ABSTRACT:
An integrated electrostatic discharge (ESD) device includes a first ESD structure coupled to a pad terminal of the integrated ESD device and a second ESD structure coupled to a ground terminal of the integrated ESD device. The integrated ESD device also comprises a diffusion region that is shared by each of the first ESD structure and the second ESD structure, such that the shared diffusion region forms a portion of at least one semiconductor junction associated with each of the first ESD structure and the second ESD structure.
