Radio-frequency energy-harvesting IC with DC-DC converter
This paper presents an energy harvesting system that uses a radio frequency (RF) signal. It consists of an RF voltage multiplier-rectifier and DC-DC converter. A Dickson voltage multiplier is used as the RF voltage rectifier. A buck-boost converter is used as the DC combiner. The input frequency of the RF signal is 2.4 GHz, and the output DC voltage is programmable. The proposed harvesting system is implemented in a 0.18-um CMOS process.
