Abstract
A novel fully-differential current comparator is proposed which is based on a double folded-cascode structure. Thanks to an offset and charge-injection compensation, it provides a sensitivity as good as 20 nA. Moreover, it achieves a switching time better than 30 ns with a 0.5-μA input step current while dissipating 45 μW
