An IC device includes first and second CMOS structures positioned in n-type doped regions of a substrate, the first CMOS structure including a common gate terminal, first NMOS body and source contacts, and first PMOS body and source contacts, the second CMOS structure including a common drain terminal, second NMOS body and source contacts, and second PMOS body and source contacts. The IC device includes a first electrical connection from the common drain terminal to the common gate terminal, a clamp device including a diode, a second electrical connection from a cathode of the diode to the first PMOS body and source contacts, and a third electrical connection from an anode of the of the diode to the first NMOS body and source contacts, and entireties of each of the second and third electrical connections are positioned between the substrate and a third metal layer of the IC device.
