  • acronym formetal oxide semiconductor field effect transistor


  • Acronym for metal-oxide semiconductor field effect transistor. A field-effect transistor whose gate is insulated from the channel by a thin layer consisting of a metal oxide, such as silicon dioxide. MOSFETs feature extremely high input impedance and low power consumption, and are used, for instance, in high-gain audio amplifier circuits, and for computer memory. It is a type of IGFET, and both terms are usually utilized synonymously, but MOSFET is a much more common term. Also called MOS transistor.
