(2023). Future developments of radiation tolerant sensors based on the MALTA architecture. Journal of Instrumentation, 18(03), C03013.1748-0221http://dx.doi.org/10.1088/1748-0221/18/03/C03013https://hdl.handle.net/20.500.12491/11720Acknowledgments This project has received funding from the European Union?s Horizon 2020 Research and Innovation programme under Grant Agreement Numbers: 101004761, 675587215, and 654168.The planned MALTA3 DMAPS designed in the standard TowerJazz 180 nm imaging process will implement the numerous process modifications, as well as front-end changes in order to boost the charge collection efficiency after the targeted fluence of 1 x 1015 1 MeV neq/cm2. The effectiveness of these changes have been demonstrated with recent measurements of the full size MALTA2 chip. With the original MALTA concept being fully asynchronous, a small-scale MiniMALTA demonstrator chip has been developed with the intention of bridging the gap between the asynchronous pixel matrix, and the synchronous DAQ. This readout architecture will serve as a baseline for MALTA3, with focus on improved timing performance. The synchronization memory has been upgraded to allow clock speeds of up to 1.28 GHz, with the goal of achieving a sub-nanosecond on-chip timing resolution. The subsequent digital readout chain has been modified and will be discussed in the context of the overall sensor architecture.eninfo:eu-repo/semantics/openAccessDigital Electronic CircuitsElectronic Detector Readout Concepts (Solid-State)Particle Tracking DetectorsSolid State DetectorsArticle10.1088/1748-0221/18/03/C03013183172-s2.0-85150483659Q2WOS:000962506300009Q3
