Abstract :
This paper presents the formulation of sensitivity networks for delta-sigma modulators. The sensitivity of the output magnitude with respect to any circuit elements is obtained. The method is fast because some parts of the computations are performed only once, in a pre-processing step. It can be applied to all types and configurations of modulators if all elements are linear except the comparator
