Abstract:
This article presents a low-jitter sub-sampling chopper phase-locked loop (SS-CPLL) that incorporates a novel chopping charge pump (C-CP) to mitigate 1/f noise in short-channel devices operating at a low supply voltage of 0.75 V. A charge-share cancellation technique is introduced to suppress ripple generated by residual charge from the previous reference …
