Architecture for Integrated Mems Resonators Quality Factor Measurement
H. Mathias, F. Parrain, J. -P. Gilles +4
In this paper, an architecture designed for electrical measurement of the quality factor of MEMS resonators is proposed. An estimation of the measurement performance is made using…
Noise and thermal stability of vibrating micro-gyrometers preamplifiers
R. Levy, A. Dupret, H. Mathias +4
The preamplifier is a critical component of gyrometer's electronics. Indeed the resolution of the sensor is limited by its signal to noise ratio, and the gyrometer's thermal stabil…
Mems Q-Factor Enhancement Using Parametric Amplification: Theoretical Study and Design of a Parametric Device
L. Grasser, H. Mathias, F. Parrain +2
Parametric amplification is an interesting way of artificially increasing a MEMS Quality factor and could be helpful in many kinds of applications. This paper presents a theoretica…
Characterization of Flexible RF Microcoil Dedicated to Surface Mri
M. Woytasik, J. -C. Ginefri, J. -S. Raynaud +8
In Magnetic Resonance Imaging (MRI), to achieve sufficient Signal to Noise Ratio (SNR), the electrical performance of the RF coil is critical. We developed a device (microcoil) bas…
