ABSTRACT:
An angular velocity detector circuit composed of: an oscillator circuit including an inverting amplifier connected between a driving electrode of a quartz crystal and an electrode for detecting an electric field generated in the quartz crystal by a Corioli's force when the quartz crystal is rotated; a differential amplifier circuit connected at its input terminals to the detecting electrode of the quartz crystal; a detector circuit which receives the output from the differential amplifier circuit and using the output from the oscillator circuit as detection signals; and an output amplifier circuit which receives the output from the detector circuit.
