Imbedded PCB AC coupling capacitors for high data rate signal transfer

摘要

A method and apparatus for coupling high speed data components using imbedded PCB AC coupling capacitors is disclosed. The capacitor comprises a first and a second conductive plate of polygonal shape coupled to surrounding circuitry at the polygonal vertices of the polygonal plates. This configuration results in improved capacitor performance, particularly with respect to capacitive impedance and reflected waves for high bandwidth signals at the frequency ranges of interest.
