Abstract
A clock generation circuit, which generates an output clock using an external clock as a target clock, includes a circuit arranged to change the output clock to high level in synchronization with an up edge of the target clock, circuits arranged to generate first and second ramp voltages with a period of interval between neighboring up edges of the target clock, and a circuit arranged to hold a comparison voltage corresponding to a second ramp voltage when an up edge of the target clock occurs. The level of the output clock is changed from high level to low level based on a comparison result between the first ramp voltage and the comparison voltage.
