Matrix pencil based realizable reduction for distributed interconnects

We propose a realizable parasitic reduction method for RLGC distributed interconnects. The proposed method generates a reduced order model based on a modified matrix pencil method. By using a set of analytic formulas, this method provides synthesized RLGC elements. This new model is applied to power grid and antenna circuits involving triangular input waveforms, lossy transmission lines and discontinuities of interconnects. The results show better reduction ratio than the standard macromodels and good accuracy compared with the theoretical values.
