Abstract
A clamping circuit is provided, which may clamp a voltage at a node of a circuit to a stable level by using a transistor already included in the circuit. The clamping circuit may clamp a voltage at a first node of a circuit inside a semiconductor chip to a more stable level when electro-static discharge (ESD) occurs. The clamping circuit may include a transistor and a capacitive element to store a control voltage to turn on the transistor in response to ESD.
