Abstract:
A representative electrostatic discharge (ESD) protection circuit includes a silicon-controlled rectifier comprising an alternating arrangement of a first P-type semiconductor material, a first N-type semiconductor material, a second P-type semiconductor material and a second N-type semiconductor material electrically coupled between an anode and a cathode. The anode is electrically coupled to the first P-type semiconductor material and the cathode is electrically coupled to the second N-type semiconductor material. The ESD protection circuit further includes an inductor electrically coupled between the anode and the second P-type semiconductor material or between the cathode and the first N-type semiconductor material.
