Abstract: An electrostatic discharge (ESD) protection circuit is provided. The ESD protection circuit includes an impedance device coupled between a pad and a power line and a clamp unit coupled between the pad and a ground line, wherein no ESD current flows through the impedance device when an ESD event occurs at the pad.
