This paper presents a 23–32 GHz wideband BiCMOS low-noise amplifier (LNA). The LNA utilizes coupled-resonators to provide a wideband load. To our knowledge, the proposed LNA achieves the widest bandwidth with minimum power consumption using 0.18 m BiCMOS technology in K-band. Analytical expressions for the wideband input matching, gain, noise figure and linearity are presented. The LNA is imple...

This paper presents a multi-band low-noise amplifier (LNA) in the 45-nm CMOS silicon-on-insulator (SOI) process. The LNA consists of three stages, with differential cascode as core structure. first stage is mainly responsible for input matching to ensure favourable noise characteristics and bandwidth, while subsequent stages increase gain. Moreover, utilizes baluns input/output interstage imped...
Rates of conversion of alpha-linolenic acid (alpha-LNA, 18:3n-3) to docosahexaenoic acid (DHA, 22:6n-3) by the mammalian brain and the brain's ability to upregulate these rates during dietary deprivation of n-3 polyunsaturated fatty acids (PUFAs) are unknown. To answer these questions, we measured conversion coefficients and rates in post-weaning rats fed an n-3 PUFA deficient (0.2% alpha-LNA o...
High affinity antisense oligonucleotides (ASOs) containing bicylic modifications (BNA) such as locked nucleic acid (LNA) designed to induce target RNA cleavage have been shown to have enhanced potency along with a higher propensity to cause hepatotoxicity. In order to understand the mechanism of this hepatotoxicity, transcriptional profiles were collected from the livers of mice treated with a ...
The effect of locked nucleic acid (LNA) modification position upon representative DNA polymerase and exonuclease activities has been examined for potential use in primer extension genotyping applications. For the 3'-->5' exonuclease activities of four proofreading DNA polymerases (Vent, Pfu, Klenow fragment and T7 DNA polymerase) as well as exonuclease III, an LNA at the terminal (L-1) position...
BACKGROUND Modified nucleotides are increasingly being utilized in the de novo selection of aptamers for enhancing their drug-like character and abolishing the need for time consuming trial-and-error based post-selection modifications. Locked nucleic acid (LNA) is one of the most prominent and successful nucleic acid analogues because of its remarkable properties, and widely explored as buildin...
Narrow band Low Noise Amplifiers (LNA) use inductors for band selection and input matching to reduce power consumption and reduce thermal noise generation. The LNA amplifies all signals within its fixed band, including blocking signals. This requires a larger dynamic range from the rest of the front end (mixers and analog to digital converters (ADC)). This paper presents a solid state active in...
Effects of four levels of dietary linoleic acid (LA), an n-6 fatty acid, and four levels of alpha-linolenic acid (LNA), an n-3 fatty acid, and their interactions on immune responses in growing layer hens were studied. Immune responses were induced by injection with keyhole limpet hemocyanin (KLH) or Mycobacterium butyricum particles at 35 d of age. Antibody (Ab) responses were measured until 21...
EGSs (external guide sequences) are short antisense oligoribonucleotides that elicit RNase P-mediated cleavage of a target mRNA, which results in inhibition of gene expression. EGS technology is used to inhibit expression of a wide variety of genes, a strategy that may lead to development of novel treatments of numerous diseases, including multidrug-resistant bacterial and viral infections.
