Abstract
High-speed pulse propagation on terminated dual-level interconnects is investigated. The interconnects, modeled as multiconductor microstrip embedded in a layered dielectric substrate, are analyzed by using a full-wave approach to calculate dispersive eigencurrents, modal impedances, and mode speeds. The effects of dispersion on digital signal propagation are assessed upon comparison with results calculated using a frequency-independent TEM analysis. Termination effects are studied by investigating an example of five parallel running dual layered circuit level interconnects, with two lines on one plane and three on the other.
