A 1.2µW SIMO energy harvesting and power management unit with constant peak inductor current control achieving 83–92% efficiency across wide input and output voltages

This paper presents a single inductor energy harvesting and power management (EHM) unit for ultra-low power (ULP) systems. The proposed circuit harvests energy from solar cells from 0.38V input voltage (Vin) and provides 4 output voltages - storage at 5V and VDDs at 3.3V, 1.5V and 1.2V. A peak inductor current control scheme enables high efficiency… CONTINUE READING
