Abstract
The invention presents a rectifier circuit and a rectification method for harvesting light energy and RF energy, which uses light energy receiver to convert light energy into input direct-current voltage and RF energy receiver to convert RF energy into RF voltage simultaneously. Also, by combining with injection-locked oscillating circuit, oscillating frequency of injection-locked oscillating circuit is locked according to RF frequency also amplitude of RF voltage is enhanced. By using rectifier circuit to rectify and output corresponding output direct-current voltage, both light energy and RF energy may be harvested simultaneously and energy conversion efficiency is enhanced.
