Abstract

This paper presents a steady-state small-signal analysis method for nonlinear circuits. The method can be used to calculate the steady-state time domain representation as well as the frequency response of switched-capacitor circuits. Any nonideal models for switches can be used, i.e., all modeling levels of MOSFETs as switches including parasitic components can be simulated. The method proposed may be applied to mixer analysis for the case of a strong LO and a weak RF signal to calculate the steady-state solution, the spectrum, or the conversion gain. An example is given to demonstrate that the method proposed is efficient and sufficiently fast to simulate switched-capacitor circuits. The simulation results show good agreement with transient analysis
