Abstract
The MOST (Monolithic Stitched Sensor with Timing) is a 26 cm long wafer-scale pixel sensor prototype that bridges generic R&D for future High Energy Physics (HEP) detectors with the developments aimed for the ALICE Inner Tracking System (ITS3). Its main purpose is to investigate the yield of high-density pixel architectures, assess the timing capabilities of asynchronous readout, investigate an alternative sensor biasing scheme, evaluate yield enhancing power segmentation and verify a robust bias distribution method resilient to fluctuations of supply voltages. This contribution presents both the design overview of the MOST chip and key measurements that validate its functionality and performance.
