A Single-Chip CMOS Transceiver for UHF Mobile RFID Reader

Abstract

A UHF mobile RFID single-chip reader is implemented in a 0.18mum CMOS technology. The reader IC integrates an RF transceiver, a digital baseband modem, an MPU and host interfaces in 4.5 times 5.3mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The RF transceiver draws 61mA from a 1.8V supply and achieves an 8dBm P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1dB</sub> , an 18.5dBm IIP3, and a 4dBm TX power.
