Description
A Bipolar Junction Transistor is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
- Two types of BJTs, the NPN and PNP
- The two junctions are termed the base-emitter junction and the base-collector junction
- In order for the transistor to operate properly, the two junctions must have the correct dc bias voltage
- – the base-emitter (BE) junction is forward biased
- – the base-collector (BC) junction is reverse biased
