Abstract

In this paper,compared with the traditional CCD camera imaging circuits, a kind of integrated solution for CCD imaging circuits is put forward.The principle of the traditional CCD camera imaging circuits is described briefly, and the foundational functions are introduced. CCD imaging circuits are the most important parts of the CCD camera, and they are mainly made up of CCD driver circuits and CCD signal processing circuits. The CCD signal processing circuits mainly consist of timing generator, preamplifier circuits, CDS circuits, low-pass filter circuits, PGA circuits, ADC circuits, storage circuits, output interface circuits, and so on. The popular solution is that all the circuits are made with separate components.Complex circuit configuration, difficult debugging, uptight power dissipation are evident. However, it goes without saying that the integrated solutions which combine ADC with FPGA device are high integration, simple configuration and better agility. Finally, the integrated solution for CCD imaging circuits is illustrated, and the problems of the circuits are analyzed and summarized in detail.
