A phase-locked loop is provided. The phase-locked loop includes a first loop including a con-trolled oscillator and a phase detector. The controlled oscillator is configured to generate an oscillation signal. The phase detector is configured to generate first signal indicative of a timing difference between a reference signal and the oscillation signal. Further, the phase-locked-loop includes a second loop configured to generate a second signal indicative of a timing error of the oscillation signal's cycle time, and to generate a correction signal based on the second signal. The phase-locked loop additionally includes a combiner configured to generate a control signal for the controlled oscillator by combining the correction signal and a third signal derived from the first signal.
