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 ]
Schematic of Spice Gummel–Poon model NPN. The Gummel–Poon model is a model of the bipolar junction transistor.It was first described in an article published by Hermann Gummel and H. C. Poon at Bell Labs in 1970.
A solution of this equation is below, and two boundary conditions are used to solve and find and . = + The following equations apply to the ...
LTspice software Mike Thomas Engelhardt [ 1 ] is an American computer programmer , author, and entrepreneur. [ 2 ] He is renowned for developing the SPICE -based analog electronic circuit simulator computer software known as LTspice [ 3 ] and QSPICE .
The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.
The output voltage can be determined from the equation V out = V DC · R DS / (R 1 + R DS). An LTSpice simulation of the non-linearized VCR design verifies that the JFET resistance changes with a change in gate-to-source voltage (V GS). In the simulation (below), a constant input voltage is applied (the VDC supply is set to 4 volts), and the ...
The Shockley diode equation relates the diode current of a p-n junction diode to the diode voltage .This relationship is the diode I-V characteristic: = (), where is the saturation current or scale current of the diode (the magnitude of the current that flows for negative in excess of a few , typically 10 −12 A).
CircuitLogix electronics simulation software.. Electronic circuit simulation uses mathematical models to replicate the behavior of an actual electronic device or circuit. . Simulation software allows for the modeling of circuit operation and is an invaluable analy
