| The tuned amplifier using a parallel LC network provides selective amplification and lower power consumption. | |
109 Citations | This technique has the potential for extremely-high-speed operation and allows continuous tuning of both input and output wavelengths over the amplifier gain bandwidth. |
| Wheeler's double-tuned impedance-matching relationship is the best overall measure of the achievable fractional bandwidth for an antenna. | |
| By varying the biasing voltage of the non-Foster circuit, the impedance can be tuned from 250 to 420 jΩ, while maintaining low dispersion over the same bandwidth. | |
02 Apr 2015 | In this work we have demonstrated a novel technique to achieve high bandwidth in differential amplifier. |
| A bandwidth of 50 GHz is the highest bandwidth ever reported for a broad-band differential amplifier in any technology. | |
| The experiments further show that this bandwidth can be tuned to a larger value at the expense of a lower enhancement factor and this by changing one of the bias voltages. | |
| We present an impedance engineered Josephson parametric amplifier capable of providing bandwidth beyond the traditional gain-bandwidth product. | |
96 Citations | The antenna bandwidth can be flexibly tuned from 2.2% to 21.3%, and simultaneously good filtering performance is kept during the tuning of different states. |
| The proposed amplifier achieves at least two times improvement in bandwidth-to-power and slew-rate-to-power efficiencies than all other reported multistage amplifiers using different compensation topologies. | |
26 Citations | The results show that for all resonant circuit geometries (series, parallel, series-parallel), overcoupling of the line to the tuned circuit is key to obtaining a large tuning bandwidth. |
316 Citations | With proper output filtering, the amplifier can be operated over nearly an octave bandwidth with less than a 5 percent reduction in efficiency. |
| Also, we show that this extremely broad bandwidth can be tuned to higher or lower central wavelengths by changing either the pump frequency or the crystal temperature. | |
01 Oct 2003 43 Citations | This amplifier achieves 13 dB gain and more than 80 GHz bandwidth, which is the highest bandwidth reported so far for Si-based amplifiers. |
| The letter proposes that the technique of reactance compensation, previously applied successfully to improve the bandwidth of parametric amplifiers, can be applied to varactor-tuned oscillators, such as Gunn oscillators, with significant improvement in the electronic-tuning range. | |
| To the authors' knowledge, this is the highest proven bandwidth of a broadband amplifier in TS technology. | |
37 Citations | The new circuit possesses the gain accuracy and bandwidth of the current feedback amplifier but realizes significant improvement in bandwidth accuracy and bandwidth gain-independence. |
| Nevertheless, the authors also propose an alternative based on multi-tuned EBGs, in order to obtain a comparable fractional bandwidth. | |
| The performance of this electronically tuned filter is promising in terms of continuous center-frequency and bandwidth tunings. |
