Abstract

A circuit device adapted to perform detection of angular velocity observed by a capacitance type angular velocity transducer includes a drive device, a detection device, a vibration frequency controller adapted to variably control at least one of a detection frequency and a drive frequency of the capacitance type angular velocity transducer, and a storage adapted to store a correction parameter group adapted to correct a sensor characteristic of the capacitance type angular velocity transducer due to a variation of at least one of the detection frequency and the drive frequency.
