Abstract
A multi-mode electrostatic discharge (ESD) circuit for a semiconductor chip comprises first and second ESD diodes. In a first mode, a body voltage greater than a power source voltage of the semiconductor chip is applied to the first ESD diode and a body voltage less than a ground voltage of the semiconductor chip is applied to the second ESD diode. In a second mode, a body voltage substantially equal to the power source voltage of the semiconductor chip is applied to the body of the first ESD diode and a body voltage substantially equal to the ground voltage of the semiconductor chip is applied to the second ESD diode.
