This paper presents a sub-mW fractional-N all-digital phase-locked loop (ADPLL) with scalable power consumption, which achieves an figure of merit (FOM) of -246 dB.
This paper presents a fully-synthesizable fractional-N injection-locked PLL in 65 nm CMOS.The power consumption is 2.5 mW and 2.2 mW, corresponding to an FoM of -234.4 dB and -246.7 dB.
