Transistor amplifiers

Abstract

In this chapter we look at the basic design and operation of transistor amplifiers. Whilst it may seem that this is an exact scientific process, there remains an element of experience or ‘art’ in the selection of component values. Nothing, in fact, is precise or exact, and there is always an element of uncertainty about the operating values associated with a transistor. For example, one of the objects of transistor circuit design is to remove the effect of, for instance, the variation in current gain between transistors in a production batch.
