Abstract :
A charge pump based on the cross-coupled structure generates a 2x VDD output. The circuit delivering 10 mA@VDD = 0.9 V from a single NiMH battery is designed in a commercial 0.35 mum CMOS process. The design operates at a supply voltage as low as VDD = 0.9 V with efficiency of better than 80% and the maximum VDD is 1.4V. The implementation method of the cross-coupled charge pump is summarized in this paper.
