Abstract
Abstract A circuit assembly including a plurality of integrated circuit chips wherein electrical interconnections between chips at a relatively large distance from each other are accomplished by a conductor bus comprising a first section including conductors running adjacent and parallel to each other for a distance substantially equal to an integral number of half wavelengths of the base frequency of signals of the circuit and second sections including conductors which sharply diverge toward associated integrated circuit chips for electrical connection therewith.
