The FARCOS frontend electronics.
Castoldi A., Guazzoni C., Parsani T. per la Collaborazione FARCOS
In 2017 the first telescopes of FARCOS (Femtoscope ARray for COrrelation and Spectroscopy) will be fully instrumented. Each telescope has 132 readout channels (128 for the Si layers and 4 for CsI(Tl)). The frontend specs are extremely demanding especially in terms of dynamic range and energy resolution. The core of the frontend is the multi-channel charge preamplifier developed in AMS 0.35 $\mu$m technology. A dedicated frontend board houses 2 ASICs and the differential line-drivers to drive the several-meter--long connections. The talk describes the architecture and the performance of the frontend with focus on the experimental qualification of the dynamic range.
