IEEE Journal of the Electron Devices Society, 2016 A new method for characterizing deep sub-electron read noise image sensors is reported. This method, based on the photon-counting histogram, can provide easy, independent and simultaneous measurements of the quanta exposure, conversion gain, and read ...

A Low-Noise and High-Integration Readout IC with Pixel-Level Single-Ended CDS for Short-Wave Infrared Focal Plane Arrays [PDF]
SensorsImproving sensitivity in short-wave infrared (SWIR) detection is crucial for low-signal applications, such as astronomy and hyperspectral imaging, which demand readout integrated circuits (ROICs) with minimal noise and high density. However, conventional

Analog Read Noise and Quantizer Threshold Estimation From Quanta Image Sensor Bit Density
IEEE Journal of the Electron Devices Society, 2022 Estimation of the analog read noise level and quantizer threshold level to within a few hundredths of an electron can be obtained by measuring the output bit density, D, of a single-bit quanta image sensor (1bQIS) as a function of quanta exposure, H ...

Noise reduction by upstream open reading frames
Nature Plants, 2022 AbstractGene expression is prone to burst production, making it a highly noisy process that requires additional controls. Upstream open reading frames (uORFs) are widely present in the 5′ leader sequences of 30–50% of eukaryotic messenger RNAs1–3. The translation of uORFs can repress the translation efficiency of the downstream main coding sequences ...

Sensory white noise improves reading skills and memory recall in children with reading disability [PDF]
Brain and Behavior, 2021 Abstract Background Reading disability (RD) is characterized by slow and inaccurate word reading development, commonly reflecting underlying phonological problems. We have previously shown that exposure to white noise acutely improves cognitive performance in children with ADHD.

Visual noise disrupts conceptual integration in reading [PDF]
Psychonomic Bulletin & Review, 2010 The Effortfulness Hypothesis suggests that sensory impairment (either simulated or age-related) may decrease capacity for semantic integration in language comprehension. We directly tested this hypothesis by measuring resource allocation to different levels of processing during reading (i.e., word vs. semantic analysis).

Subelectron read noise at MHz pixel rates [PDF]
SPIE Proceedings, 2001 A radically new CCD development by Marconi Applied Technologies has enabled substantial internal gain within the CCD before the signal reaches the output amplifier. With reasonably high gain, sub-electron readout noise levels are achieved even at MHz pixel rates.

A 45 nm Stacked CMOS Image Sensor Process Technology for Submicron Pixel
Sensors, 2017 A submicron pixel’s light and dark performance were studied by experiment and simulation. An advanced node technology incorporated with a stacked CMOS image sensor (CIS) is promising in that it may enhance performance. In this work, we demonstrated a low
