A transistor has three regions: the emitter, the base, and the collector, forming two p-n junctions: the emitter-base (EB) junction and the collector-base (CB) junction. The way these junctions are biased determines the operating region of the transistor. For a transistor to function as an amplifier, it needs to operate in the active region . In the active region:
