An Ultra-high Resolution Resonant MEMS Accelerometer
Published in IEEE Conference on Microelectromechanical Systems, 2019, 2019
Abstract
This paper shows the first implementation of a micro-fabricated resonant accelerometer with a noise floor of 17.8ng/Hz1/2 and a bias stability of 17.5ng with a differential frequency readout configuration. The differential readout scheme provides for rejection of common mode environmental effects to first order. This prototype sensor demonstrates the best bias stability and noise floor of all MEMS resonant accelerometer configurations reported till date.
