Commissioning of Pixel Sensor Telescope for Monolithic Active Pixel Sensor Characterization

Journal of Physics: Conference Series, 2023
Abstract The Monolithic Active Pixel Sensors (MAPS) have been promisingly demonstrated as a core part of tracking detectors used in many experiments. In order to obtain decent particle tracks generated after high-energy particle collision, it is especially important that the detector must consist of high-performance MAPS.

DEPFET Active Pixel Sensors

, 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 ...

Ambient Light Rejection Integrated Circuit for Autonomous Adaptation on a Sub-Retinal Prosthetic System

Sensors, 2021
This paper introduces an ambient light rejection (ALR) circuit for the autonomous adaptation of a subretinal implant system. The sub-retinal implants, located beneath a bipolar cell layer, are known to have a significant advantage in spatial resolution ...

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

Averaging Pixel Current Adjustment Technique for Reducing Fixed Pattern Noise in the Bolometer-Type Uncooled Infrared Image Sensor

Sensors, 2019
In this paper, we propose an averaging pixel current adjustment technique for reducing fixed pattern noise (FPN) in the bolometer-type uncooled infrared image sensor. The averaging pixel current adjustment technique is composed of active pixel, reference

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.
