Description
SPIROC (SiPM Integrated Read Out Chip) is the Very Front End ASIC that reads ILC
hadronic calorimeter SiPM. It integrates a very complex digital part which performs
many functions and manages Acquisition, A/D Conversion and data Read-out.
The Acquisition module manages Switched Capacitor Array in which charge and time are
stored. This is done by an asynchronous module to meet time requirements. This part
manages 36 channels with a depth of 16 for each.
The conversion step permits to convert analogue data into digital data by driving an
integrated Wilkinson ADC. Data are stored into an integrated 4K bytes memory.
The read out step handles the communication between chips and sendout of data. ASIC
are daisy chained to minimize lines between boards.
