Characterization of Thin p-on-p Radiation Detectors with Active Edges

, 2016
Active edge p-on-p silicon pixel detectors with thickness of 100 $\mu$m were fabricated on 150 mm Float zone silicon wafers at VTT. By combining measured results and TCAD simulations, a detailed study of electric field distributions and charge collection

Frame-transfer CMOS active pixel sensor with pixel binning

IEEE Transactions on Electron Devices, 1997
The first frame-transfer CMOS active pixel sensor (APS) is reported. The sensor architecture integrates an array of active pixels with an array of passive memory cells. Charge integration amplifer-based readout of the memory cells permits binning of pixels for variable resolution imaging.

Energy calibration through X-ray absorption of the DECAL sensor, a monolithic active pixel sensor prototype for digital electromagnetic calorimetry and tracking

Frontiers in Physics, 2023
In calorimetry, the predominant detection principle is to measure the energy deposited by particles within a shower initiated by an incident particle. An alternative concept is a sampling calorimeter where the highly granular active layers rather measure

Simulation of CMOS APS Operation and Crosstalk in SPICE With Generalized Devices

IEEE Journal of the Electron Devices Society, 2020
We present SPICE simulations of a CMOS APS pixel element consisting of the optical sensor with the sensing circuit. The photodiode is simulated at the physics level by means of the so-called Generalized Devices, without any predefined compact model ...

Improving light collection efficiency using partitioned light guide on pixelated scintillator-based γ-ray imager

Nuclear Engineering and Technology, 2022
When gamma-camera sensor modules, which are key components of radiation imagers, are derived from the coupling between scintillators and photosensors, the light collection efficiency is an important factor in determining the effectiveness with which the ...
