Abstract

A technology associated with an electrical circuit, in particular, a zero current detection circuit, is disclosed. The disclosed zero current detection circuit includes a plurality of dynamic comparators. Operating clocks of the dynamic comparators are generated by a plurality of flip-flops each configured to latch an output of one dynamic comparator corresponding thereto and then to supply the latched output as a clock of another dynamic comparator downstream of the former dynamic comparator. The dynamic comparators is activated as power is supplied thereto only in a required period of a charging/discharging cycle of a boost type power converter.
