摘要

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 0.18-\mu {m} CMOS technology, and the chip area is 1.15 \times 0.57{mm}{2}. The proposed system can achieve an RF-DC power conversion efficiency greater than 20% in a 16.5-dB input power range with a peak value of 45%, and sensitivity of-16 dBm for a 1-V output voltage.
