一、引言 电荷耦合器件简称 CCD。首次发表于1970年3月,发明人是美国贝尔电话实验室的 W.S.Boyle 和 G.E.Smith。CCD 的出现是70年代电子学的一项重大进展,其工作原理和概念完全不同于过去建立在电压和电流调制理论上的所有有源器件。因此,有人认为它是电子学的第五代,即属于“分子电子学”领域的功能器件。正因为如此,它一出现就引起世界各主要国家电子科学界的普遍重视,短短几年内 CCD 便从实验室阶段进入了定型生产,并在具体应用中得到了突飞猛进的发展。用途主要有三个方面:成象、存储、模拟信号处理。由于
I. Introduction Charge Coupled Device referred to as CCD. First published in March 1970, inventor W.S. Boyle and G.E. Smith of Bell Telephone Laboratories in the United States. The advent of the CCD was a major advance in electronics in the 1970s and its working principle and concept was completely different from all the active devices that were built on the theory of voltage and current modulation in the past. Therefore, some people think it is the fifth generation of electronics, which belongs to the field of molecular electronics functional devices. Because of this, it has caused widespread attention of the electronic science community in all major countries in the world. In just a few years, the CCD has entered the stereotype production from the laboratory stage and has been rapidly developed in specific applications. There are three main uses: imaging, storage, analog signal processing. due to
