“…Several LNAs with hybrid methods for noise reduction have been proposed [21][22][23][24]. Various LNAs with FFNC have integrated cascode amplifiers [21], parallel structures with push-pull stages [22], or dual-RLC-branch input matching networks [23] to improve noise performance. Cross-coupled LNAs have employed shuntshunt transformer dual feedback [24].…”

An ultra‐wideband (UWB) low‐noise amplifier (LNA) implemented using 180 nm complementary metal–oxide–semiconductor technology is presented for wireless personal area network (WPAN) and wireless body area network (WBAN). Increasing the resistance of the substrate resistor RB reduces the noise factor. When additional substrate resistors and a composite feedback topology are employed, the proposed LNA can achieve both a 1.4 dB reduction of the noise figure (NF) and a 4 dB enhancement in power gain (PG). Over the operating frequency range from 3.1 to 4.8 GHz, the LNA achieves a maximum PG of 14.5 dB, a minimum NF of 1.5 dB, and an input return loss of <10 dB. The measured current consumption is 3 mA with a 1.5 V supply voltage. The active chip area is 0.008 mm2. The proposed 3.1–4.8 GHz LNA has a superior NF, smaller active area, and the lowest dc power consumption compared with devices reported in the literature.

This Letter presents the design and analysis of a tunable low noise amplifier (LNA) capable of achieving single band, dual band and wideband operations. The circuit features a modified tunable open stub matching to achieve a reconfigurable multiband response. The LNA adopts a varactor diode in the input matching stage to achieve reconfigurable modes. Two bias conditions for the varactor diode are analysed. The forward bias condition yields a wideband mode (1.6 to 2.5 GHz) and zero bias results in a concurrent dual band mode (0.9 and 1.7-2.5 GHz). In reverse bias condition, the bias voltage of varactor diode (V d−rb) can be tuned to achieve one single band mode (1 GHz), and a tunable concurrent dual band mode, where the first band is fixed at 1 GHz and the second band is continuously tunable from 1.7 to 2.5 GHz. The LNA is fabricated in microwave integrated circuit process on an FR-4 board. The measured power gain is 7-15 dB and noise figure is 1.2-2.2 dB across all bands. The measured 1 dB compression (P 1 dB) is −4, −3 and −6 dBm at 0.9, 1 and 2.4 GHz, respectively.

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.
