Product Description
Wide-Range Adaptive RF-to-DC Power
Converter for UHF RFIDs
Abstract— A wide-range, differential, cross-coupled rectifier is proposed with an extended dynamic range of input RF power that enables wireless powering from varying distances. The proposed architecture mitigates the reverse-leakage problem in conventional, cross-coupled rectifiers without degrading sensitivity. A prototype is designed for UHF RFID applications, and is implemented using 0.18 μm CMOS technology. On-chip measurements demonstrate a sensitivity of−18 dBmfor 1 V output over a 100 kΩ load and a peak RF-to-DC power conversion efficiency of 65%. A conventional, fully cross-coupled rectifier is fabricated alongside for comparison and the proposed rectifier shows more than 2× increase in dynamic range and a 25% boosting in output voltage than the conventional rectifier.< final year projects >
