To provide a vibration angular velocity sensor capable of reducing the dispersion in the same-phase noise appearing in an angular velocity detection waveform of each sensor, and a same-phase noise level remaining in a differential waveform, independent of factors therein, so as to enhance the angular velocity detection precision, in an angular velocity sensor structure for outputting the differential waveform between two vibration sensor units, and a magnetic sensor regulation method wherein the edge phase of a detected waveform is hardly dispersed.
A differential amplification circuit 22 for computing the differential waveform between the first angular velocity detection waveform J1 and the second angular velocity detection waveform J2 is provided to off-set the same phase components acting on oscillators 4a, 4b of the first and second sensor units 100, 200 in an angular velocity detection direction y. Input gain regulating circuits 31, 32 are provided to regulate at least one out of an input gain of the first angular velocity detection waveform J1 and an input of the second angular velocity detection waveform J2 input into the amplification circuit 22, in order to reduce the remaining of the same phase components in the obtained differential waveform.
