Amplifiers

Abstract

Amplifiers turn a small signal into a larger, more powerful version of the same. Mastering amplification is useful in itself as well as an important exercise in circuit design. Amplifier characteristics include gain, noise, and bandwidth. This chapter concentrates on the design of MOSFET amplifiers. The basic characteristics of op amps are introduced and op amp topologies useful for amplification are described. Design examples include a two-stage amplifier for a low-impedance load and an op amp electret microphone amplifier.
