A power management integrated circuit for an energy autonomous device is presented. It is based on a configurable 2:1 switched capacitor converter that is capable of delivering a maximum current to always-on and duty-cycled loads equal to 5 μ A and 2 mA, respectively, from a thin-film 4.2-V lithium battery. The circuit is designed and implemented using the 0.8-μ m CMOS transistors of a BCD technology and exploits off-chip ceramic capacitors. Power conversion efficiency as high as 93% in the active mode and 80% in the sleep mode, despite the large variation range of the output current, is achieved.
