摘要： An ESD protection circuit includes a MOS transistor of a first type, a MOS transistor of a second type, an I/O pad, and first, second, and third guard rings of the first, second, and first types, respectively. The MOS transistor of the first type has a source coupled to a first node having a first voltage, and a drain coupled to a second node. The MOS transistor of the second type has a drain coupled to the second node, and a source coupled to a third node having a second voltage lower than the first voltage. The I/O pad is coupled to the second node. The first, second, and third guard rings are positioned around the MOS transistor of the second type.
