Abstract:
Structures and methods for electrostatic discharge (ESD) device control in an integrated circuit are provided. An ESD protection structure includes an input/output (I/O) pad, and an ESD field effect transistor (FET) including a drain connected to the I/O pad, a source connected to ground, and a gate. A first control FET includes a drain connected to the I/O pad, a source connected to the gate of the ESD FET, and a gate connected to ground. A second control FET includes a drain connected to the gate of the ESD FET and the source of the first control FET, a source connected to ground, and a gate connected to the I/O pad.
