Angular velocity sensor and angular velocity sensor control method

An angular velocity sensor comprising:

• an angular velocity sensor element having:
• a monitor electrode;
• a drive electrode;
• a sense electrode;
• and
• a weight;
• and
• a circuit electrically connected to the monitor electrode, the drive electrode, and the sense electrode,
• wherein the circuit has:
• a first CV converter connected to the monitor electrode;
• a second CV converter connected to the sense electrode;
• a comparator that a signal from the first CV converter and a signal from the second CV converter are input to;
• and
• an output circuit that a signal from the comparator is input to and that outputs a signal to the first CV converter or the second CV converter.

A method for controlling an angular velocity sensor including an angular velocity sensor element, the angular velocity sensor element including a monitor electrode, a drive electrode, a sense electrode, and a weight, the method comprising:

• a first step of CV converting a signal from the monitor electrode;
• a second step of CV converting a signal from the sense electrode;
• a third step of comparing the signal having been CV converted in the first step with the signal having been CV converted in the second step;
• and
• a fourth step of changing a signal to be supplied to the monitor electrode or the sense electrode, based on a result of the comparison obtained in the third step.
