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.
A modified version of the cascode can also be used as a modulator, particularly for amplitude modulation. The upper device supplies the audio signal, and the lower is the RF amplifier device. High-voltage stack. A cascode may also be combined with a voltage ladder to form a high-voltage transistor.
TINA 9.0 also includes microcontroller (MCU) simulation, RF network analysis, optimization, and printed circuit board design. [2] TINA development was at version 10, released in 2013, and is at major version 11 since 2016. [4] Since 2004, TINA-TI is a free limited version for the support of integrated circuits and applications licensed by Texas ...
Cascode Voltage Switch Logic (CVSL) refers to a CMOS-type logic family which is designed for certain advantages. It requires mainly N-channel MOSFET transistors to implement the logic using true and complementary input signals, and also needs two P-channel transistors at the top to pull one of the outputs high.
A transconductance amplifier (g m amplifier) puts out a current proportional to its input voltage. In network analysis, the transconductance amplifier is defined as a voltage controlled current source (VCCS). These amplifiers are commonly seen installed in a cascode configuration, which improves the frequency response.
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 ...
Process variations occur when the design is fabricated and circuit simulators often do not take these variations into account. These variations can be small, but taken together, they can change the output of a chip significantly. Temperature variation can also be modeled to simulate the circuit's performance through temperature ranges. [8]
Figure 1: Basic N-channel JFET common-source circuit (neglecting biasing details). Figure 2: Basic N-channel JFET common-source circuit with source degeneration. In electronics, a common-source amplifier is one of three basic single-stage field-effect transistor (FET) amplifier topologies, typically used as a voltage or transconductance amplifier.
