This paper presents an ultra-low-power switched-capacitor (SC) voltage boost converter (VBC) with a digital maximum power point tracking (MPPT) control circuit for low-voltage energy harvesting. The proposed digital MPPT control circuit converts analog voltage information of the PV cell into digital values and extracts the maximum power regardless of the harvester’s conditions and load current. Measurement results demonstrated that our proposed digital MPPT control circuit can track the maximum power point of the PV cell successfully. The proposed PMS generated a 2.58-V output voltage from a 0.46-V input voltage. The maxi-mum power conversion efficiency was 63%.
