“…Although this is a simple method for receiving multiple frequency bands simultaneously, the receiver sensitivity can be degraded due to the presence of unwanted signals in the wide frequency band. The most effective technique to achieve DB-LNA is to insert the notch filters in a wideband LNA [15][16][17][18][19][20]. Compared to the switchable LNAs, in this approach, the LNA supports simultaneous dual-band operations and consumes lower power.…”

In this paper, a two-stage concurrent dual-band low noise amplifier (DB-LNA) operating at 2.4/5.2-GHz is presented for Wireless Local Area Network (WLAN) applications. The current-reused structure using resistive shunt-shunt feedback is employed to reduce power dissipation and achieve a wide frequency band from low frequency to-5.5-GHz in the inverter-based LNA. The second inverter-based stage is employed to increase the gain and obtain a flat gain over the frequency band. An LC network is also inserted at the proposed circuit output to shape the dual-band frequency response. The proposed concurrent DB-LNA is designed for RF-TSMC 0.18-μm CMOS technology, which consumes 10.8 mW from a power supply of 1.5 V. The simulation results show that the proposed DB-LNA achieves a direct power gain (S 21) of 13.7/14.1 dB, a noise figure (NF) of 4.2/4.6 dB, and an input return loss (S 11) of −12.9/−14.6 dBm at the 2.4/5.2-GHz bands.

This article presents the differential CMOS-LNA design for wireless receiver at the frequency of 3.4GHz. This differential 𝑳𝑵𝑨 provides less noise figure (NF), high gain and good reverse isolation as well as good stability. The designed LNA is simulated with a 180 nanometers CMOS process in cadence virtuoso tool and simulate the results by using SpectreRF simulator. This LNA exhibits a NF of 0.7dB, a high voltage gain of 28dB, and good reverse isolation (S12) of -70dB. It produces an input and output reflection coefficient (S11) of - 6.5dB and (S22) of -14dB, and it maintains good stability of Rollet factor Kf > 1, and also alternate stability factor B1f < 1, respectively.

“…The input reflection coefficient ( is -23.847 dB, output reflection coefficient ( is -17.479 dB, contrary isolation ( is -20.458 dB and stability factor is 1.425. The consumption of power is lower with a voltage source of 1.2 V and the recommended LNA used in wireless and satellite communication applications.Khosravi et al[40] developed a 2.4/5.2 GHz of LNA with parallel twofold-band, which can be used by Advanced Designed System (ADS) for WLAN applications using R.F-TSMC 0.18 μm CMOS technology. The authors chose to apply LNA wideband and notch filters to employ the current-reused method to decrease energy usage and offer flat gain across a wide bandwidth.…”

The low noise amplifier (LNA) circuit is exceptionally imperative as it promotes and initializes general execution performance and quality of the mobile communication system. LNA's design in radio frequency (R.F.) circuit requires the trade-off numerous imperative features' including gain, noise figure (N.F.), bandwidth, stability, sensitivity, power consumption, and complexity. Improvements to the LNA's overall performance should be made to fulfil the worldwide interoperability for microwave access (WiMAX) specifications' prerequisites. The development of front-end receiver, particularly the LNA, is genuinely pivotal for long-distance communications up to 50 km for a particular system with particular requirements. The LNA architecture has recently been designed to concentrate on a single transistor, cascode, or cascade constrained in gain, bandwidth, and noise figure.
