Abstract
An electrostatic discharge (ESD) protection circuit includes an input terminal, a power supply line and a source of reference potential. The circuit also includes a dummy supply line. A Schottky barrier diode is connected between the input terminal and the power supply line for blocking voltages from the input terminal which are greater than the power supply voltage. A first clamping structure is connected between the dummy supply line and the source of reference potential, and a second clamping structure is connected between the power supply line and the source of reference potential. A first clamping diode is connected between the input terminal and the dummy supply line and a second clamping diode is connected between the input terminal and the source of reference potential.
