Design and performance evaluation of high-resolution oversampling A/D converters

Abstract

An approach to the behavioural simulation of Sigma Delta A/D converters is presented. Integrator, comparator and digital filtering blocks are implemented with the advantage of being easily interfaced with component designers. Post-processing algorithms for overall performance evaluation are also discussed, specially by focusing on the fact they can largely affect the meaning of the results. Simulation results are presented that confirm the suitability of the proposed simulator and models.<>
