field-effect transistor

noun Electronics.

1. a transistor in which the output current is varied by varying the value of an electric field within a region of the device. Abbreviation: FET

noun

1. 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 gateAbbreviation: FET See also JFET, IGFET
