Abstract
First transistors for charging respective one side nodes of a plurality of capacitors are connected to these nodes of the capacitors, respectively. Second transistors for outputting electric charge of each capacitor are connected between respective one side nodes of the capacitors and an output terminal, respectively. A plurality of third transistors for transferring the electric charge of the other side nodes of the capacitors to the other nodes are connected to the respective other nodes. The electric charge of each capacitor is serially transferred from nodes of a high electric potential to nodes of a lower electric potential through one path by sequentially controlling the third transistors, or the electric charge of each capacitor is parallel transferred between arbitrary nodes of a high electric potential and low nodes through a plurality of paths. By these operations, electric charge of each capacitor is recycled.
