Abstract

Some astronomical telescopes require very small and light CCD camera. To satisfy this requirement, we develop a minimal electronics system for CCD controllers based on the two ASICs: SPA-2ch and CDA which are developed by the CCD Laboratory of NAOC. Layout the circuit that most affects the CCD noise index into a circuit board with the same area as the CCD sensor, pressing closely behind the CCD sensor. This circuit can be used in a low environment with CCD sensors, minimizing the overall volume of the camera. This system can support any full-frame CCD work with no more than 16 channels. In order to verify the solution, we designed a camera test system using CCD42-40. We report here on the design and performance of the minimal electronics system in details.
