Vibration gyroscope for navigation system

摘要

The vibration gyroscope (10) has an amplifier circuit (30), which amplifies a detection signal, which is derived from a piezoelectrical vibrator, or a signal, which is related to the detection signal. The amplifier circuit has an operation amplifier (33) and at least two temperature sensitive elements (35, 37). The amplifier circuit has an input connection (31), which is connected with the non-inverting input of the operation amplifier. So that the inverting input of the operation amplifier lies at earth. An output connection (39) is connected with the output of the operation amplifier. The at least 2 temperature sensitive elements include a first element connected between the inverting input of the operation amplifier and earth, and a second temperature sensitive element, which is connected between the inverting input of the operation amplifier and the operation amplifier output.
