“…The device uses an active phase shifter in the amplifier's feedback loop to change the phase of signal amplified as indicated in [17,18]. Cascode structures [19,20] can also be used to incorporate the advantages such as reduced Miller effect, large bandwidth and also noise figure can also be reduced. The reduction in power consumption using current-reused CG stage is shown in [21].…”

The propose exhibits a tunable low noise amplifier (LNA), which provides the tunability at sub-GHz frequency range and hence can become choicest frequency range for 5G applications. Common source (CS) with source degeneration inductor LNA is proposed; in which the inductor in source branch is replaced by gyrator-c active inductor which not only reduced the overall area of the circuit but can also be used to provide the feature of tunability by changing the bias voltage of CMOS based active resistor in feedback branch. Therefore, instead of having a LNA circuit for the fixed frequency, a single tunable LNA design can be used over a range of frequency from 1GHz to 5GHz. The proposed approach will provide the direct tuning to the circuit. The forward voltage gain achieved is greater than 10dB, input matching parameter is less than -10dB and the output matching parameter is less than -10dB. The average power dissipated is 0.02W. The results can be tuned by controlling the feedback voltage of tunable active inductor (Tunable_AI). The tunable results can be achieved up to the bandwidth of 1GHz.

“…Conventional wireless receivers often rely on the inductor degenerated LNA, which possesses desirable attributes [1][2][3], but within a narrow frequency band centred around a single frequency [4,5]. Alternatively, distributed amplifiers (DAs) [6][7][8][9][10][11] offer enhanced impedance matching and high gain across a broader frequency range, albeit necessitating multiple inductors. Another approach for designing broadband LNAs involves employing current conveyors (CC) [12][13][14].…”

This paper introduces a two-stage ultra-wideband low-noise amplifier (UWB-LNA) intended to be used in wireless communication systems. The architecture uses a novel double-resonance load network in the first stage and resistive shunt feedback in the second stage to achieve wide bandwidth with a flat response. A common gate stage at the input port seeks to present a high-impedance load to the single resonant network, while concurrently shunt negative feedback, source degeneration, and cascoded feedback schemes are used to improve performance. In this respect, the cascoded feedback provides flat gain across a wide bandwidth, while the source degeneration helps in impedance matching. Post-layout foot-print for the UWB-LNA designed and simulated using Cadence Virtuoso 180nm technology is0.532 mm² with an operating frequency 3.1–10.6 GHz incorporated. Operating on a 1.8 V supply voltage, it consumes 6 mW of power. The amplifier achieves a maximum gain of 18.75 dB, maintaining a flat low noise figure of 3.15 dB across frequencies ranging from 3.1 to 10.6 GHz. Stability analysis using the Roulettes test confirms the reliability of the proposed LNA, with Kf > 1 and Δ < 1.
