A novel wideband embedded decoupling structure that eliminates bypass capacitors by controlling resonances

Power supply decoupling networks are essential elements of electronic products for reasons of both signal integrity and the control of emissions. Such networks are large and underdamped, resulting in numerous resonances that can exacerbate crosstalk and emissions problems. They also use a large number of components and occupy a significant amount of space. This paper proposes a novel, patent pending, charge-storage basement (CSB) structure that eliminates the need for most discrete bypass capacitors and squelches resonances by incorporating perimeter damping without increasing dc losses. The performance of an example structure is evaluated by computing supply-point impedance functions using a full-wave simulator across a frequency range at various points on the structure.
