Abstract: Monolithic active pixel sensors (MAPS) are promising candidates for the next generation of vertex detectors at future lepton colliders. One particularly interesting advancement is the recently accessible 65 nm CMOS imaging technology, which offers higher logic density compared to larger feature-size processes, making it highly appealing to the High Energy Physics community. This paper highlights the progress made with prototypes, an analog test structure, DESY ER1, featuring a 2 × 2 active pixel configuration. The chip is integrated into the Caribou DAQ system, and detailed laboratory and test beam characterizations have been conducted. The DESY ER1 provides access to analog waveforms generated by the charge-sensitive amplifier with a Krummenacher feedback loop. The paper presents the initial testing results of DESY ER1 at sensor bias voltage of −3.6 V, including the charge calibration with Fe-55 and tracking performance characterization in test beam. The test beam measurements shows that the time resolution for detecting charged particles is below 8.72 ns at a threshold of 200 e.
