摘要

This brief presents an auxiliary feed-forward noise cancellation (AFFNC) technique that can be applied to a generic Type-II ring oscillator (RO) PLL. The AFFNC technique uses a stand alone sub-sampling phase detector (SSPD) embedded into an alignment loop to extract and cancel noise from the RO output. Along with AFFNC, which uses one reference edge for noise extraction, a Double Sampled AFFNC (DS...
