资料介绍
文章分析了射频电子标签芯片电源的特点,根据电源低电压和低成本要求,讨论了传统的带隙基准源和全CMOS的基准电压源电路方案,设计并实现了一种适合电子标签芯片应用的全CMOS的基准电压源电路。该电路采用SMIC 0.18μm标准CMOS工艺实现,电源电压范围为1~5 V,电源敏感度为1~3%/V,输出电压的温度特性为3~20.7 ppm/℃,符合射频电子标签的设计要求。
The specifications of low power supply voltage and low cost in RFID transponder were analyzed in this paper. And the traditional bandgap and full CMOS reference voltage circuit were discussed. A full CMOS reference voltage circuit was designed and implemented suitable for transponder. The circuit was implemented in SMIC 0. 18 μm standard CMOS process. The power supply range is from 1 to 5 V,and the supply sensitivity is from 1 to 3 % /V,the output reference voltage temperature dependent is from 3 to 20. 7ppm /℃. The design requirements of RFID transponder are fulfilled.
