Abstract
An input/output (IO) circuit includes a first bias circuit and a second bias circuit coupled to a node. A first capacitor and a second capacitor are being cascaded and coupled to the node. The node is defined between the first capacitor and the second capacitor. A pad is coupled to the node. The first bias circuit maintains a voltage at the node below a threshold during a transmit mode and a receive mode of the IO circuit and the second bias circuit maintains the voltage at the node below the threshold during the receive mode. The voltage at the node is dependent on a voltage at the pad during the receive mode.
