Unit VI: Bipolar Junction Transistor | BCA 2nd Semester Fundamentals of Electrical and Electronics Notes Pdf

A Bipolar Junction Transistor (also known as a BJT or BJT Transistor) is a three-terminal semiconductor device that may amplify or magnify a signal by using two p-n junctions. It is a gadget that is controlled by current. The base, collector, and emitter are the three terminals of the BJT. A BJT is a kind of transistor in which the charge carriers are both electrons and holes.

When a tiny signal is applied to the transistor's base, it is amplified and accessible at the collector. The BJT provides amplification in this case. The amplification method does, however, need the use of an external DC power supply.
