Abstract
A clock generating device includes: a DDS circuit that generates a periodic signal; and a comparator that compares an input signal and a reference signal and outputs a binary signal. The clock generating device includes a rate-of-change correcting unit that applies correction for increasing a rate of change at a crossing point with the reference signal to the periodic signal generated by the DDS circuit.
