Microelectromechanical 2-Bit Logic Device via Frequency Comb Generation

The paper introduces a 2-bit logic device capable of executing all fundamental 2-bit logic operations, such as NOT, NOR, OR, AND, NAND, XOR, and XNOR, utilizing a microelectromechanical resonator with frequency comb generation. Despite the growing interest in phononic frequency combs (PFCs), their practical applications have been underexplored. This work highlights a potential application in logical operations, where pump signals act as logic inputs. The resonator is fabricated using standard silicon-on-insulator technology, making it suitable for integration into on-chip systems.
