Abstract
A filter structure includes a capacitive device and an inductive device. The capacitive device includes a ground plane in a first metal layer of an integrated circuit (IC) package, a plate in a second metal layer of the IC package, and a dielectric layer between the ground plane and the plate. The inductive device includes first and second conductive paths in a third metal layer of the IC package, each of the first and second conductive paths is electrically connected to the plate and has a width w, the first and second conductive paths are separated by a spacing s, and a ratio s/w has a value ranging from 1 to 2.
