List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE.The following table is split into two groups based on whether it has a graphical visual interface or not.
If the MOSFET is an n-channel or nMOS FET, then the source and drain are n+ regions and the body is a p region. If the MOSFET is a p-channel or pMOS FET, then the source and drain are p+ regions and the body is a n region. The source is so named because it is the source of the charge carriers (electrons for n-channel, holes for p-channel) that ...
It offers the ability to set up a circuit with a graphical user interface and simulate the large-signal, small-signal and noise behaviour of the circuit. Originally, Qucs was composed of a circuit simulator "qucs-core", now Qucsator, and a GUI for schematic entry and plotting. The usage patterns, as well as the emphasis on RF design, were ...
NL5 DLL is an NL5 transient simulation engine with an API in the form of a Windows DLL. It can be used as an analog simulation engine for co-simulation with System Verilog digital simulators (e.g. Xilinx Vivado). Also, NL5 DLL functions can be called from C/C++ applications, MATLAB, Python, etc., and perform co-simulation with user's tool of ...
Native silicon has a lower conductivity than silicon in an n-well or p-well, as most MOSFETs are, and therefore must be larger to achieve equivalent conductance. Typical minimal size of the native N-channel MOSFET (NMOS) gate is 2-3 times longer and wider than standard threshold voltage transistor. The cost of chips including native transistors ...
It is fully interactive and command driven. It can also be run in batch mode or as a server. The output is produced as it simulates. With grant funding from Nlnet, [5] the Gnucap project started to implement a first free/libre simulator with Verilog-AMS capabilities. As of July 2023 the model generator covers most of the analog subset and ...
PSIM is an Electronic circuit simulation software package, designed specifically for use in power electronics and motor drive simulations but can be used to simulate any electronic circuit. Developed by Powersim, PSIM uses nodal analysis and the trapezoidal rule integration [2] as the basis of its simulation algorithm. PSIM provides a schematic ...
A MOSFET can be made to operate as a resistor, so the whole circuit can be made with n-channel MOSFETs only. NMOS circuits are slow to transition from low to high. When transitioning from high to low, the transistors provide low resistance, and the capacitive charge at the output drains away very quickly (similar to discharging a capacitor ...
