bipolarjunction transistor - (BJT), A three terminal device in which emitter to collector current is controlled by base current. complementry transistors - Two transistors, one NPN and one PNP having near identical charastics. N-channel and P-channel FETs can also be complementry. field effect transistor - (FET) A voltage controlled transistor in which the source to drain conduction is controlled by gate to source voltage. metal oxide field effect transistor - (MOSFET) A field effect transistor in which the insulating layer betwen the gate electrode and the channel is a metal oxide layer. npn transistor - A bipolar junction transistor in which a p-type base element is sandwiched between an n-type emitter and an n-type collector.
