Abstract
A 16-phase 8-branch charge pump with finger boost capacitor is proposed to increase the power efficiency and it is implemented in a 0.35 μm high-voltage CMOS IC technology. Compared with the standard capacitor, the finger capacitor can significantly reduce the parasitic capacitance. By combining the charge recycling method and the finger capacitor, the proposed four-stage charge pump can achieve an efficiency of 47.2% and an output voltage of 13.7 V from a 3 V power supply. The proposed charge pump also has better current driving ability and the area of the chip is 2.32 mm × 0.28 mm.
