| Abstract: | A novel electrostatic discharge (ESD) power clamp circuit with ultra-low leakage current is proposed. An ESD transient detective circuit with feedback loop is used to reduce the voltage between the bulk and gate of MOS capacitor, which results in a ultra-low leakage current performance of novel circuit. Verified by HSPICE simulation in 65 nm CMOS process, the standby leakage current of novel circuit is 24.13 nA, which is more than two-orders lower than that of the traditional design about 5.42 μA. |
