Abstract
This invention provides a resistance-adjustable means using at a pull-up driver and/or a pull-down driver of an OCD circuit. When the resistance-adjustable means is applicable to the pull-up driver, the resistance-adjustable means includes a triode-mode PMOS coupled to a circuit of the pull-up driver and at least one of one or more adjustable resistors and/or a fixed resistor, which are connected in series and coupled to the triode-mode PMOS, and the at least one of the adjustable resistors or the fixed resistor is coupled to an IO (input/output) pad. When the resistance-adjustable means is applicable to the pull-down driver, a triode-mode NMOS is used to replace the triode-mode PMOS for the resistance-adjustable means.
