Abstract

This work reports an ultra-low noise, multi-stage stagger-tuned low-noise amplifier (MS-ST-LNA) over the D-band performance and achieves a best trade-off between noise, bandwidth, and gain parameters. The ultra-low-noise is achieved in three ways: First, the high-gain 3-stage stagger tuned amplifier (STA) realizes a 3X gain compared to the conventional single-stage amplifier, which sets a low floor noise. Second, the stagger-tuned amplifier achieves 1.6 times lower noise than the traditional single-stage amplifier. Finally, the stagger tune realizes a high-order transfer function, which mitigates the high-frequency noise. The full LNA is implemented and fabricated using a commercial nano-manufacturing 9-nm graphene film FET on a silicon wafer using a 0.065-μm commercial process, occupying an area of 0.21 mm2. The proposed design achieves an optimum performance: a maximum measured gain of 20.5 dB and a minimum noise figure (NF) of 4.2 dB over 123.7 to 162.5 GHz. The proposed LNA consumes ultra-low power consumption of 21.3 mW under the power supply of 1.2 V.

采用多级交错调谐方法的新型石墨烯工艺低噪声放大器在 D 波段上的性能分析
这项工作报告了一种超低噪声、多级交错调谐低噪声放大器(MS-ST-LNA)的 D 波段性能,并在噪声、带宽和增益参数之间实现了最佳权衡。超低噪声通过三种方式实现:首先,与传统的单级放大器相比,高增益三级交错调谐放大器(STA)实现了 3 倍的增益,从而实现了低本底噪声。其次,交错调谐放大器的噪声比传统单级放大器低 1.6 倍。最后,交错调谐实现了高阶传递函数,从而降低了高频噪声。全 LNA 采用商业纳米制造的 9 纳米石墨烯薄膜场效应晶体管在硅晶片上以 0.065μm 的商业工艺实现和制造,占地面积为 0.21 平方毫米。拟议的设计实现了最佳性能:在 123.7 至 162.5 GHz 范围内,最大测量增益为 20.5 dB,最小噪声系数 (NF) 为 4.2 dB。在 1.2 V 的电源电压下,拟议的 LNA 消耗 21.3 mW 的超低功耗。

期刊介绍: The Journal of Infrared, Millimeter, and Terahertz Waves offers a peer-reviewed platform for the rapid dissemination of original, high-quality research in the frequency window from 30 GHz to 30 THz. The topics covered include: sources, detectors, and other devices; systems, spectroscopy, sensing, interaction between electromagnetic waves and matter, applications, metrology, and communications. Purely numerical work, especially with commercial software packages, will be published only in very exceptional cases. The same applies to manuscripts describing only algorithms (e.g. pattern recognition algorithms). Manuscripts submitted to the Journal should discuss a significant advancement to the field of infrared, millimeter, and terahertz waves.
