Description
The CMS experiment will enhance its capabilities with precision timing detectors covering |η| ≤ 3 to manage high rates and reduce pile-up in the HL-LHC era starting in 2030. Future upgrades may extend timing across the full tracker acceptance (|η| ≤ 4), with LGADs as a potential option for pixel detector end-cap replacements. This project focuses on the development of an ASIC in 28 nm CMOS technology, optimized for TI-LGAD sensors, capable of achieving sub-30 ps timing resolution. Key features include a low-jitter preamplifier, a discriminator stage, and a Time-to-Digital Converter (TDC), with radiation tolerance up to 1-5 × 10¹⁵ neq/cm².
The ASIC design will balance performance, power efficiency, and integration while addressing HL-LHC challenges. Initial prototypes will feature a limited number of channels for systematic testing of timing resolution and radiation hardness. Successful designs will scale to full-channel ASICs compatible with various LGAD types, ensuring flexibility for future sensor developments.
Fabrication will occur via MPW/mini@sic runs, with testing in realistic radiation environments. Results will support the CMS Tracker upgrade, contribute to advancements in 4D tracking technologies, and enable future high-energy physics experiments.
