Abstract

In this paper a combined random-conjugate-gradient algorithm has been used to approach optimization problems in which the feasibility area contains more than one minimum. This optimization is performed upon device equivalent electrical models using a sequential windowing technique applied to time domain measurements. The optimization process is described, and has been applied to some cases for which results are presented and discussed
