However, various small currents that come with it will also have an increasing impact, among which the most common is dark current.Dark current refers to the tiny current generated due to the internal reasons of the electronic device when no voltage or current is applied to the electronic device. It can reduce the sensitivity of the device and cause bias and distortion, which has a great impact on practical applications.In this paper, a digital decompression system is proposed mainly to eliminate the influence of dark current. The system 精品文档---下载后可任意编辑adopts a digital filter to filter out the dark current signal by removing the high-frequency components in ...
