Abstract:
A circuit capable of providing electrostatic discharge (ESD) protection, the circuit comprising a first set of power rails comprising a first high power rail and a first low power rail, a first interface circuit between the first set of power rails, the first interface circuit having at least one gate electrode, a first ESD device comprising a terminal coupled to the at least one gate electrode of the first interface circuit, and a second ESD device comprising a terminal coupled to the at least one gate electrode of the first interface circuit, the first ESD device and the second ESD device being configured to maintain a voltage level at the at least one gate electrode of the first interface circuit at approximately a ground level when ESD occurs.
