摘要： In one embodiment, a micro-gyro device for measuring rotational movement about an input axis includes a driving element generating a driving signal. A MEMS gyro includes a motor rotor and a motor assembly. The motor rotor receives the driving signal and oscillates about a motor axis at a frequency determined as a function of the driving signal. The motor assembly oscillates around a rate axis, which is orthogonal to the motor axis, as a function of the frequency of the motor rotor oscillation. A capacitance of the motor assembly changes as a function of the oscillation of the motor assembly. Driving element feedback circuitry, including a first band-pass filter, is between the motor rotor and the driving element. The driving element feedback circuitry causes the driving element to generate the driving signal as a function of an amplitude of the motor rotor oscillation for maintaining the amplitude of the motor rotor oscillation within a predetermined range. Output circuitry, including a second band-pass filter, produces an output signal as a function of the changing capacitance of the motor assembly. The first and second band-pass filters have central frequency phase characteristics not exceeding about 0.1°/Hz.
