Abstract

In an AD converter circuit, a comparison circuit includes: a differential comparison circuit configured to perform comparison determination of differential input signals based on an internal clock signal and generate first differential output signals indicating a determination result; a determination assist circuit configured to receive the first differential output signals and generate second differential output signals; a latch circuit configured to hold the second differential output signals and generate third differential output signals; and a clock generation circuit configured to generate the internal clock signal based on the third differential output signals. The determination assist circuit varies a value of the first differential output signals and generate the second differential output signals when a designed time has elapsed with values of the first differential output signals being unvaried from a reset value since the start of an operation of the comparison determination in the differential comparison circuit.
