Angular rate sensor
An angular rate sensor is characterized by having electrodes constituting an exciting unit for providing a vibrator with vibration, an electrode constituting a means for detecting a vibration level of the vibrator, an electrode constituting a first detection means for detecting Coriolis' force generated responsive to an angular rate, a second detecting electrode for detecting a signal of reverse polarity to that of the first detecting electrode, a driving circuit for taking as an input a signal from the electrode for detecting the vibration level and outputting a signal to the electrodes, and a first detection circuit and a second detection circuit for taking respective inputs of detected signals from the first detecting electrode and the second detecting electrode.
