摘要： An ESD power clamp device includes an ESD detection circuit; a controlling circuit coupled with the ESD detection circuit; a field effect transistor (FET) coupled with the controlling circuit, and an impedance element coupled with the FET. The FET includes a drain terminal coupled with a first supply node; a gate terminal coupled with the controlling circuit; a source terminal coupled with a second supply node via the impedance element; and a bulk terminal coupled with second supply node.
