Study on Noise and Suppression of Readout Circuit for UV Focal Plane Array

Abstract The noise characteristics of readout circuit for ultraviolet focal plane array are analysed in this paper. And the restraining method of noise with correlated double sampling circuit is discussed. In order to verify the principle, a 64×1 line readout circuit is designed. The results show that the total noise is effectively restrained by applying the correlated double sampling circuit.
