This paper presents a solution to mitigate the signal vias to power plane coupling using controlled-return-current guard traces with shorting vias. The proposed design allow to considerably suppress the noise due to uncontrolled return path of the current coupled to power planes in multilayered packages and boards, avoiding signal integrity and electromagnetic interference problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
