ON STABILITY OF MULTIPLE-FEEDBACK DELTA-SIGMA MODULATORS

K. Olejarczyk

Abstract

In this paper a new method of proving stability of Delta-Sigma modulators in the way of bounding outputs of integrators has been described. The presented approach is theoretical as well as computational. The method has been tested exhaustively for second-order multiple-feedback modulators.
