Abstract
Printed circuit boards for countering signal distortion are disclosed that include: a conductive pathway on a printed circuit board between a transmitter and a receiver, the conductive pathway comprised of traces and vias connected together for conductive transfer of a signal from the transmitter to the receiver; a parasitic element on the printed circuit board, the parasitic element having a parasitic effect that distorts the signal; and one or more passive elements mounted adjacent to the conductive pathway without connecting to the conductive pathway, the passive elements having a corrective effect to reduce the distortion from the parasitic effect on the signal.
