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 typical use of these transistors is as a switch for moderate voltages and currents, including as drivers for small lamps, motors, and relays. [1] In switching circuits, these FETs can be used much like bipolar junction transistors , but have some advantages:
BSIM (Berkeley Short-channel IGFET Model) [1] refers to a family of MOSFET transistor models for integrated circuit design. It also refers to the BSIM group located in the Department of Electrical Engineering and Computer Sciences (EECS) at the University of California, Berkeley, that develops these models.
For NPN open collector outputs, the emitter of the NPN transistor is internally connected to ground, [1] so the NPN open collector internally forms either a short-circuit (technically low impedance or "low-Z") connection to the low voltage (which could be ground) when the transistor is switched on, or an open-circuit (technically high impedance ...
If all the input voltages are low (logical "0"), the transistor is cut-off. The pull-down resistor R 1 biases the transistor to the appropriate on-off threshold. The output is inverted since the collector-emitter voltage of transistor Q 1 is taken as output, and is high when the inputs are low. Thus, the analog resistive network and the analog ...
The 2N3904 is an NPN transistor that can only switch one-third the current of the 2N2222 but has otherwise similar characteristics. The 2N3904 exhibits its forward gain (beta) peak at a lower current than the 2N2222, and is useful in amplifier applications with reduced I c, e.g., (gain peak at 10 mA for the 2N3904 but 150 mA for the 2N2222).

The assignment of transistor elements (b, c, e) to leads, i.e. the "pinout", uses the same convention used by some - but not all - other TO-92 devices. As viewed in the top-right image, going from left to right, the pinout is as follows: lead 1 (left in diagram) is the collector, lead 2 is the base, and; lead 3 is the emitter. [8]
