Settling Time Minimization of Operational Amplifiers

摘要

Settling time is one of the most important performance parameters for a whole class of amplifier, such as those employed in switched-capacitor-based circuits and analog-to-digital converters. In this work, analysis to predict and to minimize the settling time for amplifiers characterized by first-, second-, and third-order system-wise behaviour, is developed. The proposed method is very useful for design purposes. It allows amplifier poles to be placed directly in the complex plane, achieving the best-settled time response in accord with the desired accuracy level.
