20150028938 | CHARGE PUMPING DEVICE - A charge pumping device includes unit cells. Each unit cell includes first and second cells, each including a charge transfer circuit, a switch controlling a charge transfer operation thereof, and a charge storage circuit having a first end connected to an output terminal of the charge transfer circuit. The switch of the first and second cell is controlled by a first and second clock and the output terminal of the second and first cell, respectively. The first and second clocks are inputted to a second end of the charge storage circuit of the second and first cells, respectively. A first interface circuit connects first and second cells of a first unit cell to second and first cells of a second unit cell, respectively. Output terminals of a final unit cell connect to a load capacitor. Input terminals of an initial unit cell connect to a supply voltage. | 01-29-2015 |
