A Survey of Neural Front End Amplifiers and Their Requirements toward Practical Neural Interfaces
Journal of Low Power Electronics and Applications, 2014 When designing an analog front-end for neural interfacing, it is hard to evaluate the interplay of priority features that one must upkeep. Given the competing nature of design requirements for such systems a good understanding of these trade-offs is ...

Low-Noise Programmable Voltage Source [PDF]
Electronics, 2020 This paper presents the design and testing of a low-noise programmable voltage source. Such a piece of instrumentation is often required as part of the measurement setup needed to test electronic devices without introducing noise from the power supply (such as photodetectors, resistors or transistors).

A method for lift coefficient estimation of a pantograph using sparse modelling
Nihon Kikai Gakkai ronbunshu, 2018 It is necessary for pantographs of Japanese high-speed trains to satisfy both low noise characteristics and insensitive lift force characteristics toward the variation in wind direction and in the shape of pantograph head due to wear.

Precise Characterization and Multiobjective Optimization of Low Noise Amplifiers [PDF]
, 2015 Although practically all function blocks of the satellite navigation receivers are realized using the CMOS digital integrated circuits, it is appropriate to create a separate low noise antenna preamplifier based on a low noise pHEMT. Such an RF front end

Low-frequency charge noise in Si/SiGe quantum dots [PDF]
Physical review B, 2019 Electron spins in silicon have long coherence times and are a promising qubit platform. However, electric field noise in semiconductors poses a challenge for most single- and multi-qubit operations in quantum-dot spin qubits.
