Abstract

A vibrating gyroscope includes a vibrator having a triangular prism shaped vibrating body and piezoelectric elements. An oscillation circuit is connected between two piezoelectric elements and another piezoelectric element. Output signals from two piezoelectric elements are applied to input terminals of a differential circuit. The differential circuit is connected to a synchronous detecting circuit, and the synchronous detecting circuit is connected to a smoothing circuit. A temperature compensating capacitor is connected between two piezoelectric elements that are connected to the differential circuit. The oscillation circuit consists of an amplifier and a phase shifter having a resistor and a capacitor. As the capacitor used in the phase shifter, the temperature compensating capacitor may be used.
