The next generation of experiments for light-dark-matter and neutrino searches based on skipper charge-coupled devices (skipper-CCDs) introduces new challenges for the sensor packaging and readout architecture. Scaling the active mass while simultaneously reducing the experimental backgrounds in orders of magnitude requires a novel high-density silicon-based package that must be massively produced...Show More

The Skipper-in-CMOS image sensor integrates the nondestructive readout capability of skipper charge coupled devices (Skipper-CCDs) with the high conversion gain of a pinned photodiode (PPD) in a CMOS imaging process while taking advantage of in-pixel signal processing. This allows both single photon counting as well as high frame rate readout through highly parallel processing. The first results o...Show More

Year: 2022 | Conference Paper |
Charge-Coupled Devices (CCDs) sensors have been at the forefront of high precision and resolution imaging ever since their development. Scientific CCDs and the Skipper-CCD pushed the boundaries for sensing very weak ionizing particles, as they allow to detect without error the charge signal (even a single electron-hole pair) collected on every pixel of the detector. To obtain such precision these ...Show More

The Skipper CCD allows pixel measurements with sub-electron noise levels. The gain of the CCD, that relates the number of electrons to the number of analog to digital units (ADU) is almost linear but with some degree of nonlinearity. This article uses the charge quantization allowed by the Skipper CCD to estimate the gain with different strategies. Linear and quadratic models are analyzed and diff...Show More

2021 Argentine Conference on Electronics (CAE)
Year: 2021 | Conference Paper |
The skipper CCD is a special type of charge coupled device in which the readout noise can be reduced to subelectron levels by averaging independent measurements of the same charge. Thus the charge in the pixels can be determined by counting the exact number of electrons. The total readout time is proportional to the number of measurements of the charge in each pixel. For some applications this tim...Show More
Interleaved Readout of Charge-Coupled Devices (CCDs) for Correlated Noise Reduction
Guillermo Fernandez Moroni;Fernando Chierchie;Leandro Stefanazzi;Eduardo Emilio Paolini;Miguel Sofo Haro;Gustavo Cancelo;Javier Tiffenberg;Juan Estrada
This article proposes a new technique to reduce the readout noise in charge-coupled devices (CCDs). The objective is to minimize the common noise between the channels. This noise is either induced by the readout electronics or by the environment, and it could be present in small (single CCD and a few channels) or large systems (dozens of CCDs and hundreds of channels). By interleaving the video si...Show More
