摘要

用28nm全耗尽绝缘体上硅（FDSOI）CMOS工艺演示了一种宽带共栅（CG）级联低噪声放大器（LNA）。宽带宽是通过第一级中的CG结构和紧密耦合（$k=0.86$）传输线变压器（TLT）匹配网络实现的。具有交叉耦合电容器的gm升压技术提高了CG放大器的增益和噪声系数（NF）。高输入1-dB增益压缩点（IP1dB）可以通过在第二级级联放大器处引入级间电感器来实现。LNA的增益为19.3 dB，NF为3.1 dB，带宽为19.8 GHz（63%），28 GHz时为-15.7 dBm IP1 dB。

A 21–41-GHz Common-Gate LNA With TLT Matching Networks in 28-nm FDSOI CMOS

A wideband common-gate (CG) cascode low-noise amplifier (LNA) is demonstrated with a 28-nm fully depleted silicon on insulator (FDSOI) CMOS process. Wide bandwidth is achieved with a CG structure in the first stage and tightly coupled ( $k=0.86$ ) transmission line transformer (TLT) matching networks. A gm-boosting technique with cross-coupled capacitors improves the gain and noise figure (NF) of the CG amplifier. A high-input 1-dB gain compression point (IP1 dB) can be achieved by introducing an inter-stage inductor at the second-stage cascode amplifier. The LNA shows 19.3 dB gain, 3.1 dB NF, 19.8 GHz (63%) of 3 dB bandwidth, and −15.7 dBm IP1 dB at 28 GHz.

期刊介绍： The IEEE Microwave and Wireless Components Letters (MWCL) publishes four-page papers (3 pages of text + up to 1 page of references) that focus on microwave theory, techniques and applications as they relate to components, devices, circuits, biological effects, and systems involving the generation, modulation, demodulation, control, transmission, and detection of microwave signals. This includes scientific, technical, medical and industrial activities. Microwave theory and techniques relates to electromagnetic waves in the frequency range of a few MHz and a THz; other spectral regions and wave types are included within the scope of the MWCL whenever basic microwave theory and techniques can yield useful results. Generally, this occurs in the theory of wave propagation in structures with dimensions comparable to a wavelength, and in the related techniques for analysis and design.
