An electro-static discharge (ESD) detection circuit is provided. The ESD detection circuit includes: a first power pad for receiving a first supply voltage; a second power pad for receiving a second supply voltage; an RC circuit having an impedance component coupled between the first power pad and a first terminal and having an capacitive component coupled between the first terminal and a second terminal, wherein the second terminal is not directly connected to the second supply voltage; a trigger circuit couples to the first power pad, the second power pad, and the RC circuit, for generating an ESD trigger signal according to a voltage level at the first terminal and a voltage level at the second terminal, and a bias circuit coupled between the first power pad and the second power pad for providing a bias voltage to the second terminal.
