Design of Electronic Circuits for an Astronomical CCD Camera

This CCD camera is developed for astronomical image acquisition under remote control.This paper first briefly describes the system requirement of the CCD camera.The outlines of design and basic structure of the analog circuit and digital controller are subsequently presented in detail.These include the CCD peripheral circuit, the analog front end, the clock driver, the power supply, and the clock timing generator programmed with VHDL in FPGA.The simulation and testing results for some of the key components are presented and analyzed.Finally two images taken by the CCD Camera are shown.
