Abstract

An efficient approach is presented for time-domain sensitivity analysis of lossy multiconductor transmission lines with respect to electrical and/or physical parameters. The proposed method employs delay extraction prior to approximating the matrix exponential stamp of the line and guarantees macromodel passivity. A delay-extraction based equivalent circuit for sensitivity analysis is derived in a closed-form, leading to significant computational advantages.
