Analysis of switched-capacitor network with nonideal op amps using analog circuit simulation program

Two new methods for analyzing the effects of the nonideal op amp on the frequency-domain response of switched-capacitor networks using an analog circuit simulation program are presented. The main idea is based on dealing with the problem in the s-domain or in the transformed domain (p-domain) rather than in the z-domain. By incorporating the indefinite admittance matrix technique, these methods provide two efficient computer-aided techniques for the analysis of general SCNs with single-pole op amps. One can then determine the technical specifications of the op amps required by SCN without tedious analysis.<
