The main difference between BJT and MOSFET is their charge carriers. There are two kinds of transistors namely PNP and NPN. The two regions are named the P-junction and N-junction. Actually, a BJT is a silicon piece that includes three regions and two junctions. This transistor consists of three terminals namely the emitter, base, and collector. Fundamentally, the operation of a BJT transistor is determined by the current at the base terminal. The BJT is a current-controlled device where the o/p of the base terminal or emitter terminal is a function of the current in the base terminal. A bipolar junction transistor is one type of semiconductor device and in the olden days, these devices are used in the place of vacuum tubes.
