A new power-rail electrostatic discharge (ESD) clamp circuit for application in 3.3-V mixed-voltage input-output (I/O) interface is proposed and verified in a 130-nm 1-V/2.5-V CMOS process. The devices in this power-rail ESD clamp circuit are all 1-V or 2.5-V low-voltage nMOS/pMOS devices, which are specially designed without suffering the gate-oxide reliability issue under 3.3-V I/O interface applications. A special ESD detection circuit realized with the low-voltage devices is designed and added in the power-rail ESD clamp circuit to improve ESD robustness of ESD clamp devices by substrate-triggered technique. The experimental results verified in a 130-nm CMOS process have proven the excellent effectiveness of this new proposed power-rail ESD clamp circuit
