There are no external components, except for the antenna. The passive IC＇s power supply is taken from the energy of the received RF electromagnetic field with the help of a Schottky diode rectifier. The RFID analog front end includes a local oscillator, clock generator, power on reset circuit, matching network and backscatter,rectifier,regulator, and AM demodulator. The IC, whose reading distance is more than 3m,is fabricated with a Chartered 0.35μm two-poly four-metal CMOS process with Schottky diodes and is EEPROM supported. The core size is 300μm × 720μm.展开更多

This platform efficiently reduces the design and development time and cost, and implements a fast prototype design of the passive UHF RFID tag. It includes the RFID analog front end and the tag control logic, which is implemented in an Altera ACEX FPGA. The RFID analog front end, which is fabricated using a Chartered 0.35μm two-poly four-metal CMOS process, contains a local oscillator, power on reset circuit, matching network and backscatter, rectifier, regu- lator,AM demodulator, etc. The platform achieves rapid, flexible and efficient verification and development, and can also be fit for other RFID standards after changing the tag control logic in FPGA.展开更多

The application of Intemet of things make its and related enterprises in the supply chain synchronization integration in the process, timely access to relevant information, understand the real needs of the market, the effective control of each link of the supply chain inventory quantity and effectively reduce the supply chain inventory and capital takes up between cooperative enterprises. Thus, in effectively improve the efficiency of the original system at the same time also save the cost of the supply chain management. With the combination of the RFID technique, we finalize the implementation of the logistics information and automation, automatic identification and inspection of finished goods inspection, greatly reduce the human capital, simplify the acceptance of goods and reduce the cost of handling times and human factors caused losses. In the final part, we conclude the work and propose our prospect.展开更多
