Abstract: A frequency multiplier includes a first ring oscillator, a second ring oscillator that is turned on complementarily to the first ring oscillator, a combining circuit that combines a first output signal of the first ring oscillator and a second output signal of the second ring oscillator to generate a final output signal, and a calibration circuit that corrects a discontinuous pulse included in the final output signal based on feedback of the final output signal.
