在过去的几年中，无线功率传输已经被显著地研究用于植入式生物医学设备。由于极端的功率限制，植入式设备需要高效的AC-DC电源整流。本文提出了一种用于宽带无线电能传输系统的低功耗整流器。10级整流器采用标准130 nm BiCMOS工艺设计。所提出的设计可以整流低至100 mV的电压，这是传统整流器无法整流的低电压。该整流器具有较宽的工作频率范围10 kHz - 100 MHz相比，以前的作品，其中最大工作频率高达40-50 MHz。所设计的整流器能够在100 mV 7.25 MHz输入信号下实现51%的功率转换效率，这使得它非常适用于植入式传感器的无线功率传输应用。
Wireless power transfer has been studied significantly in the past couple of years for implanted biomedical devices. Due to the extreme power constraints, implantable devices need efficient AC-DC power rectification. This paper presents a low-power rectifier for a wideband wireless power transfer system. The 10-stage rectifier is designed using a standard 130 nm BiCMOS process. The proposed design can rectify voltages as low as 100 mV, which is a low voltage that traditional rectifiers are not able to rectify. The rectifier has a wider frequency operation range of 10 kHz – 100 MHz compared to the previous works where the maximum operating frequency is up to 40–50 MHz. The designed rectifier is able to achieve a power conversion efficiency of 51% with 100 mV 7.25 MHz input signal, which make it highly applicable for the wireless power transfer applications for implantable sensors.
