Gate‐Programmable Linearization of Atomically Thin Nanoelectromechanical Resonators via Duffing Nonlinearity Cancellation

Advanced Functional Materials, EarlyView.
Gate bias is used to cancel Duffing nonlinearity in atomically thin MoS2 drumhead resonators, switching their response from hardening to softening and creating a nearly linear operating point. This electrical control suppresses hysteresis, enables stronger linear drive, and improves signal‐to‐noise ratio, offering a practical route to stable 2D NEMS ...

Analysis of a Novel Soft-Switching DC–DC Converter for Reduction in Switching Loss

Power Electronics and Drives
The conventional buck converter is the first and foremost member among the family of DC–DC converters. Major drawback of the conventional buck converter is the hard-switching that leads to many shortcomings and finally leads to poor efficiency.
