摘要:
Methods and systems for compensating reducing jitter produced by a phase-locked loop are disclosed. For example, in a particular embodiment, a phase-locked loop device for reducing jitter may include a voltage-control oscillator (VCO) signal configured to produce a VCO signal, phase-detection circuitry configured to compare an input signal and the VCO signal to produce a phase error signal, and slew-rate limiting circuitry configured to receive the phase error signal and apply a slew-rate limit process on the phase error signal to produce a modified error signal.
