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.
Figure 1: Basic NPN common collector circuit (neglecting biasing details).. In electronics, a common collector amplifier (also known as an emitter follower) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a voltage buffer.
The MOSFET is by far the most widely used transistor for both digital circuits as well as analog circuits, [104] accounting for 99.9% of all transistors in the world. [102] The bipolar junction transistor (BJT) was previously the most commonly used transistor during the 1950s to 1960s.
Ambarella Inc. announced the availability of the A7L system-on-a-chip circuit for digital still cameras, providing 1080p60 high-definition video ... transistors in ...
Full hybrid-pi model. The full model introduces the virtual terminal, B′, so that the base spreading resistance, r bb, (the bulk resistance between the base contact and the active region of the base under the emitter) and r b′e (representing the base current required to make up for recombination of minority carriers in the base region) can be represented separately.
It is applicable to electronic circuits in which the AC signals (i.e., the time-varying currents and voltages in the circuit) are small relative to the DC bias currents and voltages. A small-signal model is an AC equivalent circuit in which the nonlinear circuit elements are replaced by linear elements whose values are given by the first-order ...
The intersections of the load line with the transistor characteristic curves represent the circuit-constrained values of I C and V CE at different base currents. [2] If the transistor could pass all the current available, with no voltage dropped across it, the collector current would be the supply voltage V CC over R L. This is the point where ...
