The bipolar transistor is the most important active circuit element used in modern electronics, and it forms the basis of most linear and digital ics and opamps, etc. Bipolar junction transistors bjt general configuration and definitions the transistor is the main building block element of electronics. Chapter 4 bipolar junction transistors pdf version. The fusion of these two diodes produces a three layer, two junction, three terminal device forming the basis of a bipolar transistor, or bjt for short. Bipolar transistors are called bipolar because the main flow of current through them takes place in two types of semiconductor material.

The transistor is the main building block element of electronics. P and n, as the main current goes from emitter to collector or vice versa. Transistor bias voltages are largely dependent on transistor beta. Read about transistor biasing calculations bipolar junction transistors. The simple twodimensional crystalline structure in fig.
