![]() ![]() Hence to achieve faithful amplification, the biasing of the transistor has to be done such that the amplifier operates over the linear region.Ī Class A power amplifier is one in which the output current flows for the entire cycle of the AC input supply. We have already come across the details of transistor biasing, which is very important for the operation of a transistor as an amplifier. Emitter Follower & Darlington Amplifier.Transformer Coupled Class A Power Amplifier. ![]()
