Abstract
An integrated circuit including a signal connection pad, an electrostatic discharge (ESD) protection circuit, and an input stage circuit is provided. The ESD protection circuit is coupled to the signal connection pad. An input terminal of the input stage circuit is coupled to the ESD protection circuit. The input stage circuit includes a load circuit, a current source circuit, an input transistor, and an impedance circuit. A control terminal of the input transistor is coupled to the ESD protection circuit. A first terminal of the input transistor is coupled to the load circuit. A second terminal of the input transistor is coupled to the current source circuit. A first terminal of the impedance circuit is coupled to a body of the input transistor. A second terminal of the impedance circuit is coupled to a first voltage.
