Abstract
An apparatus to prevent supply-to-ground current in a comparator is disclosed. The apparatus includes circuitry to determine if first and second output nodes of the comparator have respectively reached first and second logic levels, and circuitry responsive to a determination that the voltage at the first and second output nodes of the comparator has reached the first and second logic levels, to generate a signal. In addition, the apparatus includes circuitry to supply the signal to a transistor, the signal to turn off the transistor and prevent the flow of supply-to-ground current through the comparator.
