Moment-matching is a widely used technique in analysis

design

and fast evaluation of signal transmission performance of interconnects in today's deep submicrometer VLSI design.The construction of exact moment-matching models for distributed RLC transmission lines involves a tedious and complicated procedure using previous methods.This paper provides a simple approach to derive such models based upon observations on the Maclaurin expansion of the ABCD matrix of the transmission line.In addition

a new method is proposed for the interconnects delay estimation

which can be used not only to the common second order model

but also to the third order

and even higher-order models.
