Abstract

A 32 channel analog VLSI detector readout chip (HARP32) with an input charge preamplifier, a 64-cell current integrating analog memory in each channel and a common analog multiplexer, has been used in a test beam with segmented silicon detectors. The device was operated at the LHC clock speed of 66 MHz. The different pedestal variations seen at the output are analyzed: the input noise σ_n amounts to 2.8mV r.m.s., the pedestal non-uniformity in channel σ_ped to 1.2 mV r.m.s., the channel to channel pedestal variation σ_ch to 4.0 mV r.m.s., and an output baseline shift σ_obs of 3.5 mV r.m.s has been observed
