“…The variation in the signal to noise ratio (SNR) variation has been suggested to be created due to radio frequency (RF) signal chain component and that variation is measured by NF and noise factor (F) [14], [15]. In case of NF and F, the minimum value is indicated to better performance because such specifications specify the amplifier or radio receiver presentation and capability [16]- [20].…”

<p class="Abstract"><span>The demand of low noise amplifier (LNA) has been rising in today’s communication system. LNA is the basic building circuit of the receiver section satellite. The design concept demonstrates the design trade off with NF, gain, power consumption. This paper reports on with analysis of wideband LNA. This paper shows the schematic of LNA by using Darlington pair amplifier. This LNA has been fabricated on 90nm CMOS process. This paper is focused on to make comparison of three stage and single stage LNA. Here, the phase mismatch between these patameters is quantitavely analyzed to study the effect on gain and noise figure (NF). In this paper, single stage LNA has shown the 23 dB measured gain, while the three stages LNA has demonstrated 29 dB measured gain. Here, LNA designed using darlington pair shows low NF of 3.3-4.8 dB, which comparable to other reported single stage LNA designs and appreciably low compared to the three stages LNA. Hence, findings from this paper suggest the use of single stage LNA designed using Darlington pair in transceiver satellite applications.</span></p>

“…On-chip transformers are more and more widely used in the mm-wave circuits design. They can be used as the input/output balun, the inter-stage matching network [18], magnetically feedback [19], power splitter or combiner [8] and so on. The coupling between the primary and secondary coils provides an extra design freedom without increasing the chip area consumption.…”

This paper presents a multiband reconfigurable low noise amplifier (LNA) based on dual-feedback common-gate (CG) configuration. The input impedance of the LNA is tuned synchronously with output load due to the reflection of load impedance to input by the proposed source-follower positive feedback method. This method also improves the stability of the LNA, which is an issue in conventional positive feedback methods. In addition, both the source-follower positive feedback and the negative feedback by capacitor cross-coupling help to reduce noise figure. Fabricated in TSMC 0.18 µm CMOS process, measurement results show the LNA is reconfigurable from 1.833 GHz to 2.47 GHz, with S11 automatically centered with S21. It achieves a power gain from 15 to 17.4 dB, 1.62 dB minimum NF, and −4.4 dBm maximum IIP3. 10.5 mA current is consumed from 1.8 V supply.
