Abstract

This paper presents a reconfigurable high efficiency Switched Capacitor DC-DC Converter targeting ultra-low power applications. The Switched Capacitor utilizes multiple gains to provide variable output voltage (1V, 0.8V and 0.6V). The design modulates both switching frequency and transistor size depending on the load current in order to minimize the losses associated with the Switched Capacitor. The Switched Capacitor is implemented using 65nm Low Power CMOS process technology, spice simulation shows power efficiency above 65% over a wide range of load current from 10 μA to 1mA. The power efficiency reaches its peak value of 85% at low load current of 500 μA.
