Results of silicon strip detector readout using a CMOS low power microplex (MX1)

A system for reading out silicon strip detectors has been fabricated on a CMOS integrated circuit. The chip consists of an array of 128 amplifiers with a single multiplexed output. These chips have been bonded to a 256 channel silicon strip detector. Results are reported on the electrical parameters of the chips and on data taken during exposure of the instrumented detectors to minimum ionising beta particles. The radiation tolerance of the device has been investigated
