Abstract

Scientific grade Charge Coupled Device(CCD) is widely used in astronomical telescope as imaging sensor at present. A CCD camera based on CCD driving and readout ASIC is designed using CCD47-20 in this paper. The CCD driving and readout ASIC chips include CCD drive chip BCDA2(Second Edition Bias Clock Driver ASIC) and CVRA2（Second Edition CCD Video Readout ASIC). BCDA2 provides multichannel clock and bias voltage for CCD. CVRA2 processes the output signal of CCD by correlated double sampling double slope integral. The processed signals will be sampled by external ADC. Based on the BCDA2 and CVRA2, the electronics system of the camera is designed including a Connecting Board, a pre-amp board and a master control board with CCD driver and CCD readout. The test result shows it’s working well.
