Abstract:
A group-differential receiver comprising:a plurality of inputs from X external wires, the X external wires for transmitting N bits of information, wherein X is less than 2N but greater than N;a plurality of differential comparators for comparing each of the X external wires to a remaining X-1 other wires in the X external wires, each differential comparator generating a compare output for a pair of wires;a plurality of X majority blocks, each majority block receiving X-1 compare outputs from a group of X-1 differential comparators, each differential comparator in the group having a target wire of the X external wires as a comparator input and one of a remaining X-1 other wires as another comparator input;each majority block outputting a target state of the target wire as a logic state of a majority of the X-1 compare outputs received by the majority block; anda decoder, receiving X target states from the plurality of X majority blocks, for converting the X target states to the N bits of information,whereby the N bits of information are extracted by differential-comparison and majority-detection of the X external wires.
