Abstract

PURPOSE:To enable the removal of in-phase components with a simple circuit structure dispensing with a differential amplification circuit by virtually grounding one of output terminals of a Hall element while the output voltage thereof is drawn from the other. CONSTITUTION:A first control current terminal 11a of a Hall terminal 11 is connected to a constant currnet source 12 and a second control terminal 11b to the output terminal of an arithmetic amplifier OP11. The non-inversion input terminal of the arithmetic amplifier OP11 is grounded and a first output terminal 11 of the Hall element 11 is connected thereto. The Hall output voltage from the second output terminal 11d of the Hall element 11 is led to a meter 14 by way of the arithmetic amplifier OP12 and a non-inversion amplification circuit 13. The current running from the Hall element 11 flows to the Hall element 11 as control current and then, drawn into the arithmetic amplifier OP11. As the first output terminal 11c of the Hall element 11 is at an earth potential, the Hall output voltage removed in the in-phase alone can be obtained from the second output terminal 11d and taken out of the non-inversion amplification circuit 13.
