HADROC1: Readout chip of the digital hadronic calorimeter of ILC

HARDROC is a complete readout chip in SiGe 0.35μm of the RPCs or GEMs foreseen for a Digital HAdronic CALorimeter (DHCAL) at the ILC. The ASIC integrates 64 channels of : • Fast low impedance current preamplifier with 6 bits variable gain (tunable between 0 and 4) • Variable shaper (75-150ns) and Tr...

description HARDROC is a complete readout chip in SiGe 0.35μm of the RPCs or GEMs foreseen for a Digital HAdronic CALorimeter (DHCAL) at the ILC. The ASIC integrates 64 channels of : • Fast low impedance current preamplifier with 6 bits variable gain (tunable between 0 and 4) • Variable shaper (75-150ns) and Track and Hold to provide a multiplexed analog charge output up to 10pC. • Variable gain fast shaper (15ns) followed by two low offset discriminators to autotrig down to10 fC. The thresholds are loaded by two internal 10 bit- DACs. • A 128 deep digital memory to store the 2*64 discriminator outputs and bunch crossing identification coded over 24 bits counter. The design and measured performance of the chip will be presented.
