An Active Capacitance Multiplier Based on Switched-Capacitor DC-DC Converter

Abstract:

A technique of replacing the floating capacitor by an active capacitance multiplier is proposed in this paper, in order to overcome the difficulty in fabrication of the large capacitors in monolithic integrated circuits. The simulation results show that the same output characteristics can be obtained from the new charge pump with a capacitor much smaller than that adopted in the normal charge pump products. Therefore, the new charge pump is much easier to be fabricated in fully integrated realizations with on-chip capacitor.
