摘要

提出了一种新型二极管连接MOS晶体管的超高频微功率整流器的设计策略和效率优化。所提出的二极管连接MOS晶体管采用了一种新的体连接方式，与传统的二极管连接晶体管相比，降低了阈值电压和漏电流。在典型整流器中使用所提出的二极管可以显著改善输出电压和电流，因此与使用传统二极管的相同整流器结构相比，效率提高了。提出了效率优化的设计步骤，并采用叠加法优化多输出整流器的性能。最后根据所提出的优化方法设计了一个五级双输出整流器。仿真结果验证了该方法在效率和面积上的改进。所有电路都采用标准的0.18um CMOS技术设计。

A UHF micro-power CMOS rectifier using a novel diode connected CMOS transistor for micro-sensor and RFID applications

The design strategy and efficiency optimization of UHF micro-power rectifiers using a novel diode connected MOS transistor is presented. The proposed diode connected MOS transistor uses a new bulk connection which leads to reduce the threshold voltage and leakage current in compare to conventional diode connected transistors. Using the proposed diode in typical rectifiers makes a significant improvement in output voltage and current therefore the efficiency is increased comparing to the same rectifier architectures using conventional diodes. Also a design procedure for efficiency optimization is presented and a superposition method is used to optimize the performance of multiple output rectifiers. Finally a five stage double output rectifier is designed based on the proposed optimization method. Simulation results verified the improvement in efficiency and area. All circuits are designed in a standard 0.18um CMOS Technology.
