Abstract
A high performance ESD protection circuit is provided. Embodiments include a circuit having an RC clamp circuit including a first NMOS transistor having a first source, drain, and gate, a current mirror circuit including first and second PMOS transistors having a second and third source, drain, and gate, respectively, and an SCR circuit including a first P+ contact. The first source is coupled to a ground rail, the first drain is coupled to the second drain, second gate, and third gate, the second and third sources are coupled to a power rail, and the third drain is coupled to the first P+ contact, wherein during an ESD event the first NMOS and PMOS transistors turn on to discharge a first current to the ground rail, and the current mirror provides a second current to the first P+ contact for turning on the SCR.
