A block-oriented approach to EMI-induced distortion analysis for nonlinear analog circuits

In this work a multi-input block oriented approach for the analysis of distortion effects induced by interfering signals in nonlinear circuits is presented. With the proposed model distortion signals at an arbitrary input port can be investigated. Based on a series reversion approach for the nonlinear behavior, analytical expressions for the spectral components arising from intermodulations between distortion and nominal input signal are derived.
