Abstract
According to one embodiment, an analog-to-digital converter includes: a digital-to-analog converter configured to generate an analog voltage based on a sampled analog signal and a digital code; a clock generator configured to generate a first clock signal; a comparator configured to receive the analog voltage from the digital-to-analog converter, and perform digital output based on the first clock signal; and a controller configured to generate the digital code based on the digital output of the comparator. The clock generator varies a delay period, which is from the end of sampling of the analog signal to the start of generating the first clock signal, for each sampling of the analog signal.
