Abstract
A digital compensation of an input stage of a comparator may be achieved by providing switched load elements, which may be appropriately connected to the differential input pair of the comparator in order to match transistor characteristics of the input pair and also match the load value of the input stage. Thus, enhanced offset behavior may be accomplished without providing an external signal and/or without requiring complex reference voltages/currents.
