Figure 8-1: Common-emitter amplifier with resistive load. (a) Circuit, omitting biasing details. (b) Low-frequency hybrid-pi model developed so far. This results in a maximum incremental gain [1] for ...

If you do your biasing correctly, your amplifier output bias level will not drift significantly with time, temperature or component variations. Let s consider the simple bias circuit shown in Figure 5 ...

As understood from Chapter 5, the bipolar junction transistor is a current amplifier of its own. However, it can be made to amplify voltage also, as will be discussed in this chapter. The key factor ...
