The switched capacitor circuit has pump capacitors to transfer energy and a steady-state operating mode and a pre-charge mode. The pre-charge circuit initially charges the pump capacitors when the switched capacitor circuit operates in the pre-charge mode. It includes a voltage divider stage having one or more nodes, each of which provides voltage at one of a corresponding one or more voltage levels, and a driver stage having one or more cascoded drivers, each of which comprises a first terminal for receiving a drive signal that depends at least in part on a voltage level at a corresponding one of the nodes, and a second terminal for coupling to a pump capacitor and to another of the drivers."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pre-charge of switched capacitor circuits with cascoded drivers","description":"An apparatus for voltage conversion includes a switched capacitor circuit, a pre-charge circuit, a voltage divider stage, and a driver stage.
