Moment Computations of Nonuniform Distributed Coupled RLC Trees with Applications to Estimating Crosstalk Noise

A novel method is proposed to compute moments of nonuniform distributed coupled RLC transmission lines. Recursive formulae of moments of coupled RC trees are ex-tended to those of coupled RLC trees by considering both self inductances and mutual inductances. It can be ob-served that moment computations of distributed lines out-perform those of lumped ones. The inductive crosstalk noise waveform can be accurately and efficiently estimated us-ing the moment computation technique in conjunction with the projection-based order reduction method. Fundamen-tal developments of the proposed approach are described in details. Experimental results demonstrate the improved ac-curacy of the proposed method over that of the traditional lumped methods.
