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
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. This model uses two piecewise-linear diodes in parallel, as a way to model a single diode more accurately. PWL Diode model with 2 branches. The top branch has a lower forward-voltage and a higher ...
1N4001 diode in DO-41 axial package (through hole mount) A schematic symbol for general-purpose silicon rectifier diodes Current-voltage characteristics of a 1N4001 at different temperatures The 1N400x (or 1N4001 or 1N4000 [ 1 ] ) series is a family of popular one- ampere general-purpose silicon rectifier diodes commonly used in AC adapters for ...
LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). [2] It is the most widely distributed and used SPICE software in the industry. [6]
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.
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 ...
For example, elements can use real or integer values to simulate DSP functions or sampled data filters. Because the event-driven algorithm is faster than the standard SPICE matrix solution, simulation time is greatly reduced for circuits that use event-driven models in place of analog models. [5]
SmartSpice is a commercial version of SPICE (Simulation Program with Integrated Circuit Emphasis) developed by Silvaco.SmartSpice is used to design complex analog circuits, analyze critical nets, characterize cell libraries, and verify analog mixed-signal designs.
