Abstract:
1. An electrostatic discharge (ESD) protection circuit comprising: 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, wherein 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; and an inductor electrically coupled between the anode and the second P-type semiconductor material wherein an electrical path from the anode to the inductor to the second P-type semiconductor material excludes the first and second N-type semiconductor materials or between the cathode and the first N-type semiconductor material wherein the electrical path from the cathode to the inductor to the first N-type semiconductor material excludes the first and second P-type semiconductor materials.
