Philsar Semiconductor Inc.

The invention provides ESD protection for IC's while isolating the different power supplies from one another. A network in the IC has a plurality of circuit cells through which the IC receives power. Each circuit cell provides localized electrostatic discharge protection. With each circuit cell coupled to a global node through a dual current direction coupling network and with portions of the global node physically separating the circuit cells, any noise, interference, or stray ESD current generated by a circuit cell is shunted away from other circuit cells to the global node. An off-chip ground connection coupled to the global node provides a destination for this noise or interference.
