field-effect transistor

n

(Electronics) a unipolar transistor consisting of three or more electrode regions, the source, one or more gates, and the drain. A current flowing in a channel between the highly doped source and drain is controlled by the electric field arising from a voltage applied between source and gate Abbreviation FET See also JFET, IGFET
