Analog device of external synchronous time-delayed-integration charge coupled device

External synchronous delay integration charge coupled device belonging TDI CCD field simulation apparatus, the apparatus comprising: an analog circuit pin electrical characteristics, feature extraction circuit driver, the OS signal synthesizing circuit, a delay characteristic of the control circuit, the control circuit and the integral sensitivity stages the control circuit; TDICCD present invention achieves actual dimensions, electrical characteristics of input and output pins, and an analog output video signal characteristic of the photosensitive pair. This device uses the external synchronous principle realized analog TDI CCD signal, this means the actual dimensions and TDI CCD dimensions relatively, and has a simple structure, low cost, it can completely replace the actual TDI CCD completion of each kind of experimental work.
