State space stability analysis of sigma-delta modulators

A method for analyzing the stability of sigma-delta modulators is presented. The method is based on the state space representation of a system and can also be applied to other nonlinear systems. Inaccuracies due to the simplified model were avoided by using a discrete time nonlinear model to a modul...

Zusammenfassung:A method for analyzing the stability of sigma-delta modulators is presented. The method is based on the state space representation of a system and can also be applied to other nonlinear systems. Inaccuracies due to the simplified model were avoided by using a discrete time nonlinear model to a modulator, which is as close as possible to the real system.< >
