Abstract
PURPOSE: To increase reactivity against the voltage that changes in proportion to the change of input current by providing a current-magnetism converting element which takes out the current from a circuit connected by means of a bridge to the plural number of thin film elements sensitive to magnetism that presents the effect of anisotropic magnetic reluctance.
CONSTITUTION: If an input current I flows into a conductor layer 13, the magnetic field applied to the thin film element sensitive to magnetism 4 is proportioned to the change of the strength of the current, and the value of its resistance varies with the change of the current I. Therefore, the change of the value of the resistance is shown as the potential difference between connections 10 and 11 in the bridge circuit; and taken out by a detection circuit 17 composed of a differential amplifier. Thus it is possible to take out the voltage signal Vout in proprotion to the change of the input current I as an input signal from between output terminals 18 and 19. Consequently, while maintaining the electrical insulation of mutual elements between the electrically insulated conductor or semeconductor layer 13 and the thin film element sensitive to magnetism 4, the transmission of electric signals can be carried out unilaterally.
