This work presents a power management architecture for an On-Chip solar energy harvesting system applied to low power applications. A functional Power Management Circuit with MPPT was designed using a 0.13 µm CMOS technology. The system provides an output voltage of 1.2 V and supply a maximum current of 13.7µA by using just one external inductor. The proposed fractional open circuit voltage MPPT, along with the DC/DC converter controller, allows the system to achieve efficiencies of up to 81%. Such high efficiency was achieved via a self synchronize diode and a negative level shifter reducing drastically the power losses.
