Journal ArticleDOI
High-Q bulk-mode SOI square resonators with straight-beam anchors
Lynn Khine,Moorthi Palaniapan +1 more
TL;DR: In this article, the performance of 6.35 MHz Lame-mode square resonators with different dimensions of straight-beam anchor supports is presented, with quality factor values exceeding one million in ambient pressures as high as 150 Pa.
Journal ArticleDOI
Characterization of nanomechanical graphene drum structures
TL;DR: In this article, an analytical framework was formulated to model the deflection behavior which was verified through finite element simulations (FEM) and the experimental measurements agree well with analytical and finite element results using Young's modulus of 1 TPa.
Journal ArticleDOI
The nonlinearity cancellation phenomenon in micromechanical resonators
TL;DR: In this paper, a nonlinear model which incorporates both mechanical and electrostatic nonlinear effects is established for the resonator and verified by experimental results, and the results from the clamped-clamped beam resonator studied in this work can be easily generalized and applied to other types of resonators.
Journal ArticleDOI
A CMOS Readout Circuit for SOI Resonant Accelerometer With 4- $\mu \rm g$ Bias Stability and 20- $ \mu\rm g/\sqrt{{\hbox{Hz}}}$ Resolution
TL;DR: A fully differential CMOS readout circuit for SOI resonant accelerometer and a differential sense resonator is proposed to facilitate fully differential circuit topology and improves the SNR under a 3.3-V supply.
Journal ArticleDOI
Elastic and nonlinear response of nanomechanical graphene devices
TL;DR: In this paper, a simple and effective experimental approach has been used to extract the mechanical properties of suspended nanomechanical graphene devices using atomic force microscopy (AFM), and the main objective of this work is to study the deflection behaviour of graphene devices as a function of layer number (1−5 layers) and anchor geometry.
