  • Patent number: 11190194
    Abstract: A digital phase-locked loop has a digitally controlled oscillator with a first coarse tuning field for coarse tuning of the oscillator frequency, a second coarse tuning field for tuning of the oscillator frequency at finer intervals than the first coarse tuning field, and a fine tuning field for tuning the oscillator to an output frequency at finer intervals than the second coarse tuning field. The second coarse tuning field provides open loop tuning and is linear and connected parallel to the first coarse tuning field. The second coarse tuning field provides wide field temperature compensation and frequency error determination at start up based on an interpolated frequency value obtained prior to start up. Faster settling is provided with less complex algorithms.

  • Patent number: 10651857
    Abstract: A phase locked loop system includes bias voltage adjustment circuitry and a voltage regulator that outputs a smoothed core voltage to an oscillator. The bias voltage adjustment circuitry is configured to compute a scaled bias voltage based at least on a target frequency for the oscillator. The voltage regulator is configured to input i) the scaled bias voltage and ii) a selected core voltage that is selected based on the target operating frequency of the oscillator and generate the smoothed core voltage for output to the oscillator.

  • Patent number: 9548746
    Abstract: A phase locked loop system comprises a phase locked loop and an oscillator that is coarse tuned and fine tuned according to coarse tuning operations and fine tuning operations. The system operates to calibrate the coarse tuning of the oscillator based on one or more characteristics related to the oscillator and determined by a characterization component, an interpolation function and one or more final measurements. An adjustment component is configured to adjust the coarse tuning value based on at least one final frequency measurement to generate a final coarse tuning value and set the coarse tuning of the oscillator based on the final coarse tuning value.

  • Patent number: 8675790
    Abstract: A receiver is provided with a digital signal processing circuit to process a receive signal. In addition, the receiver includes an interference detector to detect an interference scenario affecting reception of the signal by the receiver. Depending on the interference scenario detected by the interference detector, the digital signal processing circuit is adapted.
