Abstract
A printed circuit board includes a dielectric substrate; first and second conductive traces disposed on the dielectric substrate; and a compensation structure disposed in the first conductive trace. The compensation structure includes a compensation segment connected in line with the first conductive trace; and a dielectric layer on all or part of the compensation segment. The first and second conductive traces may form a differential signal pair. The compensation segment may limit one or more of signal skew, mode conversion from differential mode to common mode, and impedance variations caused by a bend in the differential signal pair.
