Abstract

The mixed-signal PRIMA-chip has been developed for sensitive-position silicon detector in proton imaging application. The chip is based upon the binary readout architecture which, providing fully parallel signal processing, is a good solution for high intensity radiation application. It includes 32-front-end channels with a charge preamplifier, a shaper and a comparator. In order to adjust the comparator thresholds, each channel contains a 8-bit DAC, programmed using an I2C like interface. The PRIMA-chip has been fabricated using the AMS 0.35 μm standard CMOS process and its performances have been tested coupling it to the detectors used in the tracker assembled for the pCT (proton Computed Tomography) apparatus.
