Abstract
An apparatus is disclosed that substantially reduces or eliminates the resonance that occurs in vias that connect the layers of a printed circuit board by electrically coupling a first transmission line in a circuit board to a second transmission line in a circuit board by two electrical paths having substantially the same electrical length. The two electrical paths are created by connecting the first transmission line to a first via which is in turn connected to a second via having a second transmission line with a plurality of connecting electrical paths between the two vias. In one illustrative embodiment, electrical traces are used to connect the top of the first via to the top of the second via and the bottom of the first via to the bottom of the second via.
