A 36-channel silicon-photomultiplier readout integrated circuit for high granular imaging calorimetry — •Zhenxiong Yuan for the CALICE-D collaboration — Im Neuenheimer Feld 227, Heidelberg 69120, Germany

KLauS5 is a 36-channel mixed-mode silicon-photomultiplier (SiPM) charge readout integrated circuit dedicated to the high granular imaging calorimetry at future linear collider. Due to the high granularity and dense structure of the calorimeter system, one of the key aspects for its readout electronics is ultra-low power consumption. This application specified integrated circuit (ASIC) is designed to read out the SiPM charge information with high precision and over large dynamic range. Each channel consists of a low-noise front-end with two gain branches to deal with a large input signal range, and a 10/12-bit ADC to digitize the charge information; a common digital part for data storage and transmission is also implemented into this chip. The design of the ASIC and results of the characterization measurements will be presented.
