---|---|---|
This paper presents a high-efficiency radio frequency (RF) power harvesting IC with an extended input range. The proposed system comprises a reconfigurable rectifier, maximum power point tracking unit, load modulation circuit, and low-dropout regulator. The reconfigurable rectifier extends the high-efficiency range of the RF input power through stage number control and load modulation according to input power and load requirements. The design is fabricated using
