Macromodeling of electronic circuits based on model order reduction

Abstract

This paper presents practical results of realization and testing of the most famous approaches of model order reduction (MOR) for analog devices in Matlab. The key feature of presented approaches is their realization using mathematical operation singular value decomposition (svd). This paper includes examples of applying methods of model order reduction of linear systems, model order reduction of linear systems with a set of terminals, and model order reduction of nonlinear systems through piecewise-liner approximation. Devices, whose modeling is defined in this paper, contain elements with distributed parameters. Simulink was used to describe devices, developed modules Matlab were used for MOR.
