摘要

提出了一种用于射频能量采集和功率充电的RF- dc变换器集成电路。为了实现宽入射射频信号的变化，勾画了指导频带，自适应阻抗匹配网络被使用。所提出的射频信号到直流转换器采用0.18 μ m CMOS工艺制作。仿真结果表明，该电路在0 dBm输入功率下，负载电阻为50 k$\Omega$，负载电容为1 pF，峰值功率转换效率(PPCE)为27%，输出电压高于2 V。

An RF-DC Converter IC for Power Charging Application

RF-DC converter integrated circuits (ICs) are presented for RF energy harvesting and power charging. To achieve wide incident RF signal variations that sketch the directing frequency band, an adaptive impedance matching network is used. The proposed RF signal to DC converter is fabricated in 0.18-um CMOS process. The simulated performances present the proposed circuit achieves Peak Power Converting Efficiency (PPCE) of 27% at 0 dBm input power, across 50 k$\Omega$ load resistance and 1 pF load capacitance and can provide an output voltage of higher than 2 V.
