Mahmoud H. Ouda, et al., "Self-biased differential rectifier with enhanced dynamic range for wireless powering." IEEE Transactions on Circuits and Systems II: Express Briefs 64, (5), 2017, 515. A self-biased cross-coupled differential rectifier is proposed with enhanced power-conversion efficiency (PCE) over an extended range of input power. A prototype is designed for ultrahigh-frequency (UHF) 433-MHz radio-frequency power-harvesting applications and is implemented using a 0.18-μm CMOS technology. The proposed rectifier architecture is compared with the conventional cross-coupled rectifier

Abdullah S. Almansouri, et al., "A CMOS RF-to-DC Power Converter With 86% Efficiency and− 19.2-dBm Sensitivity." IEEE Transactions on Microwave Theory and Techniques 66 (5), 2018, 2409. Abstract: This paper proposes an RF-to-dc power converter for ambient wireless powering that is efficient, highly sensitive, and less dependent on the load resistance with an extended dynamic range. The proposed rectifier utilizes a variable biasing technique to control the conduction of the rectifying transistors selectively, hence minimizing the leakage current; unlike the prior work that has a fixed feedback

Abdullah Almansouri, et al., "A Dual-Mode Nested Rectifier for Ambient Wireless Powering in CMOS Technology." IEEE Transactions on Microwave Theory and Techniques, 68 (5) , 2020, 1754. This article proposes (DM) nested radio frequency (RF) rectifier for ambient wireless powering. The proposed architecture utilizes a DM nested feedback circuit to enhance the conductivity of the rectifier at low power while reducing the reverse leakage current at high power by generating supply voltages at the gates of the pMOS rectifying transistors. The proposed rectifier is fabricated in a 65-nm CMOS
