Abstract

A magnetoelectric antenna (ME) is a miniaturized device that exhibits the dual capability of energy harvesting and sensing in different frequency bands. In this paper, a behavioral circuit model for the ME antenna is presented to capture the radio frequency (RF) energy harvesting operation during circuit simulations. The ME antenna design of this work is under development for wireless communication with implantable devices, where one role of the antenna is to receive pulse-modulated power from a nearby transmitter. In this application, the proposed behavioral ME antenna model can be utilized during design optimizations of the energy harvesting circuits. The model has been assessed through simulations with an energy harvester design in 65nm CMOS technology. Measurements were performed to validate the results of the wireless power transfer link with an ME antenna having a 2.57 GHz resonance frequency connected to an energy harvester chip.

磁电天线能量收集电路的仿真与实验评估

磁电天线是一种在不同频段具有能量收集和传感双重能力的小型化器件。本文提出了一种行为电路模型，用于在电路仿真过程中捕捉射频能量收集操作。这项工作的ME天线设计正在开发中，用于与植入式设备进行无线通信，其中天线的一个作用是接收来自附近发射器的脉冲调制功率。在此应用中，所提出的行为ME天线模型可用于能量收集电路的设计优化。该模型已通过65纳米CMOS技术的能量采集器设计进行了仿真评估。通过测量验证无线电力传输链路的结果，将具有2.57 GHz谐振频率的ME天线连接到能量采集器芯片上。
