Abstract

The CALOROC1B ASIC has been designed to read out the SiPMs for the ePIC detector at the EIC collider. Each of its 36-channels is composed of a high-gain preamplifier, two low-power preamplifiers, a dynamic gain switching mechanism, a shaper, and two ADCs to measure the energy, with a discriminator connected to a TDC for time-of-arrival measurements. This work presents the ASIC architecture and its simulation results. The ASIC has been designed to read large SiPMs (up to 10 nF), be resilient to radiation, and have a large dynamic range (up to 140k measured as Qmax/Noise) while keeping a good resolution.
