Power amplifiers

Abstract

Power amplifiers are designed to provide large output powers and therefore, the voltage gain plays only a minor role. Normally, the voltage gain of a power output stage is near unity and the power gain is thus mainly due to the current gain of the circuit. Output voltage and current must be able to assume positive and negative values. Power amplifiers for which the output current can flow in only one direction are discussed in Chapter 6, and are called power supplies.
