GASTONE64: A new front-end ASIC for the cylindrical GEM Inner Tracker of KLOE-2 experiment at DAΦNE

摘要

GASTONE64 (Gem Amplifier Shaper Tracking ON Events) is a novel 64-channel mixed analog-digital ASIC developed to readout the cylindrical GEM inner tracking detector of the KLOE-2 apparatus at the e~+e~-DANE collider. It has been designed in the CMOS 0.35 μm technology and each analog channel is made of preamplifier, shaper and discriminator. The expected input charge ranges between few fC up to 40 fC, the charge sensitivity is 16 mV/fC while the equivalent input noise charge (ENC) is 800 e~-+40 e~-/pF. The discriminated signals are read-out using a 100 Mbit/s LVDS serial data link. The power consumption is about 6 mW/channel.
