摘要: We investigate the synchronization of oscillators based on anharmonic nanoelectromechanical resonators. Our experimental implementation allows unprecedented observation and control parameters governing dynamics synchronization. find close quantitative agreement between data theory describing reactively coupled Duffing resonators with fully saturated feedback gain. In synchronized state we demonstrate a significant reduction in phase noise oscillators, which is key for sensor clock applications. work establishes that oscillator networks constructed from nanomechanical form an ideal laboratory to study synchronization— given their high-quality factors, small footprint, ease cointegration modern electronic signal processing technologies.
