COMPUTING DEVICE AND METHOD FOR ENFORCING PASSIVITY OF SCATTERING PARAMETER EQUIVALENT CIRCUIT

摘要

A computing device and a method for scattering parameter equivalent circuit reads a scattering parameter file from a storage device. A non-common-pole rational function of the scattering parameters in the scattering parameter file is created by applying a vector fitting algorithm to the scattering parameters. Passivity of the non-common-pole rational function is enforced if the non-common-pole rational function does not satisfy a determined passivity requirement.
