摘要： In one embodiment, an energy harvesting system includes multiple-input-multiple-output switched-capacitor (MIMOSC) circuitry comprising a plurality of switched-capacitor circuit units to receive a plurality of direct current (DC) input voltages at respective input terminals of the switched-capacitor circuit unit, combine the received DC input voltages, and provide the combined DC input voltages at an output terminal of the switched-capacitor circuit unit. The energy harvesting system also includes maximum power point tracking (MPPT) circuitry coupled to switches of the switched-capacitor circuit units of the MIMOSC circuitry. The MPPT circuitry is to provide a plurality of switching signals to the switches of the switched-capacitor circuit units. The MIMOSC circuitry is to provide a plurality of DC output voltages to respective loads based on the switching signals from the MPPT circuitry.
