Abstract

In this brief, a current-reused noise-canceling low noise amplifier (LNA) operating at 60-GHz is proposed. To reduce the noise of cascode at millimeter-wave (mm-wave) frequency, an auxiliary path is introduced to neutralize the extra thermal noise of common-gate (CG) transistor caused by parasitic capacitance. The noise-canceling path is implemented in a current-reused way to prevent an excessive rise in dc power consumption. A size-aggregated self-coupling-canceling transformer is developed to decrease chip area without compromising noise cancellation effectiveness. The proposed cascode noise-canceling LNA is fabricated in a conventional 40-nm CMOS technology. The measurement results show a peak gain of 16.8 dB at 53.6 GHz and a 3-dB bandwidth from 50.6 to 67 GHz. The measured typical noise figure (NF) is 4.4–6.3 dB within the operating frequency range. The in-band input 1-dB compression point (IP1dB) is −13.0 dBm at 60 GHz. The proposed LNA can support 64-QAM with a 500-MHz channel bandwidth at 60 GHz achieving 2.3% Error Vector Magnitude (EVM).

60-GHz 电流回用级联降噪低噪声放大器

本文提出了一种工作频率为 60 千兆赫的电流复用噪声消除低噪声放大器（LNA）。为降低毫米波（mm-wave）频率下的级联噪声，引入了一条辅助路径，以中和共栅晶体管（CG）因寄生电容而产生的额外热噪声。噪声消除路径以电流重复使用的方式实现，以防止直流功耗过度上升。为了在不影响噪声消除效果的情况下减少芯片面积，开发了一种尺寸聚合型自耦合噪声消除变压器。所提出的级联消噪 LNA 采用传统的 40 纳米 CMOS 技术制造。测量结果表明，53.6 GHz 时的峰值增益为 16.8 dB，带宽为 3 dB（50.6 至 67 GHz）。在工作频率范围内，测得的典型噪声系数（NF）为 4.4-6.3 dB。带内输入 1 dB 压缩点 (IP1dB) 在 60 GHz 时为 -13.0 dBm。拟议的 LNA 可在 60 GHz 频率下支持具有 500 MHz 信道带宽的 64-QAM，达到 2.3% 的误差矢量幅度 (EVM)。
