“…Hence, this paper presents two main ways to reduce noise coupling: shortening the distance and making back-drill. Furthermore, these two ways are verified in three different cases, including broadside coupling power plane coupling , orthogonal coupling the VR vias coupling to the signal line , and vertical coupling the VR vias coupling to the signal transmission via [1].…”

“…The proposed way is expected in the prior art, but there are only offered simulation results in the frequency domain, and it is hard to estimate the impact in the pre-simulation stage [1]. Despite the other studies proposing that the crosstalk results only focus on VR switching noise coupling signal lines, different coupling paths are needed to consider nowadays [2,3].…”

The voltage regulator switching noise is an unavoidable problem in the server system. It degrades the signal integrity of the signal trace nearby the VR area. Two effective ways to reduce VR noise are shortening the distance and making back-drill. This paper verified these two ways by simulating three cases: power plane coupling, VR vias coupling to signal line, and VR vias coupling to signal vias. Finally, it shows that shortening distance and making back-drill significantly reduce crosstalk in the frequency and time domains.
