Abstract:

In this article, we present a differentially injection-locked clock multiplier (ILCM) featuring an ultra-wide frequency tuning range (TR) and low jitter, achieved through a compact folded-inductor-based magnetic-flux cancellation technique. A co-designed series-LC dual-mode quadrature ring oscillator (QRO) and edge-combining frequency doubler operating in the mm-wave band jointly extend the TR …

Abstract:

This work presents a bandwidth augmented sub-sampling phase-locked loop (BASS-PLL) architecture that features simultaneous out-of-band noise suppression by direct and multipath sampling of the ring oscillator’s (ROs) output and in-band noise suppression via an intrinsic sub-sampling mechanism, ultimately combining the benefits of over-sampling PLLs (OS-PLLs) and sub-sampling PLLs (SS-PLLs) …
