MOS Charge Pump for Sub-2.0V Operation
A new charge-pump circuit is proposed in this paper. Two major factors limiting the
charge pump gain and efficiency, are the threshold voltage drop and body effect. In this
paper, the positive charge- pump circuit uses the charge transfer switches and floating well;
therefore, it can reduce the threshold voltage drop and the body effect problems. Due to the
new circuit scheme, the proposed charge- pump circuit can be used in a conventional
n-well CMOS process for low supply voltage and have high charge pump gain and
efficiency.
