ABSTRACT:
The invention relates to methods and structures for connecting circuits and circuit elements processing electrical signals having very fast transition times, including sub-nanosecond transition times. It includes a connecting structure for connecting a multiplicity of signal lines at a common point to reduce unwanted reflections thereat; a single or multi-conductor female connector for receiving thin elements such as ribbon cable ends, printed circuit (PC) board edges, and the like; a structure for connecting together a multiplicity of ribbon cables terminating in such multi-conductor female connectors, and a further structure for connecting together a multiplicity of such multi-cable connectors to obtain maximum packing thereof, and minimum conductor lengths thereto, to obtain processing rates up to twenty-fold over what is available with present connecting methods and structures.
