A 30-60 GHz 90-nm CMOS Low Noise Amplifier with optimum NF for Radio Astronomy Receivers

Finding faint radio signals from far-off astronomical sources is essential to radio astronomy because it helps us learn more about the universe. In order to maximize the amount of noise reduced throughout the amplification process, Low Noise Amplifiers (LNA), are essential for boosting these weak signals. The LNA topology comprises a common gate for input impedance matching, a common drain for output impedance matching and an active feedback network configuration that minimizes noise. The LNA operates throughout the whole Q-band frequency range of 30–60 GHz and is built utilizing 90nm CMOS technology. The gadget maintains an average noise figure of 0.06 dB and reaches a minimal NF of 0.1 dB In addition; it uses 13mW of dc power and gives a peak power gain of 42 dB. In the end, this approach helps radio astronomers uncover new celestial occurrences by developing more efficient communication networks.
