This paper presents a complete set of SIMULINK models, which allow exhaustive behavioral simulations of any sigma-delta modulator to be performed. The proposed set of models takes into account most of the sigma-delta modulator non-idealities, such as sampling jitter, kT/C noise and operational amplifier parameters (noise, finite gain, finite bandwidth, slew-rate and saturation voltages). For each model we present a description of the considered effect as well as all of the implementative details. Simulation results on a second-order switched-capacitor sigma-delta modulator demonstrate the validity of the models proposed.

Abstract
This paper presents a complete set of SIMULINK models, which allow exhaustive behavioral simulations of any sigma-delta modulator to be performed. The proposed set of models takes into account most of the sigma-delta modulator non-idealities, such as sampling jitter, kT/C noise and operational amplifier parameters (noise, finite gain, finite bandwidth, slew-rate and saturation voltages). For each model we present a description of the considered effect as well as all of the implementative details. Simulation results on a second-order switched-capacitor sigma-delta modulator demonstrate the validity of the models proposed.
