Abstract:

This paper presents a 32kHz input and 960MHz output low-power charge-pump phase-locked loop (CP-PLL) with a novel loop-filter resistor noise reduction technique and reverse sub-threshold leakage compensated source switched charge pump. The resistor noise reduction technique involves no additional active component / power overhead and hence, more beneficial than existing solutions. The PLL with minimum analog supply voltage of 1.62V and minimum digital supply voltage of 0.65V; with die area of 0.15mm2 is designed and fabricated in 28nm STMicroelectronics FDSOI process. The silicon measurement results have been included. Performance includes an integrated jitter of 530ps, reference spur of -65dBc and current consumption of 600μA.
