The almost universal choice in semiconductor power amplifiers is for a unity gain output stage, and specifically a voltage follower. Output stages with gain are not unknown,1 but they are not common. Most designers feel that controlling distortion while handling large currents is hard enough without trying to generate gain at the same time.
The first three parts of this series have dealt with one kind of distortion at a time, due to the monotonic transfer characteristics of small signal stages, which usually, but not invariably, work in class A.2 Economic and thermal realities mean that most output stages are class B, and so we must now consider crossover distortion, which remains ...
