INTEGRAL CAPACITOR USING EMBEDDED ENCLOSURE FOR EFFECTIVE ELECTROMAGNETIC RADIATION REDUCTION

摘要

In one embodiment of the invention, an integral capacitor includes a power plane (350), a ground plane (340), and a dielectric layer. The power plane (350) has a power surface and a power periphery. The power plane couples power to signals of an integrated circuit operating at a fundamental frequency. The first ground plane (340) have a first ground surface and a first ground periphery. The first ground plane couples ground to the signals. The first ground plane is separated from the power plane by a first distance (H). The first ground surface is larger than the power surface and the first ground periphery extends at least a second distance (S) from the power periphery. The second distance (S) is at least larger than N times the first distance (H). The dielectric layer is formed between the power plane and the first ground plane.
