Abstract:
1. A non-uniform differential transmission line pair to reduce cross talk from an aggressor transmission line, the non-uniform differential transmission line pair comprising: a first transmission line on a first layer and a second transmission line on a second layer, each of the first transmission line and the second transmission line having a dielectric layer disposed between the first transmission line and the second transmission line, wherein the first transmission line and the second transmission line are positioned such that a quasi-twisted pair of transmission lines is effected with the first transmission line sections of the first and second transmission lines being in parallel and spaced apart by a selected transverse separation distance, the second transmission line sections of the first and second transmission lines being in parallel and overlapping each other, and the third transmission line sections of the first and second transmission lines being in parallel and spaced apart by the selected transverse separation distance; and a first ground plane over or under the first transmission line and the second transmission line.
