Abstract
The paper presents a methodology and corresponding software tool for simulations of oversampled switched-capacitor delta-sigma modulator. It allows the analysis of non-ideal parameter influence. Among these parameters are parasitic capacitors, limited switch resistances, gain-bandwidth product of active devices. Special attention is passed to analysis of nonlinear properties of stray capacitances and active elements. Simulation of jitter effect is considered us well. The developed program Is based on nodal approach. Volterra series technique and numerical multi-dimensional inverse Laplace transform are used for the nonlinear analysis. Results are illustrated by examples. The program has been written in MATLAB.
