Abstract:
A clock signal generator can include a clock signal generation unit that is configured to generate a clock signal. A clock signal control unit is configured to count a number of pulses of the clock signal during a reference time, and to compare the number of pulses with a reference value to provide a comparison result, and to generate a control signal based on the comparison result, where the clock signal generation unit increases or decreases the number of pulses of the clock signal based on the control signal.
