Bipolar Junction Triodes (BJTs) topics include: The basics of BJT, device structures and physical operations, circuits, current-voltage properties, amplifier design, signal operations and circuit configuration and biasing. A Bipolar Junction Transistor (BJT) is a three-terminal semiconductor device that can amplify signals. It's a current-controlled device that consists of two p-n junctions, a common region called the base, and two outer regions called the emitter and collector.  BJTs are known as bipolar transistors because they involve the operation of charge carriers of both polarities....
