摘要： There are arranged a sensor magnet fixed to a rotary shaft and configured to generate a magnetic field for detecting a rotation angle, and a plurality of sensors arranged so as to be opposed to the sensor magnet and each configured to output a sine signal and a cosine signal in accordance with the magnetic field. First and second sensors are arranged on two radial lines different from each other, respectively, out of three radial lines dividing a circumference about the rotary shaft of the sensor magnet into six equal parts. An angle calculation unit is configured to carry out calculation so that 3n-th (n is a natural number) order harmonic components out of odd-order harmonic components of each of the sine signal and the cosine signal output by the first and second sensors cancel one another, to thereby calculate the rotation angle.

摘要： A CV conversion amplifier is provided that can secure a sufficient capacitance-to-voltage conversion gain and a sufficient amplitude range of an output voltage with a small consumption current. A capacitive sensor using the CV conversion amplifier is provided with low electric power, low noise, and a wide tolerance of input signals. The CV conversion amplifier accepts outputs, as inputs, from a first capacitance and a second capacitance whose capacitance is changed depending on a physical quantity and converts a capacitance value into a voltage.

摘要： This application relates to circuitry for processing sense signals generated by MEMS capacitive transducers for compensating for distortion in such sense signals. The circuitry has a signal path between an input (204) for receiving the sense signal and an output (205) for outputting an output signal based on said sense signal. Compensation circuitry (206, 207) is configured to monitor the signal at a first point along the signal path and generate a correction signal (Scorr); and modify the signal at at least a second point along said signal path based on said correction signal. The correction signal is generated as a function of the value of the signal at the first point along the signal path so as to introduce compensation components into the output signal that compensate for distortion components in the sense signal. The first point in the signal path may be before or after the second point in the signal path. The monitoring may be performed in an analogue or a digital part of the signal path and in either case the modification may be applied in an analogue or a digital part of the signal path.
