Semiconductor ESD circuit and method
Abstract:
In an embodiment, an electrostatic discharge (ESD) circuit for providing protection between a first node and a second node includes a first MOS device having a first source/drain coupled to a first node, and a second source/drain coupled to an intermediate node. The ESD circuit also includes a first capacitor coupled between a gate of the first MOS device and the first node, a first resistor coupled between the gate of the first MOS device the intermediate node, a second MOS device having a first source/drain coupled to the intermediate node, and a second source/drain coupled to the second node, a second capacitor coupled between a gate of the second MOS device and the first node, and a second resistor coupled between the gate of the second MOS device and the second node.
