Modeling Bandpass Sigma Delta Modulators in SIMULINK
S. Brigati(2), F. Francesconi(2), P. Malcovati(1)and F. Maloberti(3)
Abstract: In this paper we present a complete set of behavioral SIMULINK models for the
simulation of switched-capacitor band-pass sigma-delta (BP ΣΔ) modulators. The models include
most of the non-idealities which affect the performance of these circuits, such as sampling
jitter, kT/C noise and operational amplifier parameters (noise, finite gain, finite
bandwidth, slew-rate and saturation voltages). With the proposed models it is possible to
accurately predict with fast simulations the signal-to-noise and distortion ratio and the linearity
of any BP ΣΔ modulator.
