Passivity-preserving frequency weighted model order reduction techniques for general large-scale RLC sytems

This paper presents passivity-preserving frequency-weighted model order reduction (MOR) techniques for general large-scale RLC systems. Three techniques (Enns´, Wang´s and Lin and Chiu´s) which preserve only stability and not passivity are generalized to include passivity in this paper. Conditions under which the passivity is preserved are also derived. Simulation results are also presented to show the effectiveness of the proposed generalization.
