Abstract

This paper presents a CMOS full-wave switching rectifier capable of mixer operation. The proposed CMOS switching rectifier allows DC power generation and frequency conversion without a power supply. The proposed CMOS switching rectifier using a center-tapped balun produces DC power with 25% efficiency, while at the same time providing frequency up-conversion with -18.9 dB and down-conversion with -11.9 dB. The size of the chip is 0.286 mm2, and four chips are mounted on the phased-array antenna board. The board can be used as a wirelessly powered relay module, and the module can be driven without an external power supply. The measured EVM values are -27.4dB for Tx mode and -27.5dB for Rx mode with a 400-MHz 64QAM OFDMA-mode signal (5G NR, MCS 17).
一种用于5G NR无线供电中继收发器的CMOS全波开关整流器
本文提出了一种能进行混频器工作的CMOS全波开关整流器。所提出的CMOS开关整流器可以在没有电源的情况下进行直流发电和频率转换。所提出的CMOS开关整流器使用中心抽头平衡产生25%效率的直流电源,同时提供-18.9 dB的频率上变频和-11.9 dB的频率下变频。芯片尺寸为0.286 mm2,在相控阵天线板上安装了4个芯片。该板可以用作无线供电继电器模块,无需外部电源即可驱动模块。在400-MHz 64QAM ofdma模式信号(5G NR, MCS 17)下,Tx模式的EVM值为-27.4dB, Rx模式的EVM值为-27.5dB。
