In this paper, a novel model for single-bit internal quantizer Sigma Delta-modulators is presented. It is shown that this model can be used for an exact stability prediction of these systems. Furthermore, it is explained how the necessary computations can be performed in a numerically efficient way by means of a mixed integer linear program (MILP).
