Abstract
A 4× charge pump using exponential topology is proposed and implemented. Comparing to the conventional implementations, the proposed circuit suppresses the reverse current effectively without using different threshold-voltage transistors and additional capacitors. Also, the body effect found in the charge transfer switches is eliminated. The proposed charge pump is analyzed with the state-space method and fabricated using 0.35 μm complementary metal-oxide-semiconductor process. Results show that the output voltages close to the ideal one, and a maximum power efficiency of 95% was recorded.
