The present article proposes an approach to evaluate the “quality” of equivalent circuits of complex devices obtained by a novel technique based on constitu- tive subcircuits and particle swarm optimization and to “improve” their performances. In particular, the robustness of the obtained circuits is evaluated by a sensitivity analysis, which leads to the identification of the bounds of its frequency response, since different runs of the global extraction procedure lead to slightly different equivalent circuits (yet topologically coincident). The analysis of the numerical results gives insight on the robustness of a single case and, at the same time, attests to the efficiency of the proposed method.

Abstract
The present article proposes an approach to evaluate the “quality” of equivalent circuits of complex devices obtained by a novel technique based on constitu- tive subcircuits and particle swarm optimization and to “improve” their performances. In particular, the robustness of the obtained circuits is evaluated by a sensitivity analysis, which leads to the identification of the bounds of its frequency response, since different runs of the global extraction procedure lead to slightly different equivalent circuits (yet topologically coincident). The analysis of the numerical results gives insight on the robustness of a single case and, at the same time, attests to the efficiency of the proposed method.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
