Abstract

In this paper we present an analog circuit for the new MIP Timing Detector of the CMS experiment at CERN, featuring, for the first time, a silicon implementation of the Differential Leading Edge Discriminating technique to suppress SiPM dark noise. This technique also stabilizes the baseline, leading to a time resolution of 25 ps at beginning of life and 55 ps at end of life while dissipating less than 4 mW. The full analog front-end ASIC has 32 channels and has been designed in a CMOS 130 nm technology with a total die area of 8.5 x 5.2 mm2. The radiation tolerance of this design has been confirmed by radiation tests.
