      abstract     = {Monolithic Active Pixel Sensors (MAPS) are candidates to
                      serve as vertex and tracking detectors in the future lepton
                      colliders. This is due to the many advantages they provide
                      compared to hybrid sensors, such as a reduced material
                      budget and lower power consumption. The TANGERINE project
                      aims for the development of the next generation of
                      monolithic silicon pixel sensors produced in the 65 nm
                      imaging process and investigates their possible use as
                      vertex detectors in future lepton colliders. To investigate
                      the 65 nm imaging process, simulations are implemented to
                      reproduce the sensor response and thus save time and
                      resources during the development phase. Technology
                      Computer-Aided Design (TCAD) simulations permit the
                      production of complex electric field profiles by the use of
                      generic doping concentrations, a solution to the restricted
                      access that commercial foundries implement in their
                      fabrication process. A combination of Monte Carlo (MC)
                      simulations using electrostatic TCAD fields was introduced
                      to address the intensive computational requirements of using
                      transient TCAD simulations. This allows the utilization of
                      realistic electric fields combined with a high particle
                      rate, resulting in simulations with high statistics.
                      Furthermore, to include the effects that the electronics
                      have on the signal produced by the silicon detector,
                      Simulation Program with Integrated Circuit Emphasis (SPICE)
                      is integrated into the simulation chain. The sensors used
                      for the validation of the simulation chain are the ALICE
                      Analogue Pixel Test Structure (APTS) are MAPS produced in a
                      65 nm CMOS imaging process designed at CERN for the CERN EP
                      $R\&D$ program and are part of the studies for the ALICE
                      ITS3 upgrade. In particular, the Analogue Pixel Test
                      Structure Source Follower (APTS-SF) allows for the study of
                      the different layouts and their effect on the signal due to
                      several source follower stages used a simple electronic
                      readout. This work showcases the results of a simulation
                      approach combining TCAD, MC, and SPICE, a comparison of
                      charge studies of these simulations with MAPS using a Fe-55
                      source for calibration and measurements taken at the DESY-II
                      test beam facility using a 4 GeV electron beam. A discussion
                      of the highlights and discrepancies between simulation and
                      experimental data, and the possible reasons for these
                      disagreements, is presented.},
