首先介绍了延迟积分电荷耦合器件（TDICCD）的基本原理，并根据某高分辨率多光谱航天相机定制的一款五光谱TDICCD的输出特性，设计了一种基于五光谱TDICCD的模拟信号发生器，给出了该模拟信号发生器的系统组成，包括图像处理电路、数模转换电路和模拟信号滤波电路。最后通过测试验证了该系统的信号波形、信号噪声和输出图像都满足设计要求，其输出的16通道模拟五光谱TDICCD信号频率可以达到20MHz，噪声控制在10mV以内，具有高精度、多通道和低噪声等特点。目前该模拟信号发生器已成功应用到新一代高分辨率多光谱TDICCD相机成像电路系统的研制中。

The paper introduces the principle of TDICCD firstly, and then designs an analog signal generator based on five-spectral TDICCD, according to the output characteristic of five-spectral TDICCD customized by a high resolution multi-spectral TDICCD camera. Analog signal generator consists of image processing circuit, digital-to-analog conversion circuit and analog signal filter circuit. Finally, verified by the system of signal, signal to noise ratio and the output images meet the design requirements. The system has the characteristics of high precision, multi-channel and low noise, whose 16 channels can analog five-spectral TDICCD signal frequency up to 20MHz and the signal to noise ratio is less than 10mV. The analog signal generator has been successfully applied in the development of imaging circuit system of the new generation high resolution multi-spectral TDICCD camera.
