This paper describes a 1.9 GHz, 25 mW , 0.25 μm CMOS Low Noise Amplifier (LNA), intended for use in a DECT (Digital Enhanced Cordless Communications) Receiver. The LNA has been simulated with Cadence Spectre and the results show that it provides a gain of more than 15 dB, for a noise figure of 2dB, and an input referred IP3 of −5dBm. We present the LNA architecture and the circuit analysis alon...

A VHF (30MHz-300MHz) band digitally programmable low noise amplifier (LNA) has been implemented with a 0.25um standard CMOS process for VHF CMMB mobile TV tuners. Utilizing a T-match input network, input matching of more than a decade bandwidth is achieved across all gain settings. Adopting the multiple gated technique, gain flatness enhancement and capacitor reuse etc., the proposed LNA demons...

This paper reports an area-efficient LNA design using an active inductor which can be realised in various UHF band receivers. The overall low noise performance of LNA is achieved by cancelling the inductor noise through additional feed forward path. This circuit is implemented using 0.18μm CMOS technology with cadence environment and its operating range is 0.4 to 1GHz. Design is simulated in vi...

Depending on whether frequency domain duplexing or time domain duplexing (TDD) is used, one antenna can be shared by both transmitter and receiver via a frequencyselective diplexer or an RF switch. Additionally, a band-pass filter may be inserted before the LNA to prevent blocking or desensitization by a strong out-of-band interferer. However, both the duplexer and the filter have losses. As th...

MOTIVATION Network alignment (NA) aims to find regions of similarities between species' molecular networks. There exist two NA categories: local (LNA) and global (GNA). LNA finds small highly conserved network regions and produces a many-to-many node mapping. GNA finds large conserved regions and produces a one-to-one node mapping. Given the different outputs of LNA and GNA, when a new NA metho...

On a low-Na(+) diet (LNa(+)), urinary Na(+) loss is prevented by aldosterone-induced Na(+) reabsorption through epithelial Na(+) channels (ENaC) in the connecting tubules (CNT) and cortical collecting ducts (CCD). However, the mechanism whereby K(+) loss is minimized and Na(+) reabsorption is maximized in the face of a reduced lumen-to-bath Na(+) gradient is not fully understood. The large-cond...

A cascode LNA was optimized for a GPS receiver radio frequency front end using a 0.18 μm CMOS technology. By careful choice of device geometry, gate and source degeneration inductors, a fully integrated LNA can be optimized to have a low noise figure, a high voltage gain and a wide dynamic range. The optimized LNA has a 1.512 dB noise figure, a –42.05 dB S11, a 20.04 dB voltage gain a –19.82 dB...

Thymin-1-yl-acetic acid and adenin-9-yl-acetic acid have been coupled to the N2'-atom of a 2'-amino-LNA thymine nucleoside, and these "double-headed" LNA monomers have been incorporated into oligodeoxyribonucleotides via their corresponding phosphoramidite derivatives. Oligonucleotides containing these modified nucleotides show in most cases increased thermal stability when forming duplexes wit...

The performance of radio-frequency integrated circuit (RFIC) blocks such as low noise amplifiers (LNA) or mixers is enhanced by achieving a simultaneous noise and power match at the input. This paper presents a design strategy for achieving this match for circuits built from bipolar transistors with inductive degeneration. The strategy is applied to the design of a 17.35 GHz LNA and a 17.35 GHz...

Low Noise Amplifier, CMOS, Noise Canceling, Technique. This paper presents a 0.8V, 3.6GHz narrow band CMOS low noise amplifier (LNA). A current-reused technique is employed to increase the gain of LNA. Also, in order to achieve low noise figure, a noise canceling technique is used in the output stage. The high gain LNA was designed and simulated in 0.13 μm CMOS process. A gain of 27 dB at 3.6GH...
