Analysis of High-Speed Interconnects with Frequency Dependent Parameters

Simulation of large interconnect networks has become a necessity for accurate EMC analysis. The efficiency of moment-matching techniques has made the simulation of high-speed circuits containing large numbers of 2D and 3D interconnect networks practically possible. These methods, however, have so far assumed constant model parameters with respect to frequency. In this paper a new method is proposed to extend moment-matching techniques to the analysis of interconnect networks with frequency dependent parameters. This proposed method is useful for the analysis of frequency dependent transmission lines and rPEEC models, and for determining current distributions in high frequency transmission lines.
