      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.},
