Chapter 8. Voltage Feedback Op Amp Compensation
Ron Mancini
8.1. Introduction
Voltage feedback amplifiers (VFA) have been with us for about 60 years, and they have been problems for circuit designers since the first day. You see, the feedback that makes them versatile and accurate also has a tendency to make them unstable. The operational amplifier (op amp) circuit configuration uses a high gain amplifier whose parameters are determined by external feedback components. The amplifier gain is so high that, without these external feedback components, the slightest input signal would saturate the amplifier output. The op amp is in common usage, so this configuration is examined in detail, but the results are applicable to many other voltage feedback ...
