Iso18000-6c Standard Uhf Rfid Tag Chip Digital Integrated Circuit Design

RFID (Radio Frequency Identification) has been widely used in many areas including access control, animal identification, postal logistics, automatic highway toll, supply chain management as well as product tracing etc. With its great deal of significant features such as contactless, flexibility, high security and reliability, RFID is becoming the most prominent technology in auto-id applications. Benefit from the development of RTLS,WSN and the Internet of Things, the UHF RFID is becoming the most prominent and prospected technology in RFID applications. In China, the market for UHF RFID is growing rapidly, however, there is not much study and research on UHF RFID, especially for the tag chip Therefore, the designing of the baseband processor for the UHF RFID tag is becoming increasingly critical.In this thesis, we first describe the current state and prospect of RFID technology. Then we introduce the basic principle of RFID technology, most focus on the UHF RFID systems and their corresponding internal standards. Since the low-power design is the main objective in designing a UHF RFID tag baseband processor, we analyzes the mechanism of the power consumption in CMOS integrated circuit and describe some low power design approaches which can be used in deep sub-micron CMOS process. Finally, we propose a UHF RFID tag baseband processor which is compliant with ISO18000-6C protocol. Each module in the architecture has been designed and simulated. The whole chip has been implemented and fabricated successfully in TSMC 0.18μm CMOS Mixed Signal Process. Test results show that the baseband processor fulfills the ISO18000-6C protocol and performs very well when communicated with RFID reader.
