WebSep 22, 2024 · A Field Effect Transistor (FET) is a three-terminal Active semiconductor device, where the output current is controlled by an electric field generated by the input voltage. FETs are also known as unipolar transistors because, unlike bipolar transistors, FETs only have either electrons or holes operating as charge carriers. WebFETs ( JFETs or MOSFETs) are devices with three terminals: source, gate, and drain. FETs control the flow of current by the application of a voltage to the gate, which in turn alters the conductivity between the drain and …
