Abstract

In this paper the applicability of theory on the stability of perturbed systems on circuit design problems is investigated. The aim of this work is to analytically derive the influence of an EMI disturbance on a differential amplifier stage in specific, by calculating allowed ranges, respectively bounds for the disturbances, as well as for the system itself. The investigated schematic is modelled as a simplified state-space model. The results after applying non-linear systems theory are reviewed by simulation and the practicability of the used approach is discussed.
