Passivity-preserving model order reduction of linear time-varying macromodels

Abstract

We study model order reduction (MOR) of continuous-time linear time-varying (LTV) systems. Examples include circuit or interconnect models found in VLSI marco-modeling. Specifically, a time-varying version of positive-real balanced truncation (PRBT), called LTV-PRBT, is proposed, which preserves the passivity of LTV systems for stable global simulation… (More)
