“…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 frequency ranges from 1 GHz −5 GHz can also be used for the blue-tooth applications and the results are given in [22].…”

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.
