"; Then, calculate, compare and adjust the SPICE parameters to the measurements. (m/V)2 SPICE Model Parameters for Transistors Accuracy Optimization. L and W are the channel length and width, in meters. - Value is the inductance in Henries. Value is the capacitance in Farads. 2 cm/s If left unspecified, the default SPICE parameter values will be used. For more information, see the SPICE Simulation Fundamentals main page. 1/V Threshold voltage temperature coefficient Return to LTspice Annotated and Expanded Help* Commentary, Explanations and Examples (This section is currently blank. 3.0 0 If I is given then the device is a current source, and if V is given the device is a voltage source. Note that a lossy transmission line with zero loss may be more accurate than than the lossless transmission line due to implementation details. Provides support for Ethernet, GPIB, serial, USB, and other types of instruments. PSPICE: starting a project, adding parts to a circuit, wiring a circuit together, using probes, and setting up an using a simulation profile.!!

Ideal threshold voltage The series is a set of tutorials and information on SPICE simulation, OrCAD pSPICE compatibility, SPICE modeling, and other concepts in circuit simulation. Setting the Gain The simplest Op Amp model is a Voltage-Controlled-Voltage-Source (VCVS) (see my article MasteringElectronicsDesign.com:An Ideal Operational Amplifier Simulation Model ). Charge partitioning coefficient 0 VALUE is the transconductance (in mhos). Poly gate doping concentration Parameter 6 Temperature coefficient for PB Save the model and close model editor. First non saturation factor 5.0E-10 2.2 - AF Table below lists the model parameters for some selected diodes. Bulk charge effect coefficient KT1 Length offset fitting parameter from C-V This means that the model will mimic the op amp functionality, but will not have any transistor or any other semiconductor SPICE models.
