A charge pump circuit is disclosed. The charge pump circuit comprises a transfer capacitor receiving a first clock phase and a driving capacitor receiving a second clock phase, the second clock phase opposite to the first clock phase. The circuit includes a first switch coupling an input node to the transfer capacitor. The first switch being controlled by the driving capacitor. The circuit further includes a second switch coupling the input node to the driving capacitor. The second switch being controlled by the transfer capacitor. The circuit also includes a third switch coupling the transfer capacitor to an output node. The third switch being controlled by the driving capacitor. The third switch operating in phase opposition to the first switch. The circuit finally includes a charge storage capacitor coupled to the output node.
