An aggressive approach to parameter extraction

A novel aggressive parameter-extraction (APE) algorithm is presented. Our A PE algorithm addresses the optimal selection of parameter perturbations use d to increase trust in parameter-extraction uniqueness. The uniqueness of t he parameter-extraction problem is crucial especially in the space-mapping approach to circuit design. We establish an appropriate criterion for the g eneration of these perturbations, The APE algorithm classifies possible sol utions for the parameter extraction problem, Two different approaches for o btaining subsequent perturbations are utilized based on a classification of the extracted parameters,The examples include the parameter extraction of a decomposed electromagnetic model of a high-temperature superconducting fi lter, The parameter extraction of an empirical model of a double-folded stu b filter is also carried out.
