Clock generation device and clock generation method using the same

Abstract

A clock generation device includes a delay line that generates a modulated clock signal from a reference clock signal having a first period, a pulse generator configured to receive the modulated clock signal and generate a pulse signal in response to edges of pulses included in the modulated clock signal, and a clock generator that generates a clock signal having a second period distinguished from the first period, based on the reference clock signal and the pulse signal. The delay line generates a first pulse based on the reference clock signal and then generates a second pulse after a time modulated from the first period by a result of multiplying the second period by a first numerical value selected from a plurality of numerical values according to a certain probability.
