Abstract
A multi-layered printed circuit board having an integrated twisted pair conductor. In a preferred embodiment, the printed circuit board comprises two segmented conductor traces on a first and a second layer of the printed circuit board crisscrossing each other and a plurality of vias. The two segmented conductor traces on the first layer are connected to the two segmented conductor traces on the second layer through the vias. The twisted pair conductor may be shielded by adding a ground trace on either side of the conductor traces and a ground plane both above and below the conductor traces. The conductor traces may also be tuned to specific electrical characteristics by properly spacing the plurality of vias such that a specific number of turns per unit length are achieved. The continuous conductor traces may be further tuned by using a specific dielectric thickness as well as by designing the conductor traces to be of a specific dimension.
