Detailed modeling of the video signal and optimal readout of charge-coupled devices
(John Wiley & Sons Ltd, 2020-07-07)
This article provides a practical design methodology to calculate an optimal filter for noise reduction in the readout of charge‐coupled devices (CCDs) taking into account the charge transfer and feedthroughs due to ...
Analog pile-up circuit technique using a single capacitor for the readout of Skipper-CCD detectors
(IOP Publishing, 2021-11)
With Skipper-CCD detectors it is possible to take multiple samples of the charge packet collected on each pixel. After averaging the samples, the noise can be extremely reduced allowing the exact counting of electrons per ...
Smart Readout of Nondestructive Image Sensors with Single Photon-Electron Sensitivity
(American Physical Society, 2021-12)
Image sensors with nondestructive charge readout provide single-photon or single-electron sensitivity, but at the cost of long readout times. We present a smart readout technique to allow the use of these sensors in visible ...
Sub-electron readout noise in a Skipper CCD fabricated on high resistivity silicon
(Springer, 2012-05-06)
The readout noise for Charge-Coupled Devices (CCDs) has been the main limitation when using these detectors for measuring small amplitude signals. A scientific CCD fabricated on a high-resistivity silicon substrate utilizing ...
A solution for future single-electron-counting fast-readout Skipper-CCD experiments: high channel density front-end electronics design and noise performance analysis
(SPIE, 2020)
The Skipper-CCDs, a special type of charge-coupled device (CCD) sensor that features sub-electron readout noise levels, was proposed decades ago. However, only in recent years it has been possible to develop large size ...

The J(1)...J(3) is a recent optical method for linear readout of dynamic phase modulation index in homodyne interferometers. In this work, the J(1)... J(3) method is applied to measure voltage in an optical voltage sensor. ...
Achieving sub electron noise in CCD systems by means of digital filtering techniques that lower 1/f pixel correlated noise
(Springer, 2012-07)
Scientific CCDs designed in thick high resistivity silicon (Si) are excellent detectors for astronomy, high energy and nuclear physics, and instrumentation. Many applications can benefit from CCDs ultra low noise readout ...
A multisampling time-domain CMOS imager with synchronous readout circuit
(Springer, 2008-11-01)
A novel multisampling time-domain architecture for CMOS imagers with synchronous readout and wide dynamic range is proposed. The proposed multisampling architecture requires only a single bit per pixel memory instead of 8 ...
