Abstract

In this paper, we present 13.56 MHz high-efficiency power transmitter and power receiver for wirelessly powered biomedical implants. The power transmitter is designed using class-E PA and the power receiver is designed using controllable rectifier and current-mode PWM buck converter. At $V_{\mathrm{DD}} = 3.3$ V, the output power and PAE of class-E PA are 26.7 dBm and 91.5% respectively. The controllable rectifier yields maximum PCE and VCE of 89.6% and 83.9% at 1 kΩ respectively. The efficiency of current-mode PWM buck converter at a switching frequency of 3 MHz with a loading current of 150 mA is 93.4%.

13.56 MHz高效功率发射器和接收器，用于无线供电生物医学植入物

在本文中，我们提出了13.56 MHz的高效功率发射器和功率接收器，用于无线供电的生物医学植入物。功率发射器采用e类PA设计，功率接收器采用可控整流器和电流型PWM降压变换器设计。在$V_{\mathrm{DD}} = 3.3$ V时，e类PA的输出功率为26.7 dBm, PAE为91.5%。可控整流器在1 kΩ时PCE和VCE分别达到89.6%和83.9%。在开关频率为3 MHz、负载电流为150 mA时，电流型PWM降压变换器的效率为93.4%。
