Angular velocity detection circuit


Title: Angular velocity detection circuit.
Abstract: An angular velocity detection apparatus includes a vibrator that generates a signal that includes an angular velocity component and a vibration leakage component, a driver section that generates the drive signal, and supplies the drive signal to the vibrator, an angular velocity signal generation section that extracts the angular velocity component from the signal generated by the vibrator, and generates an angular velocity signal corresponding to the magnitude of the angular velocity component, a vibration leakage signal generation section that extracts the vibration leakage component from the signal generated by the vibrator, and generates a vibration leakage signal corresponding to the magnitude of the vibration leakage component, and an adder-subtractor section that adds the vibration leakage signal to the angular velocity signal, or subtracts the vibration leakage signal from the angular velocity signal, in a given ratio to correct temperature characteristics of the angular velocity signal. ...
