More Information
Summary:A method and apparatus for model-order reduction and sensitivity analysis, is disclosed. It has been known that reduced-order models can be yielded using the congruence transformation, which contains information of circuit moments of both circuit network and its corresponding adjoint network. By exploring symmetric properties of the modified nadal analysis (MNA) formulation, the method needs only half of the system moment information compared with the previous ones. Passivity of the reduced-order model is still preserved. The relationship between the adjoint network and the sensitivity analysis will also be disclosed. Keyword: keduced-order model, congruence transformation, modified nadal analysis, adjoint network, sensitivity analysis.
