2020 IEEE 2nd International Conference on Artificial Intelligence in Engineering and Technology (IICAIET), 2020
Radio frequency identification (RFID) technology is currently reader protocol specific. For a common RFID standard to be used as the internet of things (IoT) devices, the reader should either be general or be avoided to facilitate tag communication with a common protocol.

2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007
A monolithic low-noise-amplifier operating in the 60 GHz band is presented. The circuit has been designed utilizing an advanced 0.25 mum SiGe BiCMOS technology, featuring npn transistors with fT and fmax ap 200 GHz. A two stage cascode architecture has been chosen for the implementation.

LNA noise parameter measurement
2015 European Conference on Circuit Theory and Design (ECCTD), 2015Joint measurement of stochastic parameters of a low noise amplifier (LNA), based on output power measurement for input termination impedances is considered. As an advantage of this method the noise parameters can be determined in a quick way for narrow and broad band applications without special equipment.

A comparative study of CMOS LNAs
2007 18th European Conference on Circuit Theory and Design, 2007Three CMOS RF low noise amplifier circuits have been designed and simulated. These LNAs are intended for use in 402-405 MHz medical implant communication service transceivers. The inductively degenerated common source LNA (CS-LNA) topology is currently popular because it achieves high gain, low noise figure, and high linearity.

On the Output Impedance of Integrated LNAs
2019 IEEE International Symposium on Circuits and Systems (ISCAS), 2019We show that the output impedance of an integrated LNA need not to be matched to 50 Ω for measurement purposes. The result is true for LNAs, both stand-alone or otherwise, that are designed to drive voltage-input or current-input mixers. We show that 50 Ω output impedance matching is detrimental to the performance of the LNA.

Nucleosides and Nucleotides, 1999
Abstract LNA (Locked Nucleic Acid) forms duplexes with complementary DNA, RNA or LNA with unprecedented thermal affinities. CD spectra show that duplexes involving fully modified LNA (especially LNA:RNA) structurally resemble an A-form RNA:RNA duplex. NMR examination of an LNA:DNA duplex confirm the 3′-endo conformation of an LNA monomer.

Synthesis and Hybridization Studies of 2‘-Amino-α-L-LNA and Tetracyclic “Locked LNA”
The Journal of Organic Chemistry, 2006A convergent route to a new class of locked nucleic acids, i.e., 2'-amino-alpha-L-LNA, has been developed. The optimized synthetic route to the corresponding phosphoramidite building block of thymine proceeds in 4% overall yield over 15 steps from the starting diol.
