The step responses of the differential via are solved in terms of rational functions by the generalized pencil-of-matrix (GPOM) method. The macro-π model in terms of the rational functions pairs is obtained through an ABCD matrix transformation. The order of the macro-π model can be reduced without losing the accuracy according to a residue criterion. The equivalent lumped circuits of the macro-π model is synthesized by a lumped circuit extraction method (LCEM). The stability and passivity of the extracted models can be preserved based on this time-domain approach and the macro-π topology. Two examples, one is an asymmentric via and the other is an differential via in four-layer PCB, are used to demonstrate the broadband accuracy of the proposed approach both in time-domain and frequency-domain. © 2006 IEEE. |
