They are highly durable, smaller in size and operates on a low voltage supply. A Transistor is a three terminal device All types of transistor amplifiers operate using AC signal inputs which alternate between a positive value and a negative value so some way of presetting the amplifier circuit to operate between these two maximum or peak values is required. This is achieved using a process known as Biasing. Biasing is very important in amplifier design as it establishes the correct operating point of the transistor amplifier ready to receive signals, thereby reducing any distortion to the.

Because an amplifier must have two input and two output terminals, a transistor used as an amplifier must have one of its three terminals common to both input and output as shown in Fig 3.6.1. The choice of which terminal is used as the common connection has a marked effect on the performance of the amplifier When a transistor works in an active region the transistor acts as an Amplifier and when it works as a Switch it works in Cutoff and Saturation Regions. The transistor in a Cutoff State both collector base and the Emitter base junctions are reverse biased. Whereas in the saturation region both junctions are forward biased Yes, of course, a transistor works as an Amplifier. In fact, it's one of the two things that transistors normally do.
