    摘要: An interconnect system between an integrated circuit device and a printed circuit board may include a filter between the integrated circuit device and the power subsystem of the printed circuit board. The filter may be a low-pass filter that reduces current in a higher frequency range without negatively modifying current in a lower frequency range and may reduce radiated emissions produced during operation of the integrated circuit. The filter may be implemented by arranging core-power voltage conductors and ground conductors at a first or second level interconnect into one or more voltage groupings and one or more adjacent ground groupings such that series inductance is increased. In some embodiments, the first level interconnect may include conductive bumps or pads between an integrated circuit and a substrate. In some embodiments, the second level interconnect may include solder balls, pins, pads, or other conductors of a package, socket, or interposer.
