“…In this work the stability of the design is checked by achieving a stable gain and s-parameters over the required frequency range. The device performance is also dependent on the transistor dimensions and the package type as shown in figure 2 [8]. So, these should also be considered while design implementation.…”

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.

The integration of wireless communication, e.g., in real- or quasi-real-time applications, is related to many challenges such as energy consumption, communication range, quality of service, and reliability. The improvement of wireless sensor networks (WSN) performance starts by enhancing the capabilities of each sensor node. To minimize latencies without increasing energy consumption, wake-up receiver (WuRx) nodes have been introduced in recent works since they can be always-on or power-gated with short latencies by a power consumption in the range of some microwatts. Compared to standard receiver technologies, they are usually characterized by drawbacks in terms of sensitivity. To overcome the limitation of the sensitivity of WuRxs, a design of a low noise amplifier (LNA) with several design specifications is required. The challenging task of the LNA design is to provide equitable trade-off performances such as gain, power consumption, the noise figure, stability, linearity, and impedance matching. The design of fast settling LNA for a duty-cycled WuRx front-end operating at a 868 MHz frequency band is investigated in this work. The paper details the trade-offs between design challenges and illustrates practical considerations for the simulation and implementation of a radio frequency (RF) circuit. The implemented LNA competes with many commercialized designs where it reaches single-stage 12 dB gain at a 1.8 V voltage supply and consumes only a 1.6 mA current. The obtained results could be made tunable by working with off-the-shelf components for different wake-up based application exigencies.
