Then a prescribed reference voltage Vr including zero volt is impressed to a minus input of the operational amplifier 5. Since the amplification factor of the operational amplifier 5 is actually infinite, the relation of Vi=Vr is obtained. Then, from the relation of R(Y)=Vi/Ic, the resistance R(Y) of the 1st and 2nd variable resistive elements 30, 40 is controlled optionally by an output current Ic of a constant current means 27. Thus, even if the characteristic of the 1st and 2nd variable resistive elements 30, 40 in pairs very ununiform between different pairs, since the characteristic of both elements as a pair is substantially identical, both elements shows a resistance with respect to the current Ic.
