Abstract
A novel design for a low-power DC-DC converter using high-efficiency charge pump circuits is proposed. It uses a gate pumping circuit to decrease the conduction power loss of the charge pump circuit. The output voltage and current of the proposed DC-DC converter consisting of five charge pump circuits operating at 3.3 V are 18 V and 100 muA. The power efficiency and the ripple voltage of the designed charge pump circuits are 82.3% and 20 mV.
