    • A voltage pump circuit for precharging/pumping a charge to/from a pumping capacitor separately employs a voltage generator for independently supplying a well-bias voltage to a PMOS transfer transistor which transfers a charge of a precharged capacitor to produce reference voltage. The voltage of the voltage generator is applied to a well of the PMOS transfer transistor to body bias the PMOS transfer transistor and, thus, ruggedize its threshold voltage transistor.
