Vias for differential signals are typically of a lower impedance than the signal lines connected to them. The noise and reflected signals resulting in impedance mismatch may require circuits to be operated at a frequency far lower than desired. One or more embodiments of the present invention avoid impedance mismatch in circuits and achieve an advance in the art by providing a via with higher impedance through the addition of split ring resonators (SSRs) to each end of the via.
