Abstract
Load driving circuits are adjusted to drive loads with fewer or more pull-down devices by sensing the load electrically coupled to the load driving circuit. In particular, capacitance of the load is compared to a threshold capacitance. If the capacitance of the load is less than the threshold capacitance, selected ones of the pull-down devices are disabled, thereby reducing the capacity of the load driving circuit. If the capacitance of the load is greater than the threshold capacitance, selected ones of the pull-down devices are enabled, thereby increasing the capacity of the load driving circuit. The pull-down devices include delay circuits that enable selected transistors after a delay.
