Sensitivity analysis of distributed parameter elements in high-speed circuit networks

This paper presents an analysis method, based on MacCormack'stechnique, for the evaluation of the time domain sensitivity ofdistributed parameter elements in high-speed circuit networks.Sensitivities can be calculated from electrical and physicalparameters of the distributed parameter elements. The proposedmethod is a direct numerical method of time-space discretization anddoes not require complicated mathematical deductive process.Therefore, it is very convenient to program this method. It can beapplied to sensitivity analysis of general transmission lines inlinear or nonlinear circuit networks. The proposed method issecond-order-accurate. Numerical experiment is presented todemonstrate its accuracy and efficiency.
