  • Abstract
    This paper presents a boost switched-capacitor power converter (SCPC) in 140nm CMOS converting a wide input voltage range (2.6V to 4.2V) to an output voltage of 5V at 1W output power. It achieves the highest applicable number of conversion ratios with the lowest number of floating capacitors to date. With 8 conversion ratios and only 4 small floating capacitors, a high peak efficiency of 94.5%, a very small PCB area of 8.1mm2, and a low thickness of 0.5mm are achieved.
