摘要
A low cost fully integrated single-chip UHF radio frequency identification（RFID） reader SoC for short distance handheld applications is presented.The SoC integrates all building blocks—including an RF transceiver,a PLL frequency synthesizer,a digital baseband and an MCU—in a 0.18μm CMOS process.A high-linearity RX frontend is designed to handle the large self-interferer.A class-E power amplifier with high power efficiency is also integrated to fulfill the function of a UHF passive RFID reader.The measured maximum output power of the transmitter is 20.28 dBm and the measured receiver sensitivity is-60 dBm.The digital baseband including MCU core consumes 3.91 mW with a clock of 10 MHz and the analog part including power amplifier consumes 368.4 mW.The chip has a die area of 5.1×3.8 mm^2 including pads.
