Abstract
Disclosed is a phase-locked loop having a high bandwidth using the rising edge and falling edge of a signal. The disclosed phase-locked loop controls the frequency of a voltage control oscillator by comparing both a phase difference between rising edge of a reference signal and rising edge of a feedback signal and a phase difference between falling edge of the reference signal and falling edge of the feedback signal.
