Abstract: This disclosure relates to a system that includes a boost circuit comprising a boost capacitor. The boost circuit is configured to provide a boost voltage at a first terminal of the boost capacitor by increasing the boost voltage at the first terminal to exceed a target voltage for a given charge cycle. A boost switch is configured to supply the boost voltage from the first terminal to a charge node for turning on a transistor, which is coupled to the charge node, based on a boost signal during the given charge cycle. A pull-down circuit is configured to control discharge of the charge node to a clamp voltage that is sufficient to turn off the transistor for the given charge cycle and to facilitate charging of the charge node in a next charge cycle.
