1. What is BJT TransistorBJT transistors are three-terminal active devices made of two PN junctions, which are interacted with each other and fabricated on single crystals of semiconductor germanium or silicon to form a PNP (or NPN) structure. The N-type region in the middle is known as the Base (B), and the P-type regions on both sides are known as the Emitter (E) and the Collector (C), each of w...
