“…The sensitivity The measurement is done at a temperature of 4.2 K. The Shapiro step is hard to observe in the IV curve, but in the differential resistance, it can be clearly seen to light in a broad range of frequencies has lead to numerous applications. The microwave sensitivity is applied in technologies like multiplexers, cryogenic receivers, delay lines, and antennas [14][15][16], while the infrared sensitivity is used in for space detectors [17]. In the search of potential applications for modern electronics, here we report an observation of giant Shapiro steps in the artificially made superconducting nanostructures with controlled complexity.…”

“…One possible application takes advantage of the SQUID's extreme sensitivity to magnetic flux to create compact, wideband antennas, sensitive to high-frequency magnetic fields, as opposed to electric fields [68][69][70][71]. Other possible applications include low noise amplifiers for rf sensing and qubit readout [63,72,73] and highly sensitive magnetometers and filters [74][75][76].…”

Funding for Open Access provided by the UMD Libraries Open Access Publishing Fund.We have prepared meta-atoms based on radio-frequency superconducting quantum-interference devices (rf SQUIDs) and examined their tunability with dc magnetic field, rf current, and temperature. rf SQUIDs are superconducting split-ring resonators in which the usual capacitance is supplemented with a Josephson junction, which introduces strong nonlinearity in the rf properties. We find excellent agreement between the data and a model that regards the Josephson junction as the resistively and capacitively shunted junction. A magnetic field tunability of 80 THz=G at 12 GHz is observed, a total tunability of 56% is achieved, and a unique electromagnetically induced transparency feature at intermediate excitation powers is demonstrated for the first time. An rf SQUID metamaterial is shown to have qualitatively the same behavior as a single rf SQUID with regard to dc flux and temperature tuning.This work is supported by the NSF-GOALI Program through Grant No. ECCS-1158644 and the Center for Nanophysics and Advanced Materials (CNAM).

“…The 1990s can be named 'CMOS & BiCMOS Decade', though the wide range of RF designs were rendered at that time [32][33][34][35][36][37][38][39][40][41][42][43][44]. The significance of the CMOS [41] and the BiCMOS [35,38] was due to the capability of MOS in scaling (getting smaller in size during the next decades) [30], its characteristics as a voltage-controlled device [45], and also the properties of BJT such as high voltage-gain, high frequency-range, and its ability to compete with other technologies in results [41].…”

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.
