A High Performance 60-90 GHz 90-nm CMOS Low Noise Amplifier for Radio Astronomy Receivers

Recording faint radio signals from distant astronomical sources is important for the development of radio astronomy, providing deeper understanding of the universe. Low Noise Amplifiers (LNAs) amplify faint signals with minimal introduction of noise. The suggested LNA design provides input impedance matching through a common-gate topology and output impedance matching through a commondrain topology, with an active feedback network for noise reduction. This LNA has an operating frequency range of the entire E-band from 60–90 GHz and is realized on 90nm CMOS technology. It has an average NF of 1 dB and a maximum power gain of 38 dB. It consumes a minimum of 18mW while providing efficient operation with minimal energy consumption, addressing a new way to detect weak signals.
