The features of the 180nm TowerJazz1 CMOS technology allow for the first time the use of CMOS Monolithic Active Pixel Sensors (MAPS) under the harsh operational conditions of the LHC experiments. The stringent requirements of the ALICE Inner Tracking System (ITS) in terms of material budget, radiation hardness, readout speed and a low power consumption have thus lead to the choice of MAPS as baseline...
The paper describes the design of a front-end chip for hybrid pixel detectors optimized for good timing resolution (200 ps rms) and high event rate (150 kHz per pixel). Each channel consists of a fast transimpedance amplifier with 5 ns peaking time, a constant fraction discriminator (CFD), and a Time-to-Digital Converter (TDC). In order to cope with the rate requirement, a multi-event buffering scheme...
