    Article
    Open Access
    This study analyzes the effects of the punch-through stop (PTS) layer and well depth in a bulk FinFET SRAM cell on the fraction of charge generated by an ion impact that is collected by the FinFET channel. More than 1700 ...
  • Piecewise linearization of quadratic transfer characteristics 

    Pallàs-Areny, Ramon (2022-05-19)
    Research report
    Open Access
    Piecewise linearization replaces a nonlinear transfer characteristic curve by a string of linear segments that connect several calibration points of the curve. This technique can be implemented by low-power digital ...

    Article
    Open Access
    Small-signal models are the mostly used to model and design in inverter-dominated microgrids. Conversely, this paper proposes a large-signal model for grid-forming inverters connected to a microgrid based on the active and ...
