摘　　要：电子标签天线接口是芯片获得能量、时序、数据的接口,其设计的好坏直接影响到电子标签的性能。本文探讨了无源RFID电子标签的天线理论和天线耦合接口的功率传输,提出了电子标签天线接口的优化设计和实现电路,进行了仿真验证,并成功应用到标签芯片设计中,已在SMIC0.35μmCMOS工艺下投片成功。RFID tag＇s antenna interface is used to receive energy, timing and data, and its design quality affects directly the tag＇s performance. This paper discusses the theory of passive RFID tag＇s antenna and power transmission of antenna coupling interface, presents the optimized design of tag＇s antenna interface, including implementation circuit of the antenna interface, and also gives its simulation-result. It has been applied to a passive tag design, and is fabricated successfully based on 0.35 μ m CMOS technology.
