Abstract:
The present disclosure relates to a phase-locked loop (PLL) including a frequency detector, a sub-sampling phase detector (SSPD), and a voltage-controlled oscillator (VCO). The frequency detector is configured to receive a reference signal and an output signal, and to generate a coarse-tuning voltage that indicates a frequency difference between the reference signal and the output signal. The SSPD is configured to sub-sample the output signal using the reference signal, and to generate a fine-tuning voltage that indicates a phase difference between the reference signal and the output signal. The VCO is configured to update the output signal based on the coarse-tuning voltage and the fine-tuning voltage.

Claim (Index 1):
A phase-locked loop (PLL) comprising:\n a frequency divider, which is configured to receive an output signal and generate a divided signal by frequency dividing the output signal with a frequency divide ratio; a frequency detector, which is configured to receive a reference signal and the divided signal, and generate a coarse-tuning voltage, wherein the coarse-tuning voltage indicates a frequency difference between the reference signal and the divided signal; a controlled slope buffer configured to receive the divided signal and generate a buffered divided signal, wherein:\n the buffered divided signal and the divided signal have a same frequency; and \n the buffered divided signal has a higher slope and shorter rising time than the divided signal; \n a sub-sampling phase detector (SSPD), which is configured to sub-sample the buffered divided signal using the reference signal, and generate a fine-tuning voltage, wherein the fine-tuning voltage indicates a phase difference between the reference signal and the buffered divided signal; and a voltage-controlled oscillator (VCO), which is configured to adjust the output signal based on the coarse-tuning voltage and the fine-tuning voltage.
