Field Effect Transistor

Field-effect transistors (FETs) are integral to electronic circuits and distinguished by their three-terminal setup: the gate, drain, and source. These transistors operate as unipolar devices, which utilize either electrons or holes as charge carriers, in contrast to bipolar transistors, which use both types of carriers. The primary function of ...

A field effect transistor is a three-terminal unipolar device comprising a gate, drain, and source terminal.

Charge carriers flow from the source to the drain through a channel, the conductivity of which is controlled by the potential difference applied between the gate and the source terminal.

Based on the structure of the gate di...
