    Abstract: One embodiment provides a printed circuit board (PCB). The PCB can include one or more metal layers and at least a pair of differential transmission lines. The pair of differential transmission lines can include a first transmission line and a second transmission line. The first transmission line can include a plurality of timing-skew-compensation structures, and a respective timing-skew-compensation structure of the first transmission line or a corresponding segment of the second transmission line adjacent to the timing-skew-compensation structure has a non-uniform width.
