摘要 提出了一种适用于ISO/IEC 18000-6C标准的无源RFID(射频识别)应答器的改进电荷泵。该设计基于导通角的概念分析能量转化效率。整个结构包含主电荷泵和偏置电路,通过二极管连接的MOS管抑制负载来提升偏置电压,并调节偏置电压有效抑制反向漏电流,消除了传统电荷泵中的阈值损失。该电荷泵采用0.35μm CMOS工艺流片,实测结果表明,在距离读写器4.2 m处,负载电阻100 kΩ情况下,电荷泵输出可以达到1.5 V,能量转换效率最高可达26.2%,满足RFID系统设计要求。 An improved charge pump for ISO/IEC 18000-6C compliant passive UHF RFID transponders is presented.The power conversion efficiency（PCE） is analyzed based on conduction angle.The structure consists of a main charge pump and a bias circuit.The load of bias circuit is suppressed to raise the bias voltage by introducing diode-connected MOSFET,the reverse leakage current is suppressed and the threshold voltage drop is eliminated with the help of the bias structure.The charge pump has been fabricated with 0.35 μm CMOS process,its experimental measurement shows that dc output of the charge pump is up to 1.5 V with 100 kΩ load,4.2 m away from the reader and the PCE up to 26.2% is achieved.The design meets the specification of RFID system.
