POWER AMPLIFIER. 2.0 Introduction. The main characteristics of an amplifier are Linearity, efficiency, output power, and signal gain. In general, there is a trade off between these characteristics. For example, improving amplifier’s linearity will degrade its efficiency.

power amplifier can be regarded as complete until it has proper DC protection – having an amplifier fail is bad enough, but having it fail and take an expensive loudspeaker with it is downright upsetting.
Power amps require a large-signal design methodology: Δ V and Δ I are significant compared with V DQ and I DQ . Power Amp Objective: Get the largest Δ V and Δ I without:
Radio frequency amplifiers used in transmitters can be required to produce thousands of kilowatts of output power, and DC amplifiers used in electronic control systems may also need high power outputs to drive motors or actuators of many different types.
