This brief proposes the analysis and design of a high-efficiency differential radio-frequency (RF) front-end for electronic-product-code second-generation-compatible RF identification tags. By studying the operating mechanism of an N-stage rectifier using a dynamic compensation technique, we propose a steady-state model to predict its output voltage and power conversion efficiency (PCE). The model...
This paper focuses on synchronization of radio frequency identification (RFID) reader receivers, which plays a significant role for stability and efficiency of RFID systems. Performance of RFID reader suffers from a back-link-frequency variation of tags at a maximum of 22% according to widely used RFID standards. A new synchronization scheme employing timing recovery loop in RFID Reader Receivers...
The reader collision problem occurs when multiple-RFID reader access tags concurrently. The system efficiency and system throughput will decrease greatly in multiple-reader environment. Most proposals in previous study use a single technique to solve the reader collision problem, thus their system throughput is not desirable. A scheme combining time division and frequency division, TFDMA, is proposed...
