In this paper, an ultra-wideband (UWB) common gate low-noise amplifier (LNA) with gm-boosted and noise-cancelling techniques is presented. In this scheme we utilize gm-boosted stage for cancelling the noise of matching device. The bandwidth extension and flat gain are achieved by using of series and shunt peaking techniques. Simulated in .13 um Cmos technology, the proposed LNA achieved 2.38-3....

Design of Global Positioning System (GPS) receiver with a low noise amplifier (LNA) in the front end remains a major design requirement for the success of modern day navigation and communication system. Any LNA is expected to meet the requirements like its ability to add the least amount of noise while providing sufficient gain, perfect input and output matching, and high linearity. However, mo...

'Locked nucleic acids' (LNAs) are known to introduce enhanced bio- and thermostability into natural nucleic acids rendering them powerful tools for diagnostic and therapeutic applications. We present the 1.9 Å X-ray structure of an 'all LNA' duplex containing exclusively modified β-D-2'-O-4'C-methylene ribofuranose nucleotides. The helix illustrates a new type of nucleic acid geometry that cont...

This paper presents linearity enhancement technique for GHzband low noise amplifier (LNA). To verify this technique, we designed LNA using 0.18-μm BiCMOS process. Linearity is very important parameter for LNA. The MOS-BJT derivative superposition (MBDS) technique is exploited by a parallel LC tank in the emitter of bipolar transistor to reduce the secondorder non-linear coefficient (gm2) relate...

Latent nuclear antigen (LNA) is implicated in Kaposi's sarcoma-associated herpesvirus (KSHV) episome persistence. LNA colocalizes with KSHV episomes on chromosomes in metaphase, and it maintains the stability and replication of KSHV terminal repeat-containing plasmids. In this study, we examined the function of LNA in episome persistence in the context of full-length KSHV genome by mutagenesis ...
