Development of low noise CCD readout front-end

Abstract

This paper describes development of low noise readout subsystem for digital camera dedicated for astronomical observations. Main aim of the study is noise reduction in regard of sensor's output signal and noise added by the analogue electronics. Basic concept and simulation results of analogue front-end are presented. Various Digital Signal Processing schemes are considered in order to increase Signal to Noise ratio. Another step of development are design of the prototype PCB board and implementation of selected processing techniques in to the structure of a FPGA device.
