NFC Application Oriented Design Of Digital Baseband Of Low Power Electronic Tag

Electronic Tag, i.e., RFID (Radio Frequency Identification), is a kind of technology which conducts communication target recognition and non-contact data exchange using electromagnetic coupling. Along with the rapid expansion of the Internet of Things (IoT), and the promotion of NFC application, RFID technology has developed favorably, and will continue to be widely used.In this thesis, I study and design a NFC application oriented digital baseband of electronic Tag Chip. The IP core of the tag chip which is designed independently will be used in terms of the research and development on the application layer, and applied in the Chinese financial integrated circuit chip card, it can also provide design support for NFC technology to be compatible with ISO 14443-B. This design is based on the Radio Frequency power and signal interface (14443-2) and the Initialization and anti-collision(14443-3) of the ISO/IEC 14443-B protocol, and the interface for data transmission between the IP and the User Logic is added in the design.First of all, the system architecture of the digital baseband of the RFID tag chip and each module of the baseband have been designed according to the design objective, using the top-down design method. And then, the bottom-up method has been adopted to simulate the design to validate the function of the whole system. Besides, due to NFC’s harsh requirement of the power consumption, low power design has been done to meet the requirements,78.4% of power consumption has been optimized. The final simulation and test results prove that the design is consistent with the functional requirements and the expected performance indicators.
