DRIVE CIRCUITRY AND METHOD FOR A VIBRATION GYROSCOPE
Abstract:
A drive circuitry for a vibration gyroscope is described. The drive circuitry comprises a digital phase shifter, a variable gain amplifier and a pulse signal generator arranged to generate a digital pulse signal having a frequency substantially equal to a drive frequency of the vibration gyroscope. A controller is arranged to connect drive actuation units of the vibration gyroscope to outputs of the pulse signal generator during a first start-up time period, to outputs of the digital phase shifter during a second start-up time period, and to outputs of the variable gain amplifier during a measurement time period. Furthermore, a vibration gyroscope device and a method of driving a vibration gyroscope are described.
