Abstract
Plated through holes pass through clearances in a ground plane of a circuit board. A conductive collar/spoke arrangement is constructed on the ground plane adjacent the clearance, to provide an inductive component to the coupling between a plated through hole and the ground plane. The inductive component impedes the transfer of high-frequency noise between the through hole and the ground plane. Other embodiments are also described and claimed.
