This paper presents an approach to analyse the stability of continuous time Σ∆ data converters and shows a new method to define optimized parameter sets without a large number of simulations. Thereby the converter is described as a switched system. The presented analysis is based on a state space description which is utilized to express the properties of a stable behaviour. It is shown how the analysis method can be used to optimize the filter coefficients of the modulator by scaling the integrators outputs
