Abstract :
We present our experience in design, construction, testing and operation of the frontend electronics (FEE) for the LPS silicon strip detectors for HERA. A total of about 22 000 channels has been operated as close as the 10σ envelope of the 820 GeV proton beam. This FEE system is binary, controlled by one threshold set at about 0.8 fC, and has been optimized by combining a fast low-noise bipolar amplifier/comparator VLSI with a low-power digital pipeline manufactured in radiation-hard CMOS.
