Hi,
Can anybody explain to me what the major noise issues are with mems closed loop accelerometers

Noise in closed loop accelerometers refers to unwanted or random fluctuations in the measured acceleration signal. It can be caused by various factors such as electrical interference, mechanical vibrations, or thermal noise.
Noise can significantly impact the accuracy of closed loop accelerometers by introducing errors in the measured acceleration values. This can make it difficult to distinguish the true signal from the noise, resulting in inaccurate readings.
Common sources of noise in closed loop accelerometers include electromagnetic interference from nearby electronic devices, mechanical vibrations from the surrounding environment, and thermal noise from the accelerometer itself.
Noise in closed loop accelerometers can be reduced by using shielding to minimize electromagnetic interference, using mechanical isolation to reduce vibrations, and implementing signal processing techniques to filter out noise.
Yes, the noise level in closed loop accelerometers can be measured using various techniques such as power spectral density analysis or root mean square (RMS) calculations. These measurements can help in identifying the sources of noise and implementing strategies to reduce it.
