ABSTRACT:
A low power communications bus uses a current source at one end of a transmission line, and a driver at the other end of the transmission line which generates a logic state based on the sensed current level. The invention is particularly suited for interconnecting a computer processor and its on-board caches. The driver at the load end of the transmission line includes an induction coil, and a magnetoresistive element located adjacent the coil. Separate ground planes can be provided for the coil and the magnetoresistive element, to avoid ground loops.
