This paper presents a 280 GHz amplifier design strategy for a robust multistage amplifier in a sub-Terahertz (sub-THz) regime in 130 nm SiGe technology. The presented 280 GHz amplifier consists of 14 stages of the cascaded common emitter (CE) amplifier which offers a compact and improved-noise design due to the absence of the area-expensive and lossy baluns at such high frequencies. The interstage-matching network was flexibly constructed with two separate resonant tanks using metal–insulator–metal (MIM) capacitors and microstrip transmission lines (MSTLs) between each stage. The measured amplifier achieved a peak power gain of 10.9 dB at 283 GHz and a 3 dB gain of bandwidth of 30 GHz between 270 and 300 GHz. The peak output power of the amplifier was 0.8 dBm with an output of 1 dB gain compression point (OP1dB) of -3.6 dBm in simulation. The 14-stage amplifier consumes an area of 0.213 mm², including all the pads. With the proposed interstage matching approach, a well-balanced 280 GHz amplifier has been demonstrated. The proposed design strategy is widely applicable to sub-THz receivers for future wireless communication systems.

采用 130 nm SiGe 技术的灵活级间匹配策略的 280 GHz 30GHz 带宽级联放大器

本文介绍了一种 280 GHz 放大器设计策略，用于在 130 nm SiGe 技术中实现亚太赫兹 (sub-THz) 范围内的稳健多级放大器。所展示的 280 GHz 放大器由 14 级级联共发射极 (CE) 放大器组成，由于在如此高的频率下不存在面积昂贵且有损耗的巴伦，因此该放大器提供了紧凑且改进的噪声设计。级间匹配网络由两个独立的谐振回路灵活构建，在每个级之间使用金属-绝缘体-金属 (MIM) 电容器和微带传输线 (MSTL)。测量的放大器在 283 GHz 处实现了 10.9 dB 的峰值功率增益，在 270 和 300 GHz 之间实现了 30 GHz 的 3 dB 带宽增益。在模拟中，放大器的峰值输出功率为 0.8 dBm，1 dB 增益压缩点 (OP1dB) 的输出为 -3.6 dBm。²、包括所有的焊盘。使用所提出的级间匹配方法，已经证明了一个平衡良好的 280 GHz 放大器。所提出的设计策略广泛适用于未来无线通信系统的亚太赫兹接收器。
