Passive macromodels of microwave subnetworks characterized by measured/simulated data

Passive macromodeling of microwave components, high-speed packages and interconnect modules characterized by simulated/measured data has generated immense interest during the recent years. This paper presents an efficient algorithm for addressing passivity of macromodels from simulated/measured data, based on linear formulation. Also one of the critical issues involved in such macromodels is the passivity check and compensation. For this purpose, a new theorem and an efficient algorithm is presented. Examples are presented to demonstrate the validity and efficiency of the proposed algorithm.
