1por Voulgari, Evgenia, Noy, Matthew, Anghinolfi, Francis, Krummenacher, Francois, Kayal, Maher“…An Application Specific Integrated Circuit (ASIC) able to digitize current generated from ionization chambers was designed and characterized in order to be used as the front-end of the new radiation monitoring system at CERN. The design of the Utopia 2 ASIC was motivated by the need to measure input currents as low as 2 fA and over a wide dynamic range of 9 decades. …”
