A pole-converging X-band low-noise amplifier (LNA) using 130 nm CMOS technology is proposed. An on-chip pole-converging capacitor C PC is added between the gate and drain node of the common-gate (CG) stage. The capacitor C PC combines with a noisereducing inductor L 1 to converge poles into the desired band, which results in a poleconverging effect and wideband performance. The proposed modified broadband simultaneous noise and input-matching technique is adopted in triple-cascode configuration to realize good input matching and a low noise figure (NF). Measurement results exhibit a flat maximum power gain of 17.6 dB from 8 to 12 GHz and a reverse isolation over 60 dB within the desired bandwidth along with an NF ranging from 1.5 to 3.6 dB. The LNA core dissipates 17 mW from 2.4 V supply, and the chip size occupies 1.1 � 0.9 mm 2 including all pads. The simulated and measured results show good agreement from 8 to 12 GHz.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…In the 2010s, MOSFET scaling reached 5 nm from 32 nm [30] and many studies [161–200, 201–250, 251–300, 301–361] were carried out by focussing on improving the mentioned topologies and techniques which were presented in the 2000s for wideband LNA. As examples, we can refer to ‘the noise/distortion cancelation topologies’ [164, 167, 173, 181, 189, 192, 194, 195, 201, …”

To the best of the author's knowledge, several studies during 1960-2019 were carried out on wideband and ultrawideband LNAs just to render optimum LNAs for SAW-less Radio-Frequency Integrated Circuits (RFICs) but none of these works reviewed and taught the proceedings of these six decades, hence the lack of a comprehensive review is quite noticeable. This article specifically studies the challenges and solutions of designing UWB LNA by reviewing topologies and techniques such as inductive peaking, noise and distortion cancellation, g m -boosting, active inductor and notch filter. Its historical aspect illustrates when the idea of wideband LNA was born and how it changed to ultrawideband LNA, and its tutorial aspect discusses circuits and achievements to present optimum LNAs in Complementary MOS (CMOS), BiCMOS and High-Electron-Mobility Transistor (HEMT) technologies. This work describes the endeavours of engineers in reaching UWB LNA from narrowband LNA during six decades that have great importance as a chapter in understanding this topic because it teaches all topologies, techniques, circuits and related events in a historical narrative for trained readers who are not experts on this topic. | UWB LNA | In the 1960sWhere did the idea of 'transistorised wideband LNA' originate from? It seems that everything goes back to the 1960s when This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…The specifications for LNA in SKA is strict at room temperature and demands best possible response for all the key parameters like noise temperature (NT), gain, bandwidth (BW in GHz), Input and output return losses, linearity, power consumption and chip area. Bhaumik & George (2009) has proposed two figureof-merits which take into account all these factors of MMIC LNA design comprehensively. Higher numerical value of these FOMs signifies better performance.…”

The paper concentrates on summarizing significant worldwide developments in the Low Noise Amplifier domain for the Square Kilometre Array telescope. Several technologies, design topologies and noise measurement techniques of LNAs for SKA have been proposed and analysed since the commencement of the project in 2000. Transistor technologies including GaAs mHEMT, GaAs pHEMT, SiGe HBT, CMOS, InP pHEMT have been extensively studied and characterised at multiple institutes around the world. The proposed site of SKA is either Western Australia or South Africa. Both sites experience a very significant physical temperature variation even over a 24 hour period. Hence temperature dependant studies on the DC, small signal and noise characteristics of different transistors have been carried out. Cryogenic characterisation down to 15K physical temperature of certain types of transistor technologies has also been performed. Both hybrid and MMIC LNAs based on the above technologies have been designed and measured. Depending on the antenna topology and impedance, both single ended and differential LNAs with various input impedances have been explored. Performance of LNA integrated with the antenna has been simulated and the effect of the variation of antenna impedance on the overall performance of the before mentioned components have been studied. Design, development and comprehensive analysis of measured data of both variations of LNA and their pros and cons have been portrayed in this paper. Due to system architecture requirements, differential input-single ended output LNA configuration has been designed and measured. In this paper their advantages, disadvantages and their sources will be identified. Some interesting theories and techniques of differential noise measurements have been proposed during SKA project and will also be explained as part of this paper.
