Sigma-delta modulator: Refinement of equivalent circuit and transfer function

V. S. Golub

Abstract


Analysis of sigma-delta modulator and its models (equivalent circuits) is performed. New refined equivalent circuit of modulator and its transfer function are suggested. Modeling of modulator is performed which confirms results of analysis.


Keywords


sigma-delta modulation; sigma-delta modulator; quantizer; equivalent circuit; transfer function; modelling
