Abstract:
A method and a device for canceling an offset voltage in an output of a comparator circuit include sampling a set of offset voltages; applying a set of correction voltages equal in magnitude and opposite in polarity to the set of offset voltages, the set of correction voltages being applied to an output generating arrangement of the comparator circuit; and enabling output of the output generating arrangement after the set of correction voltages is applied.
