A time-domain full-wave extract-ion method of frequency-dependent equivalent circuit parameters of multiconductor interconnection lines

A time-domain full-wave method for the extraction of frequency-dependent equivalent circuit parameters of multiconductor interconnection lines is presented in this paper, The circuit parameters extracted by this method can be inserted into circuit simulation software to investigate time-domain responses of high-speed IC system with multiconductor interconnects, Because the definitions of the voltage and the current are not unique in full-wave analysis, transformation among circuit parameters according to different definitions of the voltage and current is also presented, The method is based on the finite-difference time-domain (FDTD) method, and the reliability of this method is illustrated by its application to representative problems.
