A low noise cascode amplifier

open access: yesJournal of Research of the National Bureau of Standards, 1987
We describe the design, schematics, and performance of a very low noise FET cascode input amplifier. This amplifier has noise performance of less than [Formula: see text] and 0.25 [Formula: see text] over the 500 Hz to 50 kHz frequency range. The amplifier is presently being used in conjunction with a Penning ion trap but is applicable to a wide ...

Weak Capacitance Detection Circuit of Micro-Hemispherical Gyroscope Based on Common-Mode Feedback Fusion Modulation and Demodulation

open access: yesMicromachines, 2023
As an effective capacitance signal produced by a micro-hemisphere gyro is usually below the pF level, and the capacitance reading process is susceptible to parasitic capacitance and environmental noise, it is highly difficult to acquire an effective ...

Biosignal Amplifiers Based on Low‐Noise Organic Transistors with Printed Electrodes

open access: yesAdvanced Electronic Materials, 2023
The monitoring of microvolt‐level biosignals such as electroencephalograms requires the application of low‐noise signal amplifier circuits, which, for single‐use cases, must be fabricated for disposability using low‐cost manufacturing techniques.

Low rank prior in single patches for non-pointwise impulse noise removal [PDF]

open access: yes, 2015
This paper introduces a low rank prior in small oriented noise-free image patches: Considering an oriented patch as a matrix, a low-rank matrix approximation is enough to preserve the texture details in the optimally oriented patch.

The masking-level difference in low-noise noise.

open access: yesThe Journal of the Acoustical Society of America, 1996
The masking-level difference for a 500-Hz pure tone signal was examined for an interaurally in-phase noise having different degrees of power fluctuations. MLDs were reliably smaller in noise having relatively low power fluctuations. This effect was due to the following trends in the threshold data. (1) For all subjects, the So threshold improved as the
