Matched wideband low-noise amplifiers for radio astronomy [PDF]

open access: yes, 2009
Two packaged low noise amplifiers for the 0.3–4 GHz frequency range are described. The amplifiers can be operated at temperatures of 300–4 K and achieve noise temperatures in the 5 K range (

Programmable Gain Amplifiers with DC Suppression and Low Output Offset for Bioelectric Sensors

open access: yesSensors, 2013
DC-offset and DC-suppression are key parameters in bioelectric amplifiers. However, specific DC analyses are not often explained. Several factors influence the DC-budget: the programmable gain, the programmable cut-off frequencies for high pass filtering

On Oblivious Amplification of Coin-Tossing Protocols [PDF]

open access: yes, 2019
We consider the problem of amplifying two-party coin-tossing protocols: given a protocol where it is possible to bias the common output by at most ?, we aim to obtain a new protocol where the output can be biased by at most ?* < ?.

Spatial power combiner using a planar active transmitarray of stacked patches

open access: yesJournal of Telecommunications and Information Technology, 2005
An X-band spatial power combiner, which uses a planar transmitarray (TXA) of orthogonally polarized stacked microstrip patches integrated with input and output ports of transistor amplifiers is described.

The Use of Cryogenic HEMT Amplifiers in Wide Band Radiometers [PDF]

open access: yes, 2000
Advances in device fabrication, modelling and design techniques have made wide band, low noise cryogenic amplifiers available at frequencies up to 106 GHz. Microwave radiometry applications as used in radio astronomy capitalize on the low noise and large

A Survey of Low Voltage and Low Power Amplifier Topologies

open access: yesJournal of Low Power Electronics and Applications, 2018
Reducing voltage supply is one of the most effective way to reduce the power consumption, but, on the other hand it is a challenging choice for the analog designers.

The cochlear amplifier [PDF]

open access: yesCurrent Biology, 2004
What is it? It's the ear's built-in hearing aid. If your cochlea, the organ of hearing, did not amplify sounds the mechanical vibrations would be about hundred times too small to activate the sensory hair cells. The cochlear amplifier describes the collection of processes that increase sound vibrations in the inner ear.Why should we be interested in ...

Am I Way Wrong on this One? On the Multiple Semantic Sources and Paths of Development of the Amplifier Way in American English

open access: yesLexis: Journal in English Lexicology, 2020
This article explores the diachronic semantic development of the intensifier way in American English. It has been claimed in the literature that the intensifying function of way derives from the use of spatial adverbial (a)way, but I propose that this ...

Insulting Rhetorical Questions – Mitigators or Amplifiers?

open access: yesRespectus Philologicus, 2022
The paper examines whether rhetorical questions (RQs) with insulting content or implications soften or intensify the insulting content that they express, as compared to corresponding direct statements with similar insulting content.

A correlation noise spectrometer for flicker noise measurement in graphene samples [PDF]

open access: yes, 2019
We present a high-resolution digital correlation spectrum analyzer for the measurement of low frequency resistance fluctuations in graphene samples. The system exploits the cross-correlation method to reject the amplifiers' noise.
