AN ACCURATE TIME-DOMAIN INTERCONNECT MODEL OF TRANSMISSION-LINE NETWORKS

In this paper, we present a new time domain model of interconnects mod eled as transmission Line networks, Each element of the characteristic s of a transmission line is modeled by a principal part and a remainde r. The principal part consists of an impulse and an exponential functi on, whose Laplace transform matches the original function at infinity frequency with order 1 and at zero frequency with order 0. The remaind er in the time domain consists of a cubic polynomial for a single line and a piecewise cubic polynomial for coupled lines, The model is stab le, accurate, simple, and efficient to use.
