    Abstract: PROBLEM TO BE SOLVED: To obtain two ways of use for enabling finding out the advantageous use of a charge pump MOS voltage booster and boosters of this type. SOLUTION: A voltage booster is equipped with four MOS transistors (M1, M2, M3, M4) in place of a classical diode showing an undesirable voltage drop and with an oscillator having two output terminals and two corresponding charge transfer capacitors, in place of a classical oscillator of a single output having relevant charge transfer capacitors. In this method, the undesirable voltage drop substantially does not exist, and ripples are reduced without making a circuit complicated.
