A resonant charge pump circuit includes a resonant circuit having a bucket capacitor and a bucket inductor connected in series, and a switching circuit connected to the resonant circuit. The switching circuit switches to a first state that enables current to flow from an input terminal into the resonant circuit to charge the bucket capacitor and the bucket inductor, and switches to a second state that enables current to flow from the resonant circuit to discharge the bucket capacitor and the bucket inductor to an output terminal. The resonant circuit controls current flow into and out from the resonant circuit when the switching circuit switches between the states. The resonant charge pump circuit also includes a timing circuit that controls when the switching circuit switches between the states.
