摘要:
Microelectromechanical systems (MEMS) gyroscopes and related sense frequency tracking techniques are described. Various embodiments facilitate sense frequency tracking and offset and/or sensitivity change compensation. Exemplary embodiments can comprise receiving a sense signal at an output of a MEMS gyroscope and determining a sense resonant frequency of the sense signal. In addition, exemplary methods can comprise generating an input sine wave with a frequency of the sense resonant frequency of the sense signal injecting the input sine wave into the MEMS gyroscope, to facilitate sense frequency tracking.
