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 usually defined as the mean ratio of the signal amplitude or power at the output port to the amplitude or power at the input port. It is often expressed using the WebApr 10, 2024 · Published on Apr. 10, 2024. Image: Shutterstock / Built In. A field-effect transistor (FET) is a type of transistor that uses an electric field to control the current flow through a semiconductor channel. FETs are widely used in electronic circuits due to their high input impedance, low output impedance and high gain.
