AB  - Digital Silicon Photomultipliers (dSiPMs) and Monolithic Active Pixel Sensors (MAPS) are emerging technologies, fabricated using commercial Complementary Metal-Oxide-Semiconductor (CMOS) processes. These detectors have the potential to become key components in High-Energy Physics (HEP), with the ability to meet the demanding requirements of future experiments. The first part of the thesis analyzes the DESY dSiPM prototype as an example of the technology potential. Extensive laboratory characterizations confirm the functionality of the sensor and of all integrated CMOS circuitry. Sensor calibrations ensure stable and controlled operation enabling the study of prototype performance by offering an in-depth understanding of the sensor’s capabilities. The performance of the prototype in Minimum Ionising Particles (MIP) detection is evaluated through beam tests at the DESY II test-beam facility. The measurements aim to establish the potential use of this technology in 4D-Tracking of charged particles. The bare DESY dSiPM in MIP detection shows a spatial resolution of 20 µm, a time resolution of 50 ps with an efficiency of about 30
