Abstract
A MEMS gyroscope includes a mixed analog and digital drive loop. A drive sense signal from a suspended spring-mass system is received by the drive loop, rectified, and compared to a reference signal. The result of the comparison is processed and converted into a digital signal that is processed by a digital filter and a digital pulse-width modulator of the drive loop. The output of the pulse width modulator controls a high-voltage drive of the drive loop that generates a drive signal having an amplitude based on the pulse width modulator output signal and supplies the drive signal to drive the suspended spring-mass system.
