Abstract:
A comparator circuit having at least three inputs, the comparator circuit comprising:a first inversion circuit associated with a first input node of the comparator circuit;a second inversion circuit associated with a second input node of the comparator circuit; andat least one additional inversion circuit associated with an additional input node of the comparator circuit, wherein at least one of the first and second input nodes is coupled to an output of the at least one additional inversion circuit, and the additional input node associated with the at least one additional inversion circuit is coupled to an output of at least one of the first and second inversion circuits, and further wherein the comparator circuit is operative to generate a decision output signal indicative of a difference in input signal values associated with the first, second and additional input nodes ofthe comparator circuit.
