Abstract:
Electrostatic discharge (ESD) protection is provided in using a supply clamp circuit using an ESD event actuated MOSFET device. Triggering of the MOSFET device is made at both the gate terminal and the substrate (back gate) terminal. Additionally, the MOSFET device can be formed of cascoded MOSFETs.
