Abstract: Radio frequency identification technology is an indispensable part of building the Internet of Things ecosystem. The low cost and performance optimization of electronic tag chips directly determine the depth of application for this technology across numerous scenarios. The functionality, power consumption, and area of the digital baseband are precisely the focal points in electronic tag chip design. This paper completes a digital baseband design of ultra-high-frequency electronic tag chip based on the international standard ISO/IEC 18000-6C protocol, integrates temperature sensing functionality, and features low power consumption and small area. The functional verification results meet expectations, and after logic synthesis and power analysis, the digital baseband power consumption is 60.96 μW, and the area is 0.032 mm², which meets the design requirements.
