Claim 0:
1. A circuit comprising:
a conductive contact disposed on a top side of a circuit board structure comprising one or more layers of a circuit board;
a conductive path disposed on an opposed bottom side of the circuit board structure;
a via structure extending through the one or more layers of the circuit board, the via structure interconnecting the conductive contact and the conductive path; and
a group of metallic structures embedded in the circuit board directly beneath a bottom end of the via structure and separated from the bottom end of the via structure by a dielectric material, the group of metallic structures and the conductive path having a same width to decrease an impedance difference between the via structure and the conductive path;
wherein the group of metallic structures and a portion of the conductive path that is connected to the via structure have a same perpendicular width that is perpendicular to the conductive path; and
wherein the group of metallic structures further has a parallel width that is the same as the perpendicular width, the parallel width being a width of the group of metallic structures that is parallel to the conductive path.
