Abstract	This work presents an inductor less switched capacitor based energy harvester, which can simultaneously harvest from 2 energy sources (Solar + Piezo). The proposed harvester employs 2D maximum power point tracking algorithm, by changing the conversion ratios of the charge pumps for piezo and solar sources, and 1D voltage regulation algorithm through varying the switching frequency. The proposed 2D MPPT can match the input impedance of two sources simultaneously. Implemented in 65nm CMOS, the proposed harvester can generate 1.8-2.5V output while delivering 35uW to 70uW power with a peak efficiency of 74.6%.
