The CBM-STS front-end electronics — •Adrian Rodriguez Rodriguez for the CBM collaboration — GSI Helmholtzzentrum fur Schwerionenforschung GmbH

The Silicon Tracking System (STS) of the CBM experiment is based on double-sided silicon microstrip sensors, arranged in 8 tracking stations. It poses the most demanding requirements in terms of readout rates and electronics density of all CBM detectors. The STS-XYTER is a 128 channel, low power, self triggering ASIC which provides timing and energy information for each hit sensor strip. One of the main goals on the chip design is to achieve a low level noise performance (below 1000 e⁻ rms). The first version of the chip has been tested and characterized in prototype front-end board. The second version of the ASIC is under revision to be submitted in early 2016. An overview of main tests outcomes and an outlook on version 2 will be presented.
