An inherently balanced electrical supply system for a bus provides improved reliability for bus termination in computer systems. The system is particularly well suited for applications such as personal computer systems. The apparatus includes a single current source that is fed into a feeder line connected to opposite ends of the bus at a point at about the center of the feeder line. The feed path is thus divided into two equal-length segments connected to opposite ends of the bus. Integrated circuit chips connected to the bus, when switched on, draw essentially equal amounts of current through each feeder segment, creating substantially equal voltage drops at both ends of the bus, minimizing the voltage difference. Alternative bus configurations are provided in embodiments of the present invention to suit various board spacing requirements.
