Abstract
An analog-to-digital converter circuit includes: a first operation amplifier suitable for comparing a ramp voltage and a voltage to be converted so as to produce an amplification result and outputting the amplification result; a second operation amplifier suitable for comparing the amplification result transferred to a first input terminal with a reference voltage transferred to a second input terminal so as to produce a comparison result and outputting the comparison result; a leakage current measurer suitable for measuring a leakage current to the first input terminal; and a leakage current generator suitable for causing a current of the same amount as that of the leakage current measured by the leakage current measurer to flow to the second input terminal.
