I like the way Dr Johnson explains guard traces and how they work and where to apply them. But there are no hard numbers in this article. Maybe too technical and maybe there's too many variables, but numbers help the argument. I still hear that guard rings should still be used even with a solid ground plane.
Has anyone done a study where they have actual hard numbers showing this one way or another?
Thanks,
Allen
