A new static power clamp co-designed with input ESD protection circuit

A new static power clamp circuit integrated with input ESD protection is proposed in this paper. By skillfully incorporating traditional input ESD protection, the proposed circuit replaces the protection resistor by the active switch and merging the signal control circuit into trigger circuit of static power clamp. The proposed circuit is a whole-chip ESD protection scheme that has a low leakage and the excellent ESD performance.
