摘要

本文提出并设计了一种集成了FinFET和SOI MOSFET结构的基于ge的IT-FinFET复合器件。该器件具有强大的栅极控制和高驱动电流能力,可在大范围内实现高效整流,在微波无线功率传输领域具有广阔的应用前景。考虑到复合器件结构参数变化所带来的复杂和多方面的影响,本研究纳入了多个关键器件参数,包括传输特性和开关电流比,以综合评估其对电气性能的影响。通过详细分析,确定了精馏应用的最佳结构参数。仿真结果表明,所提出的IT-FinFET在−20 dBm至42 dBm的宽输入功率范围内实现了高效整流,总范围为62 dBm。值得注意的是,与硅基MOSFET相比,61%的功率范围实现了超过30%的整流效率,将范围延长了20 dBm。此外,13 dBm的整流效率超过50%,是硅基MOSFET的三倍多。这些结果强调了所提出的IT-FinFET在广泛的输入功率水平范围内实现有效整流的能力。

Wide range rectifier using Ge-based IT-FinFET for 2.45 GHz microwave wireless power transmission
This paper proposes and designs a composite device, the Ge-based IT-FinFET, which integrates FinFET and SOI MOSFET structures. The device features strong gate control and high driving current capabilities, enabling efficient rectification over a wide range, with promising applications in the field of microwave wireless power transfer. Considering the complex and multifaceted effects caused by variations in the structural parameters of the composite device, this study incorporates multiple critical device parameters, including transfer characteristics and the on/off current ratio, to comprehensively evaluate their impact on electrical performance. The optimal structural parameters for rectification applications are determined through detailed analysis. Simulation results demonstrate that the proposed IT-FinFET achieves efficient rectification over a wide input power range from −20 dBm to 42 dBm, spanning a total range of 62 dBm. Notably, 61 % of the power range achieves rectification efficiencies exceeding 30 %, extending the range by 20 dBm compared to Si-based MOSFET. Furthermore, a range of 13 dBm achieves rectification efficiencies exceeding 50 %, over three times wider than that of Si-based MOSFET. These results underscore the capability of the proposed IT-FinFET to achieve efficient rectification across a broad range of input power levels.
