摘　　要：电子标签是创新消费模式、提升生活质量和工作效率的热门新科技,但是由于功耗和成本的原因阻碍了其广泛应用。介绍了一种电子标签芯片电源产生电路的优化设计,探讨了限幅电路、整流电路、模拟电源电路、数字电源电路和EEPROM高压电路的低功耗设计技术和实现方法,提出了融合并联分流的限幅电路、改进的桥式整流电路、带有低压检测复位功能的模拟电源电路。低功耗电源产生电路已成功应用到无源电子标签芯片的设计中,并在SMIC 0.35μmCMOS工艺下流片成功。Introduces are some optimized designs of power supply circuit for passive RFID transponder. Many low power design technologies and realization methods are addressed, such as amplitude limiter, rectifier circuits, analog power circuit, digital power circuit and high voltage circuit. The amplitude limiter circuit based on current distributaries by parallel connection method and the optimized bridge rectifier circuit and the analog power circuit with low voltage checking and reset are proposed. It is applied to a passive tag design, and is fabricated successfully based on SMIC 0.35 μm CMOS technology.
