Digital Circuit Design Of Sensing And Identification Integration Tag Chip Based On ISO18000-6C Standard

RFID is an innovative technology which can identify objects quickly. With manyadvantages such as fast speed, strong anti-interference ability and repeatable readingand writing features, it has been widely used in customs, anti-counterfeiting, military,product manufacturing, access control and many other fields. The technology canextend the field application when it combines with the temperature sensor and statuschange counter. As the cornerstone of the Internet of Tings, RFID attract more attentionof many countries. As China is becoming a big country in IOT, RFID technology israpidly development, but we still have a gap in key technologies of UHF fields withdeveloped countries. Therefore, it has a great significance for the research of UHFRFID and other related technology.This paper design a tag chip in UHF which can achieve ISO/IEC18000-6Cprotocol, temperature sensing function and the counting of switch state changes. First, itintroduces the application status and the prospects of the IOT and RFID science andanalysis the ISO/IEC18000-6C protocol. Second, for the specific application of theelectronic tags, it describes the key technologies such as design of low-power of digitalbaseband, memory initialization and continuous back link frequency of label. Then thetechnical specifications and system architecture of the digital baseband are proposed,the analysis and description of the design ideas and simulation results are given.Followed, EDA tools are used to achieve logic synthesis and physical implementation.Finally, the result of power consumption in baseband is given and it shows the circuitconsumes4μW.
