HARDROC, HAdronic Rpc Detector ReadOut Chip

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 preamplifier with 6bits variable gain (tunable between 0 and 4) • variable shaper (50-150ns) 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 autotrigg 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.
