Abstract
An off-chip driver (OCD), including a pull-up driver and a pull-down driver, is provided. The pull-up driver and the pull-down driver are coupled to an output pad. One of the pull-up driver and the pull-down driver includes a main driving circuit, an auxiliary driving circuit, a connection circuit, and a common impedance. The main driving circuit is used to perform an output driving operation on the output pad, and the auxiliary driving circuit is used to selectively perform the output driving operation on the output pad. A first terminal of the common impedance is coupled to a driving terminal of the main driving circuit and a driving terminal of the auxiliary driving circuit through the connection circuit. A second terminal of the common impedance is coupled to the output pad.
