Front-end electronics for readout of silicon tracker in the ATLAS experiment

The paper presents the front-end electronics for the readout of silicon strip detectors in the ATLAS experiment. A basic component of the system is a 128-channel ASIC which receives the signals from the detectors, performs signal processing, buffering and compression of data. We discuss critical issues of the design, like noise, radiation hardness and integration of analogue and digital circuits on the same integrated circuit. (11 refs).
