✦ Synopsis

This paper presents an accurate and simple model for dc gain nonlinearity of operational amplifiers used in the switched-capacitor circuits such as the sigma-delta modulators. The proposed model can simply be used in the time-domain system level simulation of sigma-delta modulators to evaluate the effect of amplifier's dc gain nonlinearity on the overall linearity of the modulator as well as in the other switchedcapacitor circuits as explored in the paper.
