Abstract

An 860MHz-960 MHz UHF RFID reader is designed in 0.18- μm CMOS that fully integrates an RF transceiver and a digital baseband. Highly reconfigurable mixed-signal baseband architecture for channel-selection filtering is proposed to achieve optimal power consumption for multi-protocol operation with different system dynamic ranges and data rates. In the talk mode with LNA bypassed, the RX measures a sensitivity of 70 dBm in the presence of a 5 dBm self-interferer. In the listen mode, LNA is turned on, and RX sensitivity is 90 dBm is measured. The TX achieves output power from -9 to lldBm with output P-ldB of 10.4 dBm.
