Model-order reduction of frequency-dependent interconnects based on integrated congruence transform

This paper presents a new technique for the analysis of interconnects characterized by frequency dependent per-unit-length (FD-PUL) parameters. The proposed technique is based on using the idea of integrated congruence transform (ICT) to construct a reduced model in the form of ordinary differential equations (ODEs). The passivity of the reduced model is guaranteed. Numerical results demonstrate the validity of the proposed technique.
