Provided is an apparatus including: a first input circuit which inputs signal from a first communication line; a second input circuit which inputs a signal from a second communication line; a reference voltage generation circuit which generates a reference voltage; and a comparison circuit which compares the reference voltage with a voltage of the first communication line. The first input circuit and the second input circuit adjust judgement thresholds to be used for judging a signal value according to the comparison result obtained by the comparison circuit.

Apparatus for inputting signal from communication line and method thereof

An object is to provide a magnetic sensor module that suppresses a size of a magnetic sensor chip while applying a uniform calibration magnetic field to a magneto-resistive element. Provided is a magnetic sensor module comprising an IC chip having a first coil; and a magnetic sensor chip that is disposed on a surface of the IC chip and includes a first magnetic sensor that detects magnetism in a direction of first axis, wherein a planar shape of the IC chip encompasses a planar shape of the magnetic sensor chip, and the first coil has a planar shape including three or more sides, and is, when seen in a cross section along at least one side of the planar shape, is formed so as to cover a region, in a direction of the one side, of the first magnetic sensor.

Magnetic sensor module and IC chip employed in same

A magnetic sensor device includes a composite chip component, and a sensor chip mounted on the composite chip component. The sensor chip includes a first magnetic sensor, a second magnetic sensor, and a third magnetic sensor that detect components of an external magnetic field that are in directions parallel to an X direction, parallel to a Y direction, and parallel to a Z direction, respectively. The composite chip component includes a first magnetic field generator, a second magnetic field generator, and a third magnetic field generator for generating additional magnetic field components that are in directions parallel to the X direction, parallel to the Y direction, and parallel to the Z direction, respectively.

Magnetic sensor device

A magnetic sensor device includes three magnetic sensors for detecting components of an external magnetic field that are in three directions, a magnetic field generation section, and a correction processor. The magnetic field generation section generates additional magnetic field components in three directions used for measurements of main- and cross-axis sensitivities of the three magnetic sensors. The correction processor corrects respective detection signals of the three magnetic sensors on the basis of the measurement results of the main- and cross-axis sensitivities of the magnetic sensors.
