A circuit and method for reducing a propagation delay associated with a comparator and a comparator employing the circuit or method. In one embodiment, the comparator, includes: (1) an input stage that receives a differential input signal and develops therefrom a threshold signal, (2) an output stage, coupled to the input stage, that develops a level shifted single-ended output signal as a function of the threshold signal, and (3) a speed-up circuit, associated with the input stage, that reduces a time period to develop the determinant signal thereby decreasing a propagation delay in developing the level shifted single-ended output signal from the differential input signal.
