Abstract: The present disclosure provides a power clamp device. The power clamp device includes a delay element, a first transistor, a second transistor, and a gate control circuit. The delay element has an input terminal and an output terminal. The first transistor has a gate electrically connected to the output terminal of the delay element. The second transistor has a source electrically connected to a drain of the first transistor. The gate control circuit has a first terminal electrically connected to the input terminal of the delay element, a second terminal electrically connected to the output terminal of the delay element, and a third terminal electrically connected to a gate of the second transistor.

Abstract: The present disclosure provides electrostatic discharge circuits and structures and methods for operating the electrostatic discharge circuits and structures. A circuit includes a first transistor and a second transistor. The first transistor includes a drain, a source, a gate, and a bulk. The drain of the first transistor is connected to a first terminal. The source of the first transistor is connected to receive a first voltage. The gate and the bulk of the first transistor is connected to receive a second voltage. The second transistor includes a drain, a source, a gate, and a bulk. The source, the gate, and the bulk of the second transistor is connected to receive the second voltage. The drain of the second transistor is connected to the first terminal. In response to the terminal reaching a trigger voltage, the first transistor is configured to be turned on.
