Efficient construction of passive macromodels for resonant networks

摘要

The present invention provides a system and method that provides a model that simulates response of a multi-port passive circuit over a broadband frequency range. Briefly described, one embodiment comprises determining a plurality parameters of a model corresponding to the multi-port passive circuit, determining a plurality of pole-residue-eigenvalues associated with the determined parameters, identifying at least one pole-residue-eigenvalue having a magnitude less than zero, changing a value of the at least one identified pole-residue-eigenvalue and recalculating at least one of the parameters after the setting the identified pole-residue-eigenvalue to at least zero.
