This work presents a 2.4 GHz low noise amplifier (LNA) for wireless sensor network in CMOS 0.13-μm Silterra process. The forward body bias technique with cascode configuration has been adopted in order to implement a suitable LNA for low power consumption target. The supply voltage was varied from 0.4 V to 0.6 V as to optimize the tradeoffs for LNA performances. The simulation results show that...

A broadband input matching technique for low noise amplifiers (LNAs) is presented which exploits an active feedback network to achieve better noise performance. The presented matching scheme is compared to the common-gate and conventional noise canceling structures. The noise performance of the presented technique is similar to that of the conventional noise canceling technique with much less p...

Therapeutic application of the recently discovered small interfering RNA (siRNA) gene silencing phenomenon will be dependent on improvements in molecule bio-stability, specificity and delivery. To address these issues, we have systematically modified siRNA with the synthetic RNA-like high affinity nucleotide analogue, Locked Nucleic Acid (LNA). Here, we show that incorporation of LNA substantia...

144606-7171-IJET-IJENS © December 2014 IJENS I J E N S Abstract— This paper shows the design of a broadband low noise amplifier (LNA) for ultra-wideband (UWB) applications. The proposed LNA uses cascode configuration technique followed by an inductive inter-stage network to realize the flat gain throughout the UWB band. The inductive inter-stage network is cascaded to a common source amplifier ...

In this work, design and simulation results of two RF front-ends to be used in direct conversion receiver are presented. The first one uses dual CS differential LNA with folded mixer. The second one uses single-ended LNA with double balanced mixer. Single-ended and fully differential LNA’s provide gains of 16.3 dB and 28.75 dB at 2.4GHz, respectively. Noise Figure of these two LNA’s are 3.34 dB...

The design issues in designing low noise amplifier (LNA) for Software-Defined-Radio (SDR) are reviewed. An inductor-less wideband low noise amplifier aiming at low frequency band (0.2-2 GHz) for Software-DefinedRadio is presented. Shunt-shunt LNA with active feedback is used as the first stage which is carefully optimized for low noise and wide band applications. A digitally controlled second s...

In this paper, a CMOS low-noise amplifier (LNA) with a new input matching topology has been proposed, analyzed and measured. The input matching network is designed through the technique of capacitive feedback matching network. The proposed LNA which is implemented in a 0:18-mm1P6M CMOS technology is operated at the frequency of 12.8GHz. It has a gain S21 of 13.2 dB, a noise figure (NF) of 4.57 ...

A gain boosting method without noise-figure degradation by optimizing interstage matching in a cascode low-noise amplifier (LNA) with emitter-degeneration inductor is demonstrated at 5.2 GHz using 2m GaInP/GaAs HBT technology. A low-pass LC matching network is inserted in the interstage of a conventional cascode LNA with emitter-degeneration-inductor to enhance the gain with the same current co...

We quantified incorporation rates of plasmaderived a-linolenic acid (a-LNA, 18:3n-3) into “stable” liver lipids and the conversion rate of a-LNA to docosahexaenoic acid (DHA, 22:6n-3) in male rats fed, after weaning, an n-3 PUFA-adequate diet (4.6% a-LNA, no DHA) or an n-3 PUFAdeficient diet (0.2% a-LNA, no DHA) for 15 weeks. Unanesthetized rats were infused intravenously with [1-C]a-LNA, and a...

The increasing worldwide aquaculture output and concomitant decrease in the stocks of feedgrade fish used for fish oil production has made fish oil replacement in feeds a priority for the aquaculture industry. The regulation of fatty acid metabolism in fish is important in order to determine strategies for the best use of plant oils in diets for commercially important cultured fish species. We ...
