Abstract
A design for printed circuit board with reduced susceptibility to common-mode noise includes a first substrate, a differential pair of signal lines with two differential transmission lines laid on the first substrate, a second substrate, a metal layer located between the first substrate and the second substrate, and a grounding layer The second substrate is located between the second substrate and the grounding layer, and a conductive structure is located in the second substrate and couples the metal layer to the grounding layer. A length of the metal layer is substantially equal to a length of each of the two differential transmission lines.
