Abstract

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 to 10 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.
