摘要

An angular velocity sensor includes a sensor device and an amplification circuit. The sensor device generates a detection signal corresponding to an angular velocity. The amplification circuit generates both a first output signal by non-inverting amplifying the detection signal with a first gain and a second output signal by inverting-amplifying the detection signal with the first gain, and outputs the first output signal and the second output signal in order to obtain an angular velocity signal by calculating a difference between the first output signal and the second output signal.
