Abstract :
In this paper a block-oriented approach for the susceptibility analysis of nonlinear analog circuits is proposed. Using a multi-input Wiener model the effects of interfering signals at an arbitrary circuit node can be examined. The proposed model separates the linear dynamic from the static nonlinear behaviour of the examined circuit. By this means, the frequency behaviour of the nominal and the interfering signal can be investigated. The description of the static nonlinearity by a power series approach leads to analytic expressions for the emerging intermodulation products at the circuit´s output.
