High-speed VGA resolution CMOS image sensor with global shutter
SPIE Proceedings, 2012A 600 frames per second CMOS image sensor with 644 (H) x 484 (V) 7.4 μm 8-transistor global shutter pixels and digital outputs is described, consuming 300 mW. The global shutter pixel architecture supports correlated double sampling, resulting in a full well charge of 23,000 e-, a read noise of 12 e- RMS and a dynamic range of 65.6 dB. The sensor is

A 100dB dynamic range CMOS image sensor with global shutter
2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006A 100 dB dynamic range global shutter CMOS image sensor implementing an innovative fixed pattern noise (FPN) reduction method is presented. This image sensor uses global shutter pixel architecture in order to avoid distortion in imaging fast moving objects. To limit shutter leakage, a new PMOS pixel architecture is implemented.

CMOS image sensor with NMOS-only global shutter and enhanced responsivity
IEEE Transactions on Electron Devices, 2003Most CMOS image sensors today use the rolling shutter approach to control the integration time. This pixel architecture is advantageous where minimal pixel size is required to increase resolution or reduce over all chip size. For imaging of a fast moving object or when used with pulsed illumination, the rolling shutter approach is not suitable since it

An Autofocus Sensor With Global Shutter Using Offset-Free Frame Memory
IEEE Transactions on Circuits and Systems II: Express Briefs, 2010An autofocus (AF) sensor with global shutters using offset-free frame memory is presented. A cross-shaped AF sensor array has left and right horizontal arrays and top and bottom vertical arrays. AF is achieved by calculating the phase difference from the digital code of the light illumination difference between the left and right (or top and bottom ...

A fast global shutter image sensor based on the VOD mechanism
IEEE SENSORS 2014 Proceedings, 2014This paper presents a method to realize a fast and uniform global shutter for time resolved imaging in standard, commercially available image sensors. Fast toggling of the substrate voltage is used in image sensors with a Vertical Overflow Drain (VOD) shutter mechanism, a common building block of IT-CCDs.

Low Noise Global Shutter Image Sensor Working in the Charge Domain
IEEE Electron Device Letters, 2019In this letter, we present global shutter (GS) pixel using active deep trench isolation gate to transfer and store photodiode charge signal into a fully depleted pinned MOS capacitance. This architecture is compatible with conventional correlated double sampling. GS readout noise lower than 2e- is demonstrated.

A Wafer-Level Micro Mechanical Global Shutter for a Micro Camera
2009 IEEE 22nd International Conference on Micro Electro Mechanical Systems, 2009A novel wafer-level manufactured micro mechanical global shutter utilizing thin-film roll actuators is presented for a micro mobile camera. The aperture of the shutter is 2.2 mm in diameter and covered with 36 triangular roll actuators whose radius of curvature is designed to 235 ?m. The stress induced rolling of thin composite layers and their pull-in
