Charge pump circuit having independent inverted and non-inverted terminals |
摘要 |
A charge pump circuit including two transfer capacitors, two reservoir capacitors and a plurality of switches. The transfer capacitors are charged to Vin when the charge pump circuit is in a first operating state, the transfer capacitors are connected in a first series arrangement to apply a +2 Vin charge to one of the reservoir capacitors when the charge pump circuit is in a second operating state, and the transfer capacitors are connected in a second series arrangement to apply a -2 Vin charge to the other of the reservoir capacitors when the charge pump circuit is in a third operating state. A control circuit is provided to control the plurality of switches such that the charge pump circuit enters the first through third operating states is a predetermined sequence.
