A method for searching the limit cycles of high order sigma-delta modulators
2009 European Conference on Circuit Theory and Design
In this paper an approach for description and validation of potential limit cycles of high order Sigma-Delta modulators is presented. The approach is based on a parallel decomposition of the modulator. In this representation, the general N-th order modulator is transformed into a decomposition of low order, generally complex modulators, which interact only through the quantizer function. The decomposition considered helps to describe easily the time domain behavior of the modulator. Based ondoi:10.1109/ecctd.2009.5275042 dblp:conf/ecctd/Mladenov09 fatcat:kailia6jefh4xniutmyme4lhlq
