Abstract
A circuit for optimizing the operation of a comparator capable of rail-to-rail operation and relatively high speed. The optimized comparator can output relatively narrow pulses in response to an input signal swinging between the rails of the power supply. Further, the comparator can provide an indication of an under voltage condition of an input signal with respect to a reference voltage. Also, the comparator can conserve power consumption by disabling those portions of the comparator that are not currently employed to resolve a high or low swing of the input signal.
