Un circuit redresseur CMOS à haut rendement pour les applications RFID UHF a été développé. Le redresseur utilise un schéma d'auto-annulation Vth (SVC) dans lequel la tension de seuil des MOSFET est annulée en appliquant une tension de polarisation de grille générée à partir de la tension de sortie du redresseur lui-même. Une configuration de circuit très simple et des caractéristiques de dissipation de puissance nulles lors de la polarisation permettent une excellente efficacité de conversion de puissance (PCE), en particulier dans des conditions de faible puissance d'entrée RF. Dans des conditions de puissance d'entrée RF plus élevées, le PCE du redresseur diminue automatiquement. Il s'agit de la fonction d'autorégulation de puissance intégrée. Le redresseur CMOS SVC proposé a été fabriqué avec un processus CMOS de 0.35 µm et les performances mesurées ont été comparées à celles des redresseurs nMOS, pMOS et CMOS conventionnels ainsi qu'à d'autres types de redresseurs d'annulation Vth. Le redresseur CMOS SVC atteint 32 % du PCE dans des conditions de puissance d'entrée RF de -10 dBm. Ce PCE est plus grand que les redresseurs signalés à ce jour dans ces conditions.

Abstract: A high-efficiency CMOS rectifier circuit for UHF RFID applications was developed. The rectifier utilizes a self-Vth-cancellation (SVC) scheme in which the threshold voltage of MOSFETs is cancelled by applying gate bias voltage generated from the output voltage of the rectifier itself. A very simple circuit configuration and zero power dissipation characteristics in biasing enable excellent power conversion efficiency (PCE), especially under small RF input power conditions. At higher RF input power conditions, the PCE of the rectifier automatically decreases. This is the built-in self-power-regulation function. The proposed SVC CMOS rectifier was fabricated with a 0.35-µm CMOS process and the measured performance was compared with those of conventional nMOS, pMOS, and CMOS rectifiers and other types of Vth cancellation rectifiers as well. The SVC CMOS rectifier achieves 32% of PCE at the -10 dBm RF input power condition. This PCE is larger than rectifiers reported to date under this condition.
