The performance of the latest prototype of the radiation hard front en
d chip to be used by the CMS collaboration for analogue readout of the
microstrip tracker has been evaluated with a silicon microstrip detec
tor in a beam at CERN. The circuit, developed by the RD20 collaboratio
n, consists of 128 channels of amplifier, pipeline memory, analogue si
gnal processor and a serial multiplexer. As a result of these studies
improvements in the circuit design have been devised which will be imp
lemented in the next version.
