In this letter, a novel 1/f noise mitigation technique is presented to improve the receiver 1/f noise performance of a 670 GHz receiver. The time-domain 1/f noise corrected samples are compared with the samples obtained without the correction. The spectral-domain analysis shows that the 1/f noise mitigation method improves the receiver noise performance by 19 dB in the receiver under test. The presented 1/f noise mitigation technique can be applied to any direct-detection receiver in the terahertz frequency range.

应用于 670 GHz 接收器的新型 1/f 噪声抑制技术


在这封信中，提出了一种新颖的 1/f 噪声抑制技术，以提高 670 GHz 接收器的接收器 1/f 噪声性能。将时域 1/f 噪声校正样本与未经校正获得的样本进行比较。谱域分析表明，1/f 噪声抑制方法将被测接收机的接收机噪声性能提高了 19 dB。所提出的 1/f 噪声抑制技术可应用于太赫兹频率范围内的任何直接检测接收器。
