Over 100Mfps high speed global shutter CMOS image sensor
Graduate School of Engineering, Tohoku University Abstract
In this talk, the progress of high speed global shutter CMOS image sensors development will be presented. By introducing the pixel-wise analog memory array and newly developed signal readout scheme, a frame period of photo-electrons transit time is achieved. The fabricated global shutter CMOS image sensor chip prototyping a 3D stacked structure achieved 125Mfps with 40 record length under room temperature without any cooling systems.
