A bipolar transistor is a three terminal device that consists of two p-n junctions formed by connecting two doped materials in a region. One layer is configured as the emitter, one as the collector and one of them is connected to the base. The base current controls the current flowing through the collector and emitter, which is known as the collector-emitter current. The relationship between the base and the collector current is given by the common-emitter current gain, also called beta (β) which can range from 50 to 400 depending on the type of transistor.
