  2. Diode modelling - Wikipedia

    en.wikipedia.org/wiki/Diode_modelling

    Shown for reference is the standard Shockley-diode model (marked by blue-diamonds). The Shockley parameters are I s = 1e - 12 A, V t = 0.0258 V. When more accuracy is desired in modelling the diode's turn-on characteristic, the model can be enhanced by doubling-up the standard PWL-model.

  3. Semiconductor device modeling - Wikipedia

    en.wikipedia.org/wiki/Semiconductor_device_modeling

    Semiconductor device modeling creates models for the behavior of the electrical devices based on fundamental physics, such as the doping profiles of the devices. It may also include the creation of compact models (such as the well known SPICE transistor models), which try to capture the electrical behavior of such devices but do not generally ...

  4. Spectre Circuit Simulator - Wikipedia

    en.wikipedia.org/wiki/Spectre_Circuit_Simulator

    Spectre is a SPICE-class circuit simulator owned and distributed by the software company Cadence Design Systems.It provides the basic SPICE analyses and component models. It also supports the Verilog-A modeling langua

  5. Gummel–Poon model - Wikipedia

    en.wikipedia.org/wiki/Gummel–Poon_model

    The Gummel–Poon model and modern variants of it are widely used in popular circuit simulators such as SPICE. A significant effect that the Gummel–Poon model accounts for is the variation of the transistor β F {\displaystyle \beta _{\text{F}}} and β R {\displaystyle \beta _{\text{R}}} values with the direct current level.

  6. LTspice - Wikipedia

    en.wikipedia.org/wiki/LTspice

    The text that describes intrinsic SPICE models can be placed directly on an LTspice schematic by using the spice directive .op button. [18] The advantage of this method is the 3rd party model is self-contained as part of the schematic when you distribute the schematic file.

  7. Ngspice - Wikipedia

    en.wikipedia.org/wiki/Ngspice

    SPICE [5] is the origin of most modern electronic circuit simulators, its successors are widely used in the electronics community. Xspice [6] is an extension to Spice3 that provides additional C language code models to support analog behavioral modeling and co-simulation of digital components through a fast event-driven algorithm.

    To simulate the filter at 1GHz, or any frequency, the element Y parameters must be converted to numerical entries using Y parameter models appropriate for the element installed. For ideal inductors and capacitors, the well known Y11 = Y22 = -Y12 = -Y21 = j 2 π f L {\displaystyle j2\pi fL} for inductors and Y11 = Y22 = -Y12 = -Y21 = − j / ( 2 ...
