INTEGRATED CIRCUIT

摘要

An integrated circuit is provided. The integrated circuit includes a pad, a core circuit, an impedance matching component, a first switch and a second switch. The pad is configured to transmit a communication signal. A communication terminal of the core circuit is coupled to the pad, and a power terminal of the core circuit is coupled to a system voltage rail. A first terminal of the impedance matching component is coupled to the pad. A first terminal of the first switch is coupled to the system voltage rail, and a second terminal of the first switch is coupled to a second terminal of the impedance matching component. A first terminal of the second switch is coupled to a control terminal of the first switch, and a second terminal of the second switch is coupled to the second terminal of the impedance matching component.
