✦ Synopsis
For the full exploitation of the excellent timing properties of the Multigap Resistive Plate Chamber (MRPC), frontend electronics with special characteristics are needed. These are (a) differential input, to profit from the differential signal from the MRPC (b) a fast amplifier with less than 1 ns peaking time and (c) input charge measurement by Time-Over-Threshold for slewing correction. An 8-channel amplifier and discriminator chip has been developed to match these requirements. This is the NINO ASIC, fabricated with 0:25 mm CMOS technology. The power requirement at 40 mW/channel is low. Results on the performance of the MRPCs using the NINO ASIC are presented. Typical time resolution s of the MRPC system is in the 50 ps range, with an efficiency of 99:9%.
