转发：随着产品发展（主要是佳能的进步），现在已经不用和大家再科普“片上ADC”这个概念了……
CMOS虽然属于数字电路，但它输出的是模拟信号。需要通过模数转换器（Analog to Digital Converter，简称ADC）才能转换为图像处理器可以接收的数字信号。
2007年，索尼发布了“Column-Parallel A/D Conversion Technique”列并行AD转换技术以及最先搭载此技术的产品IMX021。不仅具有高速数据读取（12bit 12.47MP 10.39fps），同时还能通过CDS降低噪声。而这让索尼CMOS的动态范围表现一跃超过其他竞争对手。
在今天，绝大多数CMOS都采用片上ADC设计

A friend asked me why I want to delete the published news
I think maybe I wanted to vent my emotions at that time. The next day, I will feel so bad. Therefore, I always publish it in the evening and delete it in the morning, because I don't want to be noticed and become the conversation capital of others. As long as your emotions are vented, don't disturb others
