(Originally published in EDN magazine as “Feedback PlotsOffer Insight into Operational Amplifiers” and “Bode PlotsEnhance Feedback Analysis of Operational Amplifiers” on1/19/89 and 2/2/89, respectively.)Feedback plots simplify the analysis of an op amp’s closedloopAC performance by showing bandwidth and stabilityconditions as a function of the op amp’s gain and phaseresponse. These plots also provide insight into noise performanceand the special feedback requirements of circuitssuch as integrating converters, photodiode amplifiers, compositeamplifiers and active feedback circuits.
