    摘要: An electrostatic discharge (ESD) clamp circuit is provided, which includes a plurality of identical module circuits. The anode of the first module circuit is coupled to the cathode of the ESD clamp circuit. The anode of each of the other module circuits is coupled to the cathode of the previous module circuit. The cathode of the last module circuit is coupled to the ground terminal of the ESD clamp circuit. Each module circuit includes a conduction path and a detection circuit. The detection circuit is coupled to the anode, the cathode and the conduction path of the module circuit. When the rising speed of the voltage at the anode of the module circuit surpasses a threshold value, the detection circuit makes the conduction path conducting.
