  • Differential digital-to-time converter for even-order INL cancellation and supply noise/disturbance rejection
    Patent number: 11387833
    Abstract: A method of quantization noise cancellation in a phase-locked loop (PLL) is provided according to certain aspects. The PLL includes a phase detector having a first input configured to receive a reference signal and a second input configured to receive a feedback signal. The method includes delaying the reference signal by a first time delay, delaying the feedback signal by a second time delay, receiving a delta-sigma modulator (DSM) error signal, and adjusting the first time delay and the second time delay in opposite directions based on the DSM error signal.
