DECAL: A Reconfigurable Monolithic Active Pixel Sensor for use in Calorimetry and Tracking
Proceedings of Topical Workshop on Electronics for Particle Physics — PoS(TWEPP2019), 2020 In this paper we describe the DECAL Monolithic Active Pixel Sensor (MAPS) for digital electromagnetic calorimetry. The sensor consists of a matrix of 64x64 55um pixels, and provides a readout at 40MHz of the number of particles which have struck the ...

DEPFET Active Pixel Sensors [PDF]
Proceedings of The 16th International Workshop on Vertex detectors — PoS(Vertex 2007), 2008 DEPFET pixels offer a unique possibility for a high resolution pixel vertex detector at a future linear collider (ILC) experiment. The key idea of DEPFET sensors is the integration of amplifying transistors into a fully depleted bulk. The excellent noise performance obtained through the low input capacitance in combination with the full signal from the

Performance of active edge pixel sensors [PDF]
Journal of Instrumentation, 2017 To cope with the High Luminosity LHC harsh conditions, the ATLAS inner tracker has to be upgraded to meet requirements in terms of radiation hardness, pile up and geometrical acceptance. The active edge technology allows to reduce the insensitive area at the border of the sensor thanks to an ion etched trench which avoids the crystal damage produced by

Integrated Active-Matrix Capacitive Sensor Using a-IGZO TFTs for AMOLED
IEEE Journal of the Electron Devices Society, 2018 We report a capacitive touch sensor using a-IGZO TFTs as active components to improve touch sensitivity and output robustness. The output potential difference between touched/untouched states is 1.7 V without readout buffer.
