Abstract
The charge pump circuit, includes an amplifier, a condenser, and a modifying circuit. The amplifier has a plurality of first voltage transfer stages, and each first voltage transfer stage transfers a voltage from an input to an output thereof such that the output voltage equals the input voltage minus a voltage drop. The condenser increases the output voltage at the output of at least one of the voltage transfer stages, and the voltage modifying circuit modifies each increased output voltage to compensate for the voltage drop.
