Abstract
The present invention proposes an ESD protection circuit and its related circuits, suitable in an integrated circuit (IC), and coupled between a first pad and a second pad. When a power supply is provided to the IC, a bias generator generates a bias voltage to close the protection component. When the power supply is not provided to the IC, the protection component is always on to release the ESD stress between the first pad and the second pad.
