Abstract
Provided is a clock generator that includes a comparator in which characteristics of two input signals vary over time. A voltage controller, having a resistor and at least one constant current source, generates a direct current (DC) voltage proportional to an output current of the constant current source and a resistance value of the resistor. The comparator compares a ramp voltage generated by the voltage controller with the DC voltage.
