Abstract
A successive approximation register analog-to-digital converter includes: a digital-to-analog converter that generates an analog voltage based on a digital code; a comparator that receives the analog voltage; a control circuit that generates a digital code of an input voltage sampled from an external clock signal by successively changing the digital code based on a comparison result of the comparator; a delay circuit that resets the comparator based on a signal transition generated by delaying the comparison result; and an adjustment circuit that counts a value indicating a number of the signal transition being generated during a cycle of the external clock signal and adjusts a delay of the delay circuit according to a counted value.
