摘要： A linearity compensation circuit is disclosed for improving the linearity of a sensing signal. The linearity compensation circuit may include a compensator that is capable of receiving a sensing signal from a sensor and generating a compensation signal based on the sensing signal. The linearity compensation circuit may also include an output circuit that is capable of combining the compensation signal and the sensing signal to generate a compensated signal that exhibits an improved linearity. Also disclosed is a sensing apparatus which includes a sensor and the linearity compensation circuit. The sensing apparatus may thus be able to generate a sensing signal that is linear over a wider dynamic range.

摘要： The present invention relates to a coil and a manufacturing method thereof. The method includes: depositing a first metal layer on a first surface of a wafer and patterning the first metal layer to obtain a first patterned metal layer on the first surface; etching a plurality of through holes on a second surface of the wafer to the first surface of the wafer, and depositing a second metal layer on the second surface of the etched wafer and patterning the second metal layer to obtain a plurality of through hole metals and a second patterned metal layer on the second surface; and, dicing the wafer to obtain a plurality of independent coils. Each coil comprises the first patterned metal layer, the through hole metals and the second patterned metal layer. The first patterned metal layer is coupled with the second patterned metal layer through the through hole metals. Thus, high-precision coils can be efficiently manufactured in batches and at low costs through a wafer level process. The coil may be used for generating or inducing an electromagnetic field.

摘要： A method involves a first magnetic sensor of a magnetic apparatus measuring an external magnetic field. The method also involves a signal processing circuit of the apparatus performing calibration using a second sensor in response to the external magnetic field. The first sensor and the second sensor are formed on the same substrate. There will be at least one magnetic sensor is used to measure the external magnetic field, and the other magnetic sensor is used in calibration, and therefore, the method ensures an effective output signal can be generated during calibration and enhances the accuracy of the measurement.
