Abstract:
A signaling system comprising:a first and a second plurality of switches, wherein each switch of the first and second plurality of switches is coupled to a corresponding current source, wherein, in response to one of a plurality of control signals, one of first and second terminals of each switch of the first and second plurality of switches is coupled to the corresponding current source; a first plurality of conductors, each conductor of the first plurality of conductors having a first end and a second end wherein each first end is coupled to different pairs of switches of the first plurality of switches; a second plurality of conductors, each conductor of the second plurality of conductors having a first end and a second end wherein each first end is coupled to different pairs of switches of the second plurality of switches; and a first and a second plurality of comparators, each comparator of the first and second plurality of comparators having a first input and a second input wherein the first and second inputs of the first plurality of comparators are coupled to different pairs of second ends of the first plurality of conductors and the first and second inputs of the second plurality of comparators are coupled to different pairs of second ends of the second plurality of conductors.
