Mode-Dependent Scaling of Nonlinearity and Linear Dynamic Range in a NEMS Resonator
M. Ma, N. Welles, O. Svitelskiy +5
Even a relatively weak drive force is enough to push a typical nanomechanical resonator into the nonlinear regime. Consequently, nonlinearities are widespread in nanomechanics and…

Phase-Locked Loop based Resonant Sensors: A Rigorous Theory and General Analysis Framework for Deciphering Fundamental Sensitivity Limitations due to Noise
Alper Demir, M. Selim Hanay
Nanomechanical resonators are used in building ultra-sensitive mass and force sensors. In a widely used resonator based sensing paradigm, each modal resonance frequency is tracked…
