ABSTRACT:
A vibration gyroscope having stable sensitivity characteristic against temperature change has an amplifier circuit which amplifies a detection signal derived from a piezoelectric vibrator. The amplifier circuit includes an input terminal, an operational amplifier having a non-inversion input connected to the input terminal and an inversion input which is grounded, an output terminal connected to the output of the operation amplifier, a first temperature-sensitive element connected between the non-inversion input of the operation amplifier and the ground, and a second temperature-sensitive element connected between the inversion input of the operational amplifier and the output of the same.
