Abstract :
The front-end system of the Silicon Drift Detectors (SDDs) of the ALICE experiment is made of two ASICs. The first chip performs the preamplification, temporary analogue storage and analogue-to-digital conversion of the detector signals. The second chip is a digital buffer that allows for a significant reduction of the connections from the front-end module to the outside world. In this paper, the architecture of the system is described and the results achieved on a first prototype are presented.
