A 1/1.7-inch 20Mpixel Back-Illuminated Stacked CMOS Image Sensor for New Imaging Applications

📋 论文概要

本文提出了一款1/1.7英寸20M像素背照式堆叠CMOS图像传感器，通过堆叠技术实现高分辨率、高速读出和低噪声，满足了慢动作拍摄和减少卷帘快门失真等新成像应用的需求。

💡 主要创新点

• 采用背照式堆叠结构，将像素层与逻辑电路层分开堆叠，实现了20M像素的高分辨率同时保持小芯片尺寸。
• 优化了像素设计和读出电路，实现了高速帧率（如60fps全分辨率），并降低了读出噪声，适用于低光照环境。

In addition, the emerging camcorder market typified by handsfree devices requires the simultaneous capture of still and moving images. To improve noise performance, a method of pseudo-multiple sampling has been proposed [1]. However, the noise reduction effect is insufficient due to the
