  • Charge-pumping circuits for a low-supply voltage
    Patent number: 6359501
    Abstract: The present invention relates to a charge-pumping circuit for low-supply voltage. A small charge-pumping circuit was added at the gates of the original Dickson charge-pumping circuit's each stage for bias voltage and the first transistor group was added between well and gate. The second transistor group was added between the gate and drain of original transistor. Thus, the charge-pumping circuit for low-supply voltage can supply a higher positive or negative voltage.
