Abstract
A supergate having an enabled differential input, a single ended input and a differential output provides high speed communication between electronic cards in an electronic device. The enabled differential input is input to a differential amplifier which is electrically driven by a current source. A differential AND gate having the single ended input as an input is electrically driven by one output of the differential amplifier and provides the differential output. The other output of the differential amplifier is OR'd with one side of the differential output so that the propagation delay for the enabled differential input is essentially the same as that for the single ended input. Current steering is used to provide high speed signal flow through the differential amplifier and the differential AND gate.
