On the possibility of breaking the heterodyne detection quantum noise limit with cross-correlation
(Institute of Electrical and Electronics Engineers Inc., 2018)
The cross-correlation sensitivity of two identical balanced photodiode heterodyne receivers
is characterized. Both the balanced photodiodes receive the same weak signal split up equally, a situation
equivalent to an ...
Low-Frequency noise investigation of AlGaN/GaN high-electron-mobility transistors
(2021-09-01)
In this paper, the noise Power Spectral Density (PSD) of AlGaN/GaN High-Electron-Mobility Transistors (HEMTs) has been experimentally investigated in linear operation (VD = 50 mV) for different channel lengths (L) and ...
Plug-and-play transceiver with high gain and ultra low noise figure for IEEE 802.15.4 application
(2019-06)
This paper shows the design and performance simulation of a 2.4 GHz plug-
and-play transceiver based on a high speed switch for IEEE 802.15.4 applications. The
electrical design was optimized taking into account the ...
Analog Figures of Merit of Vertically Stacked Silicon Nanosheets nMOSFETs With Two Different Metal Gates for the Sub-7 nm Technology Node Operating at High Temperatures
(Ieee-inst Electrical Electronics Engineers Inc, 2021-07-01)
The analysis of vertically stacked nanosheet (NS) n-type transistors with two different metal gate-stacks (with a total thickness of 7.5 and 4.7 nm) is presented in this work from room temperature to 200 degrees C. The ...
Avaliação do ruído e temperatura na aplicação de concreto betuminoso usinado quente: CBUQ
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2014-04-15)
With this research we sought to assess the working conditions under which employees paving exclusively evaluating the enforcement team of asphalt concrete hot machined, are set forth with respect to noise and temperature. ...

Model for electron spin resonance in STM noise
(American Physical Society, 2014-02)
We propose a model to account for the observed ESR-like signal at the Larmor frequency in the current noise scanning tunnel microscope (STM) experiments identifying spin centers on various substrates. The theoretical ...
Efectos de controlabilidad y magnitud de ruido en comportamiento de evitación, cortisol salival y temperatura
(Conductual, Revista Internacional de Interconductismo y Análisis de Conducta, 2014)
