Forward current gain

The "gain" of a bipolar transistor normally refers to forward current transfer ratio, either hFE ("beta", the static ratio of Ic divided by Ib at some operating point), or sometimes hfe (the small-signal current gain, the slope of the graph of Ic against Ib at a point). See more In electronics, gain is a measure of the ability of a two-port circuit (often an amplifier) to increase the power or amplitude of a signal from the input to the output port by adding energy converted from some power supply to the signal. It is … See more Power gain Power gain, in decibels (dB), is defined as follows: See more • Active laser medium • Antenna gain • Aperture-to-medium coupling loss • Automatic gain control • Attenuation See more WebJan 2, 2024 · A bipolar NPN transistor has a DC current gain, ( Beta) value of 200.
