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-ionizing beta particles. The radiation tolerance of the device has been investigated. The MX1 is working to specification and is presently being incorporated into equipment.<
