Abstract
An analog-to-digital converter has a sampler to hold a sampled signal, an input signal predictor to generate a prediction signal at predetermined timing before a signal level of a ramp signal that monotonically increases or monotonically decreases with time crosses a signal level of the sampled signal, a comparator to compare signal levels of the ramp signal and the sampled signal to output a comparison signal showing whether the signal level of the ramp signal is larger than the signal lever of the sampled signal, a first counter to perform a count operation in synchronism with a first clock signal within a period from start of a comparison operation by the comparator to generation of the prediction signal, and a second counter to perform a count operation in synchronism with a second clock signal.
