Abstract

An RF-DC power conversion system is designed in a 0.25mum CMOS technology to efficiently convert RF energy to DC voltages. The rectifier has 60% efficiency and can rectify input voltages as low as 50mV by using floating gate transistors as rectifying diodes. For distances of 15 meters, 1 volt DC is measured with 0.3muA load current at 906MHz. The system operates with 5.5muW (-22.6 dBm) received power, corresponding to 42 meters operating distance with a 4W source

无源供电传感器网络的高效远场射频功率转换系统

采用0.25 μ m CMOS技术设计了一种射频-直流功率转换系统，可有效地将射频能量转换为直流电压。采用浮栅晶体管作为整流二极管，整流效率达60%，可整流输入电压低至50mV。对于15米的距离，以0.3muA负载电流在906MHz下测量1伏直流电。系统在5.5muW (-22.6 dBm)的接收功率下工作，对应于4W源的42米工作距离
