Abstract

A circuit device includes a first circuit, a second circuit, and a comparator array section. The first circuit has a first DLL circuit having a plurality of delay elements, and delays a first signal. The second circuit has a second DLL circuit having a plurality of delay elements, and delays a second signal. The comparator array section has a plurality of phase comparators arranged in a matrix, the first delayed signal group from the first circuit and the second delayed signal group from the second circuit are input to the comparator array section, and the comparator array section outputs a digital signal corresponding to a time difference in the transition timing between the first signal and the second signal.
