  • Phase locked loop with precise phase and frequency slope limiter
    Patent number: 8957711
    Abstract: Phase slope is controlled in a phase locked loop wherein a phase error signal controlling a controlled oscillator has a proportional component and an integral component, by determining whether the proportional component falls within a range bounded by upper and lower limit values. The proportional component is combined with the integral component if the proportional component falls within the range to provide the phase error signal. Otherwise, the proportional component is modified to meet a phase slope requirement while leaving the integral component unmodified. The modified proportional component is combined with the unmodified integral component to provide the phase error signal.
