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 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.
