Abstract
Electrostatic Discharge (ESD) protection scheme includes a divided rail structure to route damaging ESD away from sensitive circuitry. Specifically, V and V rails are divided to segregate the ESD current within a circuit, thus isolating the sensitive circuitry from ESD exposure. In an exemplary embodiment, V is divided into V -esd and V core, while V is divided into V -esd and V core. The structure in cooperation with diodes, clamps and resistors enables to isolate the rails (V core and V core) associated with sensitive circuitry from ESD current.
