Abstract
A frequency multiplier is disclosed. A plurality of voltage regulators each regulate levels of voltages at first and second common nodes in response to a corresponding one of input signals from a voltage-controlled delay line. An input buffer charges the first node or discharges the second node in response to a feedback signal. An output buffer regulates a level of a voltage at an output node and outputs a frequency-multiplied clock signal and the feedback signal corresponding to the voltage level of the output node. A discharge circuit discharges the first node before a rising edge of each of the input signals from the voltage-controlled delay line is inputted. A charge circuit charges the second node before the rising edge of each of the input signals from the voltage-controlled delay line is inputted.
