On the stability of sigma delta modulators [PDF]
IEEE Transactions on Signal Processing, 1993 A framework for stability analysis of sigma-delta modulators is presented. It is argued that limit cycles for constant inputs are natural objects to investigate in this context. A number of analytical and approximate techniques to aid the stability analysis of the double loop and interpolative modulators are discussed and lead to ways of improving the ...
