MODELING BAND-PASS SIGMA-DELTA MODULATORS IN SIMULINK

S. Brigati, F. Francesconi, P. Malcovati, F. Maloberti
  • Abstract:
    In this paper we present a complete set of behavioral SIMULINK models for the simulation of switched-capacitor band-pass sigma-delta (BPΣΔ) 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 BPΣΔ modulator.
