Abstract

A self-consistent electromagnetic analysis of multiconductor transmission lines is presented for high-speed, high-density MMIC's and VLSI interconnects. In contrast to classical approach, this analysis handles the multiconductor as normal dielectric with high conductivity in electromagnetic simulation. Therefore, dispersion and loss effects can exactly be described in this model. Examples of interconnect circuits with up to four conductors are analyzed for dispersion and frequency-dependent losses. Propagation characteristics of multimode along symmetrical and asymmetrical multiconductor are obtained. Some inherent influences of losses on high-density interconnects and physical dependence of these effects are also discussed.
