    摘要: Apparatus and methods are provided for oscillators having adjustable gain. An exemplary oscillator module comprises a first node for a first voltage, a control node for a control signal, and oscillator circuitry coupled to the first node and the control node. The oscillator circuitry generates an output signal with a first oscillation frequency based on the first voltage, and in response to the control signal being asserted, the oscillator circuitry generates the output signal with a second oscillation frequency based on the first voltage. The second oscillation frequency is greater than the first oscillation frequency.

    摘要: Apparatus, systems and methods are provided for digital phase-locked loops. A digital phase-locked loop comprises an oscillator module configured to generate an output signal and a phase detection module coupled to the oscillator module. The phase detection module is configured to signal the oscillator module to adjust a frequency of the output signal by a first amount when a phase difference between a reference signal and the output signal is less than a threshold amount, and signal the oscillator module to adjust the frequency by a greater amount when the phase difference is greater than the threshold amount.
