摘　　要：为了提高稳压器的性能,通过对一级分流稳压电路的研究,提出了一种新型的,可以用于超高频射频标签中的两级分流稳压电路.该电路在0.18μm的CMOS工艺下实现,在正常工作电压下功耗低(6.7μW左右),在高输入功率下能有效泄放大电流稳定电压.同时,该电路具有结构简单、占用面积小、稳定性好等优点.In order to enhance the performance of the regulator circuit, through the analysis of one stage shunt regulator circuit, this paper proposes a new type of two stage regulator circuit, which can be used in UHF RFID tag. The circuit in a 0.18μm analog CMOS technology, achieves characters of low power consumption （6.7μW） in the work period, and relieving large current effectively with high input power in order to possess a stable voltage. Meanwhile, the circuit is simple in structure,occupies a small area, and has good stability.
