Paper Abstract

The paper analyzes the generated mechanism of the reset noise when reading out the CCD video signal. It also states a sampling technique for CCD output video signal, the Correlative Double Sampling (CDS) technique, which is on the basis of noises canceled-each-other and the mathematics correlative theory. The paper introduces the operation principle of the CDS technique and its filtering effects on the output noise of CCD (which includes the reset noise of CCD, the coupled cross-talk noise between the horizontal clock drive and the ground-wire of power supply, the white noise of output amplifier and the reset noise of 1/f noise). The paper gives a electric circuit of CDS that is applied practically. At last, it verified the conclusion that the output S/N of CCD signal can attain to 50dB.
