Abstract
Systems and methods are disclosed herein to provide improved electrostatic protection for electrical circuits. For example, in accordance with an embodiment of the present invention, an electrostatic protection device includes: a drain region formed in a substrate; a gate separated from the substrate by a gate oxide; and an isolation region formed in the substrate, the isolation region being adapted to isolate the gate oxide from a DC voltage coupled to the drain region.
