Abstract: An electronic static discharge protection apparatus provided. A plurality of ESD circuits serially coupled between a pad and a internal circuit, a first stage ESD circuit includes a ESD element directly coupled to the pad, and a last stage ESD circuit includes an inductive element directly coupled to the internal circuit, so as to improve electronic discharge protecting ability of the ESD protection apparatus and increase circuit operation bandwidth without signal loss attenuation.
