Abstract
An ESD protection circuit for the pads of an integrated circuit (IC) using silicide-clad diffusions is disclosed. The circuit uses a robust N+ diode with N-well block, an output NFET and a large transient clamp, each with a distributed, integrated N-well drain resistor to prevent the IC from avalanching and leakage during the Human Body Model and Charged Device Model tests for ESD.
