CMOS active pixel image sensor

IEEE Transactions on Electron Devices, 1994
A new CMOS active pixel image sensor is reported. The sensor uses a 2.0 /spl mu/m double-poly, double-metal foundry CMOS process and is realized as a 128/spl times/128 array of 40 /spl mu/m/spl times/40 /spl mu/m pixels. The sensor features TTL compatible voltages, low noise and large dynamic range, and will be useful in machine vision and smart sensor

Locally adaptive active pixel sensors

Proceedings of 1997 IEEE International Symposium on Circuits and Systems. Circuits and Systems in the Information Age ISCAS '97, 2002
In this paper we describe two circuits for implementing local adaptation in active pixel sensors. In addition to increasing the dynamic range, local adaptation provides finer resolution. The first photoreceptor circuit consists of an active pixel sensor which is operated at three different shutter speeds given sequentially. The decision to use the next

A Novel One-Transistor Active Pixel Sensor With In-Situ Photoelectron Sensing in 22 nm FD-SOI Technology

IEEE Electron Device Letters, 2019
For the first time, a novel active pixel sensor (APS) with 22 nm fully depleted silicon-on-insulator (FD-SOI) technology is experimentally demonstrated. The APS in-situ integrates photo sensing, charge integration, buffer amplification, and random access

Adaptive multiple resolution CMOS active pixel sensor

2004 IEEE International Symposium on Circuits and Systems (IEEE Cat. No.04CH37512), 2004
A smart image sensor with adaptive multiple resolution ability is presented. This sensor is based on the quadtree decomposition algorithm, which decomposes an image into square homogeneous regions. After the image is segmented, only the value of the block and its size are stored or transmitted.

High-dynamic-range active pixel sensor

SPIE Proceedings, 2004
A new pixel structure for high dynamic range imaging is proposed. The internal pixel circuit resets the pixel each time the well capacity nears saturation and a counter, implemented in the pixel itself (or in an external memory), records the number of resets per integration time. The increase in the dynamic range is given by a factor of (m + 1) where m

Active Pixel Sensors for electron microscopy

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2007
The technology used for monolithic CMOS imagers, popular for cell phone cameras and other photographic applications, has been explored for charged particle tracking by the high-energy physics community for several years. This technology also lends itself to certain imaging detector applications in electron microscopy.

Radiation effects on active pixel sensors

1999 Fifth European Conference on Radiation and Its Effects on Components and Systems. RADECS 99 (Cat. No.99TH8471), 2003
An active pixel sensor (APS) is defined as a CMOS detector array that has at least one active transistor integrated into the pixel. Two kinds of detector arrays were used: one photodiode and one photogate. Their tolerance against total dose and proton irradiations are evaluated.

High Voltage Monolithic Active Pixel Sensors

Nuclear Physics News, 2018
Ever higher demands on resolution and rate capability drive the development of particle tracking detectors. Especially at low momenta, multiple Coulomb scattering in the material of the detector is also strongly affecting the resolution of momentum measurements.
