This report describes behavioral simulation of ΔΣ analog to digital converters including
the effects of device noise. Simulation of the feedback loop filter s with SpectreRF pro-vides the statistics of the device noise. A discrete time filter is used to generate noise
with similar power spectral density (PSD) during the behavioral simulation. A second
order converter is used to demonstrate the methodology and the simulation results are
presented. Our approach does not make assumptions about the device and quantization
noise adding linearly and takes into account their interaction. It is numerically efficient,
as the behavioral simulation does not require significantly higher computational effort
than in the case that device noise is not in cluded. The same approach can be applied to
continuous time converters
