Reduced-order model for time-domain sensitivity analysis of active circuits
Conventional sensitivity analysis based on model-order reduction techniques guarantee the passivity and, consequently, the stability of the reduced sensitivity circuit provided that the original circuit is passive. This excludes a large class of circuits that are stable but not necessarily passive. In this paper, an efficient model-order reduction method is presented for computing sensitivity information of active stable circuits with respect to arbitrary parameters. The proposed algorithm guarantees the asymptotic stability of the reduced sensitivity model by construction.
