Modeling of multiconductor buses and analysis of crosstalk, propagation delay and pulse distortion in high speed GaAs logic circuits

Abstract

Crosstalk, propagation delay, pulse distortion in multiconductor buses for high-speed GaAs logic circuits are analyzed. A simple but accurate quasi-TEM model of the bus is developed, and a critical analysis is carried out both on the accuracy of different approximate lumped and distributed models and on the impact of such approximations on the time-domain response. Results on the behavior of multiconductor buses in the presence of realistic input waveforms, are presented and design criteria are obtained. >
