Abstract
A signal channel extends from motherboard to a daughter card across an edge connection. The daughter card includes a conductive plane that is held at a constant electrical potential. In order to compensate for a number of sources of inductance within the signal line at the edge connection, a circuit trace forming a portion of the signal channel includes an enlarged portion, spaced inward along the daughter card from the contact pads forming the edge connection, that adds capacitive coupling of the signal channel with the conductive plane.
