    摘要: An ESD circuit is connected with a pad. The ESD circuit includes a P-type transistor, an N-type transistor and a control circuit. A first source/drain terminal of the P-type transistor is connected with the pad. A first source/drain terminal of the N-type transistor is connected with a second source/drain terminal of the P-type transistor. A second source/drain terminal of the N-type transistor is connected with a first node. The control circuit is connected with the pad, the first node, a gate terminal of the P-type transistor and a gate terminal of the N-type transistor. When the pad receives an ESD zap, the control circuit provides a first voltage drop to the P-type transistor and provides a second voltage drop to the N-type transistor, so that the P-type transistor and the N-type transistor are turned on.
