Reference-Noise Compensation Scheme for Single- Ended Package-to-Package Links # Reference-Noise Compensation Scheme for Single- Ended Package-to-Package Links ![](/sites/default/files/styles/wide/public/publications/figure_1_s.png?itok=08sZquZf) We present a method for tracking and compensating the reference noise in single-ended links, enabling energy-efficient package-to-package communication in systems with noisy environment. The 25Gb/s/pin serial link with compensation loop is fabricated in 16nm FinFET process operating over PCB channel with >200mV reference noise. The maximum measured bandwidth of the compensation loop is 30MHz, and its energy and area penalty are negligible. ## Authors [Xi Chen](/person/xi-chen) [Nikola Nedovic](/person/nikola-nedovic) [Stephen Tell](/person/stephen-tell) [Sudhir Kudva](/person/sudhir-kudva) [Brian Zimmer](/person/brian-zimmer) [Trey Greer](/person/trey-greer) John Poulton (NVIDIA) [Sanquan Song](/person/sanquan-song) [Walker Turner](/person/walker-turner) [John Wilson](/person/john-wilson) [Tom Gray](/person/tom-gray) ## Publication Date Monday, February 17, 2020 ## Published in [2020 International Solid-State Circuits Conference](http://isscc.org/) ## Research Area [Circuits and VLSI Design](/research-area/circuits) ## Uploaded Files [09063140.pdf](https://research.nvidia.com/sites/default/files/pubs/2020-02_Reference-Noise-Compensation-Scheme//09063140.pdf "Open file in new window")1.46 MB ## Copyright This material is posted here with permission of the IEEE.
