Today, according to the research status at home and abroad, oprfid intelligent will share with you some technical development trends of RFID Tag Manufacturer, and put forward the basic countermeasures for the application and development of electronic tags at this stage in our country. Chip technology is a core technology of RFID technology. A tag chip is a system, which integrates all circuits except tag antenna and matching line, including RF front-end, analog front-end, digital baseband, memory unit and other modules. The basic requirements for chips are light, thin, small, low and cheap.
In foreign countries, Ti, Intel, Philips, STMicroelectronics, Infineon, NXP, ATMEL and other integrated circuit manufacturers have made outstanding achievements in developing RFID chips with small volume, low power consumption and low price. For example, the minimum RF input power of UHF Passive Tag developed by ATMEL company can be as low as 16.7 μ W。 The Swiss Federal Institute of technology has designed a model with a minimum input power of only 2.7 μ W. 2.45 GB label chip with a reading and writing distance of 12 M.

Therefore, the development trend of RFID chip design and manufacturing technology is that the chip power consumption is lower, the action distance is longer, the reading and writing speed is faster, the reliability is higher, and the cost is continuously reduced. In addition to increasing the storage capacity of tags to carry more information, reducing the size of tags to reduce costs, and improving the sensitivity of tags to increase the reading distance, the current research hotspots also include: ultra-low power circuits; Security and privacy technology, password function and implementation; Low cost chip design and manufacturing technology; New storage technology; Anti conflict algorithm and implementation technology; Integration technology with usb rfid reader writer; An overall solution closely integrated with the application system.
