The Silicon micromachined gyroscope capacitance detection method as the mainsilicon micromachined gyroscope direction of many companies and research institutes at home and abroad .
For the capacitive silicon micromechanical gyroscope, mostly in the number of driver amplitude micron dizzy level, amplitude detection is more small, in this tiny amplitude, sensitive capacitance change in fF ~ aF category.In order to improve the capacitive silicon micromechanical gyroscope measurement precision, reduce the gyro zero drift, high signal-to-noise ratio of signal processing method is a particularly important.
This paper makes a study of the silicon gyro detection signal digital processing method. Particular way is by using the computer software matlab programming method to the micro mechanical silicon gyro closed loop drive signal, detection signal and demodulation signal digital filter.First is the use of matlab software to make the original signal waveform and spectrum，Secondly according to filter using matlab software requirements to design digital filter, and digital filter, draw the digital filter amplitude frequency characteristics of the figure and the filter signal waveform and spectrum diagram,compared to the waveform and spectrum before and after filtering，and finally determine the application of the final filter.
