desired ESD protection ability. All of them are based on a similar circuit scheme with 3-stage inverters to drive the ESD clamp NMOS transistor with large device dimension. In this work, the designs with 3-stage-inverter and 1-stage-inverter controlling circuits have been studied to verify the optimal circuit schemes in NMOS-based power-rail ESD clamp circuits. 2 E" M1 G7 |/ [8 o, D0 m7 G/ d. u, m7 g0 f \
