Sub-sampling phase-locked loop (SSPLL) achieves lower in-band phase noise compared to a conventional charge-pump phase-locked loop with frequency dividers. Recently, several works have been reported to enable fractional-N operation of SSPLL to broaden its applications. However, they require careful...
