| 摘 要： | As a sampling technique for CCD output video signal, the correlated double sampling (CDS) technique is described as well as the filtering effects of the CDS technique on the output noise of CCD including the reset noise of CCD, the white noise of output amplifier and 1/f noise. From real application of CDS device TH7982A, it is concluded that the output signal-to-noise ratio of 50 dB for CCD signal can be obtained.
