Field Effect Transistors in Power Amplifiers
The low drive power requirements of field effect transistors make the idea of using FET's in the power stages of audio amplifiers very attractive. However, economical power FET's with current capability above a few hundred milliamperes are beyond present technology. This paper describes how combinations of present FET's and power transistors behave as power FET's. A Class-B amplifier design is presented to illustrate the technique.
