Abstract: A single-chip UHF RFID reader that integrates all building blocks—including an RF transceiver, IQ data converters, and a digital baseband—is implemented in a 0.18 μm CMOS process. A high-linearity RX front-end and a low-phase-noise synthesizer are proposed to handle the large self-interferer, which is a key challenge in the reader RX design. Highly reconfigurable mixed-signal baseband architecture for channel-selection filtering is proposed to achieve power optimization for multi-protocol operation with different system dynamic ranges and data rates. The reader dissipates a maximum power of 276.4 mW when transmitting maximum output power of 10.4 dBm and receiving the tag’s response of ─70 dBm in the presence of ─5 dBm self-interferer while occupying 18.3 mm2.
