Abstract
A current sensor includes a magnetic sensor, a magnetic sensor, a first calculator, a second calculator, and an output. The first magnetic sensor senses a magnetic field to generate a first sensor signal and a second sensor signal. The second magnetic sensor senses a magnetic field having a phase opposite to that of the magnetic field sensed by the first magnetic sensor in accordance with the current to generate a third sensor signal and a fourth sensor signal. The first calculator receives the first sensor signal and the third sensor signal to generate a first arithmetic signal. The second calculator receives the second sensor signal and the fourth sensor signal to generate a second arithmetic signal. The output receives the first arithmetic signal and the second arithmetic signal and generates an output signal based on the respective signals that are input.
