Abstract:
1. A magnetic sensor comprising: a pulse generator that receives an intermittent power supply signal from an external intermittent power supply and generates a pulse based on a rising edge of a power supply pulse for an ON state of the intermittent power supply signal, the pulse having a pulse width shorter than a power-on time of the intermittent power supply signal; a magneto-electric conversion element; a switch that controls, based on the pulse, a signal application time of the intermittent power supply signal to the magneto-electric conversion element within the power-on time; and an output waveform recovery circuit that changes the waveform of an output from the magneto-electric conversion element so that the pulse width of the output becomes equal to the power-on time of the external intermittent power supply, the output having a pulse width shorter than the power-on time of the intermittent power supply signal.
