Abstract

Abstract: The CROCv1 front-end (FE) chip was designed by the RD53 collaboration for the CMS Phase-2 Inner Tracker Upgrade. It is designed to cope with the extreme radiation and hit rates of the HL-LHC and it is based on the 65 nm CMOS technology and a novel analog FE design featuring linear charge to Time-over-Threshold conversion. In this contribution, the characterization measurements of the analog part of the chip are presented with a special focus on the linear analog FE, including Total Ionizing Dose radiation damage studies.
