Abstract
A Direct Current (DC) charge comparator that provides low input offset by feeding complimentary plus and minus charge inputs to a single amplification path via an alternate input path switch. Multiple sample and hold circuits at the output of the amplification path permit comparison of the result when each of the charge inputs travels down each of the paths, to determine a correction.
