ABSTRACT

How a Generic Amplifi er Works Figure 3.1 shows a very conventional power amplifi er circuit; it is as standard as possible. A great deal has been written about this confi guration, though the subtlety and quiet effectiveness of the topology are usually overlooked, and the explanation below therefore touches on several aspects that seem to be almost unknown. The circuit has the merit of being docile enough to be made into a functioning amplifi er by someone who has only the sketchiest of notions as to how it works.
