Abstract
An off chip driver circuit includes a first power rail, a second power rail, an input/output pad, a pull-up circuit, a pull-down circuit. The pull-up circuit is configured to selectively activate at least one of charging paths between the first power rail and the input/output pad. The pull-up circuit includes a first resistor and PMOS transistors arranged on the charging paths, and the first resistor is coupled between the first power rail and the PMOS transistors. The pull-down circuit is configured to selectively activate at least one of discharging paths between the second power rail and the input/output pad. The pull-down circuit includes a second resistor and NMOS transistors arranged on the discharging paths, and the second resistor is coupled between the second power rail and the NMOS transistors.
