, 2022 An array of DEPFET pixels is one of several concepts to implement an active pixel sensor. Similar to PNCCD and SDD detectors, the typically 0.45 mm thick silicon sensor is fully depleted by the principle of sideward depletion. They have furthermore in common to be back-illuminated detectors, which allows for ultra-thin and homogeneous photon entrance ...

Using an active pixel sensor in a vertex detector [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005 Research has shown that Active Pixel CMOS sensors can detect charged particles. We have been studying whether this process can be used in a collider environment. In particular, we studied the effect of radiation with 55 MeV protons. These results show that a fluence of about 2 x 10{sup 12} protons/cm{sup 2} reduces the signal by a factor of two while ...

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

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.

3D track reconstruction capability of a silicon hybrid active pixel detector
European Physical Journal C: Particles and Fields, 2017 Timepix3 detectors are the latest generation of hybrid active pixel detectors of the Medipix/Timepix family. Such detectors consist of an active sensor layer which is connected to the readout ASIC (application specific integrated circuit), segmenting the
