This course is about feedback and its influence on analog circuit performance. There are three lectures which cover the following material:
Lecture 1 – Introduction, types of feedback, identifying feedback loops and loop gain, increasing or decreasing resistance at a port, and increasing the bandwidth of an amplifier.
Lecture 2 -Increasing accuracy, decreasing nonlinearity, amplifier linearization, decreasing quantization noise, feed-forward, influence of frequency dependent feedback, influence of feedback on poles and zeros, and multiple loop feedback circuits.
Lecture 3 – Feedback stability, Routh-Hurwitz criterion, open-loop frequency response, Nyquist stability criterion, stability simulation methods, brute force simulation methods, unusual circuit behavior achieved by feedback, and summary.
