Design of a monolithic HR-CMOS sensor chip for the CLIC silicon tracker

The CLIC Tracker Detector (CLICTD) is a monolithic active pixel sensor targeted at the tracking detector of a future experiment at the Compact Linear Collider (CLIC). The chip features a matrix of 16×128 cells, each cell measuring 300×30 μm2. The cells are segmented in the long direction in order to maintain the benefits of the small collection electrode. In the digital logic, a simultaneous 8-bit Time of Arrival and 5-bit Time over Threshold measurement is performed. A 180 nm HR-CMOS Imaging Process was selected for the design of a chip that will meet the requirements of the tracker at CLIC. In this document, the CLICTD design and chip interface are presented.
