A highly linear, low voltage, low power, low noise amplifier (LNA) using a novel nonlinearity cancellation technique is presented in this paper. Parallel Inductor (PI) matching is used to increase LNA gain by 3 dB at the desired frequency. The linear LNA was designed and simulated in a TSMC 0.18μm CMOS process at 5GHz frequency. By employing the proposed technique, the IIP3 is improved by 12 dB...

Locked Nucleic Acid (LNA) is a unique nucleic-acid modification possessing very high binding affinity and excellent specificity toward complementary RNA or DNA oligonucleotides. The remarkable properties exhibited by LNA oligonucleotides have been employed in different nucleic acid-based therapeutic strategies both in vitro and in vivo. Herein, we highlight the applications of LNA nucleotides f...

Direct sequencing remains the most widely used method for the detection of epidermal growth factor receptor (EGFR) mutations in lung cancer; however, its relatively low sensitivity limits its clinical use. The objective of this study was to investigate the sensitivity of detecting an epidermal growth factor receptor (EGFR) mutation from peptide nucleic acid-locked nucleic acid polymerase chain ...

This paper describes a high-gain CMOS low-noise amplifier (LNA) for 2.4/5.2-GHz WLAN applications. The cascode LNA uses an inductor at the common-gate transistor to increase its transconductance equivalently, and therefore it enhances the gain effectively with no additional power consumption. The LNA is matched concurrently at the two frequency bands, and the input/output matching networks are ...

A novel 2',4'-BNA/LNA analog bridged by guanidine, termed as guanidine bridged nucleic acid (GuNA), was synthesized and incorporated into oligonucleotides. Thermal stabilities and nuclease resistance of GuNA-modified oligonucleotides were investigated and compared with those of 2',4'-BNA/LNA and natural DNA oligonucleotides. GuNA exhibited interestingly high binding affinity towards complementa...

The Low Noise Amplifier (LNA) is very much important in achieving good reception sensitivity in the wideband transceiver of Ultra Wide Band (UWB) architecture. In this paper, the LNA is designed for Multi Band-Orthogonal Frequency Division Multiplexing (MB-OFDM) receiver, which is used to transmit the information on 14 different sub bands of UWB with minimum of 528 MHz frequency in each band. T...

Due to an increasing demand for simultaneous global roaming and all-in-one wireless phones, the interest in the development of the multi-standard transceivers has been increased. In the receiver front end, the performance of Low Noise Amplifier (LNA) decides overall receiver sensitivity and hence its design plays a crucial role. In this paper, an active inductor based tunable two-stage LNA empl...

Synthesis of chimeric 9-mer oligonucleotides containing methylphosphonate-linkages and locked nucleic acid (LNA) monomers, their binding affinity towards complementary DNA and RNA, and their 3'-exonucleolytic stability are described. The obtained methylphosphonate-DNA/LNA chimeric oligonucleotides display similarly high RNA affinity and RNA selectivity as a corresponding 9-mer DNA/LNA chimeric ...

Locked Nucleic Acid (LNA) is a nucleic acid analogue with unprecedented binding affinity and excellent specificity toward complementary RNA and DNA oligonucleotides. The remarkable properties of LNA have led to applications within various gene silencing strategies both in vitro and in vivo. In the present review, we highlight the uses of LNA for regulation of gene expression with emphasis on RN...
