Space optical instruments optimisation thanks to CMOS image sensor technology [PDF]

open access: yes, 2005
Today, both CCD and CMOS sensors can be envisaged for nearly all visible sensors and instruments designed for space needs. Indeed, detectors built with both technologies allow excellent electro-optics performances to be reached, the selection of the most

Asymmetric Contact Engineering for Bottleneck‐Free Transport in 2D MoS2 Field‐Effect Transistor

open access: yesAdvanced Functional Materials, EarlyView.
Performance of 2D semiconductor transistors is limited by carrier transport bottlenecks arising from specific device geometries. By identifying this structural limitation, a bottleneck‐free asymmetric transistor architecture (BATA) is introduced to improve carrier transport.

The Design of a Single-Bit CMOS Image Sensor for Iris Recognition Applications

open access: yesSensors, 2018
This paper presents a single-bit CMOS image sensor (CIS) that uses a data processing technique with an edge detection block for simple iris segmentation. In order to recognize the iris image, the image sensor conventionally captures high-resolution image

Conductance‐Dependent Photoresponse in a Dynamic SrTiO3 Memristor for Biorealistic Computing

open access: yesAdvanced Functional Materials, EarlyView.
A nanoscale SrTiO3 memristor is shown to exhibit dynamic synaptic behavior through the interaction of local electrical and global optical signals. Its photoresponse depends quantitatively on the conductance state, which evolves and decays over tunable timescales, enabling ultralow‐power, biorealistic learning mechanisms for advanced in‐memory and ...

Characterization of Quanta Image Sensor Pump-Gate Jots With Deep Sub-Electron Read Noise

open access: yesIEEE Journal of the Electron Devices Society, 2015
Characterization of quanta image sensor pixels with deep sub-electron read noise is reported. Pixels with conversion gain of $423\mu \text{V}$ /e- and read noise as low as 0.22e- r.m.s. were measured.

RTS noise impact in CMOS image sensors readout circuit [PDF]

open access: yes, 2010
CMOS image sensors are nowadays widely used in imaging applications even for high end applications. This is really possible thanks to a reduction of noise obtained, among others, by Correlated Double Sampling (CDS) readout.
