摘要：
This paper presents a rectifier for passive UHF RFID tags with high power conversion efficiency (PCE) over a wide incident power range under the influence of mismatch between tag antenna and chip, which benefits read and write sensitivities simultaneously. Fabricated with 0.13 mu m CMOS technology, the RF frontend adopting this rectifier achieves PCE higher than 25% with incident power from -19.2dBm to -7.6 dBm.
