  • Abstract
    Non-ideal behavior models of switched capacitor sigma delta ADC are presented. The modulator non-idealities such as operational amplifier parameters (GBW, colored noise, SR, saturation voltage and so on), clock jitter, capacitor mismatch, nonlinear switch on-resistance and are included. The operational amplifier nonlinear DC Gain is modeled with emphasis and simulation results show it introduces odd harmonic distortion.
