A synthesis technique of time-domain interconnect models by MIMO type of adaptive least square method

説明

This paper describes an efficient synthesis technique of time-domain models for interconnects characterized by sampled data. In this method, poles are derived from sampled data in the frequency domain. Next, the dominant poles and the residues are obtained efficiently by a MIMO (multi-input multi-output) type of adaptive least squares method. Furthermore, time-domain models are derived from the frequency domain models. Finally, the accuracy and efficiency of the proposed method are substantiated by transient simulation of an example circuit using this model.
