Abstract
Differential signals output by a transfer unit of a latch stage are fed back to a comparator stage as negative feedback signals through a feedback circuit including a differential amplifier comprising two transistors. In this configuration, amplitudes of signals supplied to the transfer unit are stabilized by a feedback effect provided by the feedback circuit to become independent of a through-rate of an input signal supplied to the comparator stage. To be more specific, if the through-rate is high, the amplitudes are reduced, but if the through-rate is low, the amplitudes are increased. As a result, variations in sampling delay related to sampling clock signals are suppressed. With this configuration, for example, harmonic distortions in a flash A/D converter are suppressed as well.
