Noise analysis and characterization of a sigma delta capacitive silicon microaccelerometer

Noise analysis and characterization of a sigma-delta/capacitive microaccelerometer Külah, Haluk; Yazdi, N; Najafi, K (2006-02-01) This paper reports a high-sensitivity low-noise capacitive accelerometer system with one micro-g/root Hz resolution. The accelerometer and interface electronics together operate as a second-order electromechanical sigma-delta modulator. A detailed noise analysis of electromechanical sigma-delta capacitive accelerometers with a final goal of achieving sub-jig resolution is also presented. The analysis and test results have shown that amplifier thermal and sensor charging reference voltage noises are dominant...

Noise prediction of a transonic cavity flow via shear-layer-adapted delayed detached-eddy simulation Yalçın, Özgür; Özyörük, Yusuf (2018-01-01) © 2018 by the American Institute of Aeronautics and Astronautics, Inc. All rights reserved.An open cavity flow contains a highly turbulent shear layer which separates from the upstream edge and impinges on the aft wall of the cavity, causing intense noise emission. In this study, a delayed detached-eddy simulation (DDES) with the use of "shear-layer-adapted" subgrid length scale, an enhancement of DDES available in literature, is conducted for such an open cavity flow problem. The results show that this len...

Noise reduction using anisotropic diffusion filter in inverse electrocardiology. Gavgani, Alireza Mazloumi; Serinağaoğlu Doğrusöz, Yeşim (2012-01-01) Filtering has been widely used in biomedical signal processing and image processing applications to cancel noise effects in signals recorded from the body. However, it is important to keep the desired characteristics of the physiological signal of interest while suppressing the noise characteristics. In this study, we used anisotropic diffusion filter (ADF) to cancel the noise on the body surface potentials measurements (BSPM) with the goal of improving the corresponding solutions of the inverse problem of ...
