Abstract
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 switched- capacitor circuits as explored in the paper.
