摘　　要：射频识别(RFID)系统主要由RFID读写器和RFID电子标签两部分组成。给出了高频(13.56MHz)RFID系统中读写器射频模拟前端的电路设计,符合ISO/IEC14443typeA/typeB,ISO/IEC15693和ISO/IEC18000-3中任一个标准的读写器芯片设计均可采用,设计工艺采用了中芯国际0.35μm2P3M混合CMOS技术,并给出了Cadence环境下的仿真结果。Radio frequency identification （RFID） system consists of two major components, one is interrogator（reader） and the other is transponder （tag）. An analog front-end circuit for 13.56 MHz RFID reader was designed, and it was compatible with ISO/IEC 14443 type A/type B,ISO/IEC 15693 and ISO/IEC 18000-3. The circuit was applied to a reader IC with a very well-suited technology and the simulation results were approved by Cadence. The technology was SMIC 0.35 μm three-metal twopoly mixed signal CMOS process.
