npn

Example:In early radio tuners, npn bipolar transistors were used for signal amplification.

Definition:A transistor with three terminals where the current in one terminal controls the current in another by the effect of an applied voltage to the third.

Example:BJTs with npn structures are common in amplification circuits.

Definition:A type of transistor that uses the flow of charged particles through a base region to control the flow between the emitter and collector.
