In SIMULINK-model of a Delta-Sigma ADC, we have a non-ideal multibit DAC in the feedback loop. The DAC mismatch noise will be shaped according to a general Data Weighted Averaging (DWA) transfer function 1±z^(-D), where D is a positive integer (delay). The DWA element selection logic calculates a selection vector. The selection vector chooses, which of the unit DACs will be used at each sample time. Fixed-point blocks are used to construct the DWA block. Requirements: - MATLAB 7.6 (R2008a)

Requirements: No special requirements

Platforms: Windows, Mac, *nix, Mac OSX, Linux, Matlab , Solaris

Keyword: Delta-sigma, Delta-sigma Adc, Dwa Mismatch, Model, Simulink, Simulink Model
