Abstract
An improved method and means for decoupling a printed circuit board are disclosed. A power plane is included having a peripheral edge. The power plane includes a first region and a second region which is separate from and contiguous to the first region. The first region is located from the peripheral edge to a middle portion of the power plane. The first region includes a peripheral portion of the power plane. The second region includes only the middle portion of the power plane. A ground plane is coupled in parallel to the power plane. The ground plane has a peripheral edge. The ground plane includes a first region, and a second region which is separate from and contiguous to the first region. The first region includes the peripheral edge and includes a peripheral portion of the ground plane. The second region includes a middle portion of the ground plane. A first plurality of decoupling elements are connected to the first region of the power plane and to the first region of the ground plane. A second plurality of decoupling elements are connected to the second region of the power plane and to the second region of the ground plane. The first and second plurality of decoupling elem…
