摘要： The present invention aims to provide an angular velocity detection device which is capable of reducing the effect of coupling between a drive electrode and a first displacement detection electrode by a floating capacity, and is low in cost. In the angular velocity detection device, an oscillating body 21 is displaceable in a first direction and a second direction which orthogonally intersect each other. The oscillating body 21 is oscillated in the first direction by an electrostatic force corresponding to a drive signal generated by a non-interference signal generator 1. A carrier signal generated by the non-interference signal generator 1 is applied to the oscillating body 21. A first displacement detection circuit 3 and a second displacement detection circuit 4 each detect a displacement of the oscillating body 21 as a displacement modulation signal indicative of a change in electrostatic capacity synchronized with the carrier signal to thereby detect an angular velocity. Here, the frequency of the drive signal and the frequency of the carrier signal are set so as to be generated at such a frequency ratio that a higher harmonic of the drive signal multiplied by an odd number does not the displacement modulation signal.

摘要： In a magnetic-field angle detection device and a rotation angle detection device in which the accuracy of the measured angle is not degraded even if the MR ratio of the tunneling magnetoresistance element is increased. In a magnetic-field-angle measurement apparatus including a magnetic-field-angle detection circuit and a magnetic sensor having a tunneling magnetoresistance element with a pinned magnetic layer, the magnetic-field-angle detection circuit has a power-supply unit that outputs a constant voltage as a bias voltage to the tunneling magnetoresistance element of the magnetic sensor and a current-detection unit that detects an output current of the tunneling magnetoresistance element. The accuracy of the measured angle of the magnetic-field angle detection device and the rotation angle detection device is improved by measuring the tunneling magnetoresistance element current while maintaining the terminal voltage of the tunneling magnetoresistance element constant with input impedance of the current-detection unit as zero.
