摘要: We describe a novel amplification scheme based on inducing dynamical changes to the topology of bifurcation diagram simple nonlinear system. have implemented first bifurcation-topology amplifier using coupled pair parametrically driven high-frequency nanoelectromechanical systems resonators, demonstrating robust small-signal amplification. The principles that underlie are and generic, suggesting its applicability wide variety physical, chemical, biological systems.
