Abstract
An electrostatic discharge (ESD) protection apparatus includes at least one first transistor and at least one second transistor. The first transistor includes a control terminal, a first terminal, a second terminal, and a bulk. The control terminal and the second terminal of the first transistor are coupled to each other. The first terminal of the first transistor is coupled to one of a pad and a power rail line. Likewise, the second transistor also includes a control terminal, a first terminal, and a second terminal. The first terminal of the second transistor is coupled to the bulk of the first transistor, the bulk of the second transistor is coupled to the second terminal of the first transistor, and the second terminal of the second transistor is coupled to the other of the pad and the power rail line.
