Abstract :
In this paper, an efficient passivity verification algorithm is presented for delayed rational function based macromodels obtained from tabulated scattering parameter data. The proposed approach is based on a new half-size frequency dependent generalized eigenvalue problem, which reduces the necessary search region to a single finite interval along the imaginary axis. Numerical results validating improved efficiency of the proposed algorithm over previous techniques are also presented.
