Abstract
A multi-layer circuit board includes a first layer having at least first and second conductive traces of different widths and the same impedance. One of a first power plane and first ground plane has a void region such that the first conductive trace is spaced apart from the first power plane by a first thickness, and the second conductive trace is spaced apart from the first ground plane by a second, different thickness.
