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

The masking-level difference in low-noise noise.
The 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

Noise-optimized ultrastable low-noise current amplifier [PDF]
Review of Scientific Instruments, 2019 We have developed a noise-optimized ultrastable low-noise current amplifier (ULCA) aimed at reducing the uncertainty at low currents. It involves a thin-film resistor network with 6.75 GΩ at the high-ohmic path which reduces the noise level to 1.6 fA/Hz. Noise investigations as well as short-term and long-term stability studies were carried out.

Low-discrepancy blue noise sampling [PDF]
ACM Transactions on Graphics, 2016 We present a novel technique that produces two-dimensional low-discrepancy (LD) blue noise point sets for sampling. Using one-dimensional binary van der Corput sequences, we construct two-dimensional LD point sets, and rearrange them to match a target spectral profile while preserving their low discrepancy.
