HARDROC3, a 3rd generation ASIC with zero suppress for ILC Semi Digital Hadronic Calorimeter
2017
HARDROC is the front end chip designed to read out the Resistive Plate Chambers foreseen for the Digital HAdronic
CALorimeter(DHCAL) of the future
International Linear Collider. The very fine granularity of the
calorimeterimplies thousands of electronics channels per cubic meter which is a new feature of "imaging" calorimetry. Moreover, for compactness, chips must be embedded inside the detector making crucial the reduction of the power consumption down to 12 μ W per channel. This is achieved using power-pulsing and online
zero-suppression. Around 800 HARDROC3 were produced in 2015. The overall performance and
production testswill be detailed.
