Original Abstract Submitted

An off-chip driver (OCD), a pull-up driver of the OCD and the pull-down driver of the OCD are provided. The pull-up driver includes a main current source circuit and a main base circuit. The main current source circuit is connected between a connecting pad and a high reference voltage. The main current source circuit provides a main current value in response to a main control signal. The matching resistance value is associated with the main current value. The main base circuit is connected to the main current source circuit in parallel, and determines a base value of the matching resistance value.
