摘要
本文介绍了一种具有全局电子快门和12b列并行循环a /D转换器的高速CMOS图像传感器。该芯片采用0.25 μ m CMOS成像技术,实现了超过3500帧/秒的全帧速率。像素内电荷放大器实现了19.9V/lx的光学灵敏度和60dB的动态范围
A 3500fps High-Speed CMOS Image Sensor with 12b Column-Parallel Cyclic A/D Converters
This paper presents a high-speed CMOS image sensor with a global electronic shutter and 12b column parallel cyclic A/D converters. The fabricated chip in 0.25mum CMOS imager technology achieves the full frame rate in excess of 3500 frames per second. The in-pixel charge amplifier achieves the optical sensitivity of 19.9V/lx middot s and the dynamic range of 60dB
