Summary: | The present invention provides an apparatus and methods for the functionality of an integrated circuit. An exemplary embodiment according to an aspect of the present invention includes a ball grid array having open spaces therein. Within the open spaces, pairs of opposite polarity vias are clustered to minimize current path inductance by exploiting mutual inductance between vias of opposite current flow. In an illustrative embodiment, capacitors are coupled to the vias to further reduce current path inductance. |
