  • 整流器件是微波无线能量传输系统的核心部分, 新型整流器件的研发是当前领域研究的重要方向. 肖特基二极管和场效应晶体管是目前主流整流器件, 但二者整流范围有限, 无法实现兼顾弱能量和中等能量密度的宽范围整流. 有鉴于此, 本文提出并设计了2.45 GHz微波无线能量传输用Ge基p型单端肖特基势垒场效应晶体管(源端为肖特基接触, 漏端为标准p+掺杂). 在此基础上, 充分利用器件的肖特基结构, 采用新型二极管连接方式, 以实现不同偏压下开启的沟道和源衬肖特基结构的双通道宽范围整流. 采用Silvaco TCAD软件进行仿真, 对于负载为0.3 pF和70 kΩ的半波整流电路, 实现了–20—24 dBm宽范围整流, 相比同条件下Ge场效应晶体管范围拓宽8 dBm, 且在范围内整体整流效率较高, 在16 dBm整流效率峰值可达57.27%. 在–10 dBm弱能量密度的整流效率达到6.17%, 是同等条件下Ge 场效应晶体管的7倍多.
    Rectifier component is a core part of a microwave wireless energy transmission system, and the development of new rectifier components is an important research direction in this field. Schottky diodes and field-effect transistors are currently the mainstream rectifier devices, but they have a limited rectification range and cannot achieve a wide-range rectification of both weak energy and medium energy density at the same time. In view of this, in this work proposed and designed is a Ge based p-type single-ended Schottky barrier field effect transistor (Schottky contact at the source and standard p+ doping at the drain) for 2.45 GHz microwave wireless energy transmission. Based on this, the Schottky structure of the device is fully utilised and a new diode connection is used in order to realize a dual channel wide range rectification of the trench and source lined Schottky structure opened at different bias voltages. Simulations are carried out by using the Silvaco TCAD software. For a half-wave rectifier circuit with a load of 0.3 pF and 70 kΩ, a wide range from –20 to 24 dBm rectification is achieved, which is 8 dBm wider than the range of Ge field-effect transistors under the same conditions, and the overall rectification efficiency is higher in the range, with a peak rectification efficiency of 57.27% at 16 dBm. The rectification efficiency at –10 dBm weak energy density reaches 6.17%, which is more than 7 times that of Ge FETs under the same conditions.
