Abstract
An improved analog CMOS comparator circuit is described. The improved circuit incorporates an additional CMOS device in the output stage of a conventional differential comparator. The additional device compensates for current imbalances which occur at relatively high common mode voltages thus allowing the improved comparator to operate over a wider range of common mode input voltages.
