“…Body biasing technique has been reported as the suitable one to design variable gain LNA. Mabrouki et al, have performed automated low and high gain mode switching using digital to analog converter (DAC). The DAC has been designed to get input from the digital signal processor (DSP) of the receiver unit or the Received Signal Strength Indicator (RSSI).…”

A comparative study on recent works on low noise amplifiers (LNAs) designed to be operated at mobile communication band is performed in this article. Here, specifications of different generations of mobile communication are listed, which are considered to classify recent works on LNAs. Even though gain and noise figure (NF) are the primary parameters of LNA; other parameters like power, linearity, bandwidth, and area also get importance. Due to this, optimization techniques handpicked for all those parameters are discussed. The inverse relation between gain and NF is exploited to achieve low noise and high gain together. While increasing the gain, power consumption is increased by drain current. Each LNA is found as good in terms of gain and other parameters to satisfy the requirements. The figure of merit is opted to find the performance of each LNA, and the comparison is performed. The best parameters reported in the comparison are 31.53 dB of gain, 0.7 dB of NF, 0.03 mw of power consumption, 18.14 dBm of third-order input intercept point (IIP3), 24 GHz bandwidth and 0.0052 mm 2 of area at different frequencies and technology nodes. In this survey, as per the optimized FoM for mobile communication, crosscoupled common gate differential LNA, which was designed to be operated at 0.3 to 2.96 GHz gives better results among CMOS LNAs.

“…Noise performance of the circuit is reduced by the channel noise introduced by the CG transistor [3]. Body biasing technique reduces the power consumption at the expense of gain and NF [4]. Instead of that, current reuse technology and sub‐threshold operations are recommended to reduce the power consumption of the circuit [5, 6].…”

This study deals with the design and optimisation of two-stage complementary metal oxide semiconductor low noise amplifier (LNA) for wireless local area network (WLAN) applications. IEEE 802.11n WLAN standard provides up to 600 Mbps speed with 40 MHz channel bandwidth and high throughput. The receiver of these WLAN applications requires LNA with higher gain and minimum noise figure (NF). Elephant Herding Optimisation technique was involved for the first time to optimise the performance of the LNA. The post-layout simulation shows that a maximum gain of 26.7 dB at 2.4 GHz is achieved in the proposed design. Feedforward noise cancelation technique is involved to get a reduced NF of 1.12 dB. The first and second stages are tuned to cover the 3 dB maximum gain bandwidth of 3.2 GHz (from 1.7 to 4.4 GHz). This LNA is designed at 90 nm technology with the supply voltage of 0.5 and 1.2 V, and consumes 8.9 mW of power. Current reuse technology is used to reduce power consumption. The input and output return losses have been found to be −18 and −15 dB, respectively at the targeted 2.4 GHz frequency. Third-order input intercept point of the optimised LNA is −8.1 dBm.
