Zusammenfassung: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.
