Method and means for decoupling a printed circuit board

A method for decoupling a pair of planes included within a printed circuit board, said method comprising the steps of:

• establishing a power plane including a first region and a second region;
• establishing a ground plane located parallel to said power plane, said ground plane including a first region and a second region;
• establishing a first plurality of decoupling elements connected to said first region of said power plane and said first region of said ground plane;
• and
• establishing a second plurality of decoupling elements connected to said second region of said power plane and said second region of said ground plane.

A printed circuit board, comprising:

• a power plane having a peripheral edge and including a first region and a second region, said second region being separate from and contiguous to said first region of said power plane, said first region being located from said peripheral edge to a middle portion of said power plane, said first region including a peripheral portion of said power plane, and said second region including said middle portion of said power plane;
• a ground plane located parallel to said power plane, said ground plane having a peripheral edge and including a first region and a second region separate from and contiguous to said first region, said first region including said peripheral edge and including a peripheral portion of said ground plane, said second region including a middle portion of said ground plane;
• a first plurality of decoupling elements connected to said first region of said power plane and said first region of said ground plane, a first half of said first plurality of decoupling elements including a plurality of lossy capacitors and a second half of said first plurality of decoupling elements including a plurality of low equivalent series resistance capacitors;
• a second plurality of decoupling elements connected to said second region of said power plane and said second region of said ground plane, said second plurality of decoupling elements further comprising a plurality of lossy capacitors;
• each of said plurality of lossy capacitors of said first and second plurality of decoupling elements including a resistor and capacitor coupled together in series;
• said power plane having a plurality of generally rectangularly shaped portions removed from a conductor of said power plane, each one of said plurality of portions of said conductor removed from said power plane being generally parallel to all others of said plurality of portions of said conductor removed from said power plane;
• said ground plane having a plurality of generally rectangular shaped portions removed from a conductor of said ground plane, each one of said plurality of portions of said conductor removed from said ground plane being generally rectangularly shaped;
• each one of said plurality of portions of said conductor removed from said ground plane being generally parallel to all others of said plurality of portions of said conductor removed from said ground plane;
• and
• each one of said plurality of portions of said conductor removed from said power plane being generally perpendicular to each one of said plurality of portions of said conductor removed from said ground plane.
