Abstract

PURPOSE: To accommodate a circuit configuration to integrated circuit from decreasing number of necessary parts by using a compensating filter circuit for which a low-pass compensation characteristic, a high-pass secondary attenuation characteristic and a medium-pass gain setting are realized by a single amplifier.
CONSTITUTION: In a compensating filter circuit 9 which removes a ripple of an output signal of a speed detection circuit 3 and increases a low frequency component including direct current to output to a motor driving circuit 6, a resistance R1 is connected from an input terminal a to b, a capacitor C1 is connected between the point b and an AC earth point, and a resistance R2 is connected between the point b and an inversion input terminal c of an amplifier 10. Further a constitution is such that a capacitor C2 is connected between the inversion input terminal c of the amplifier 10 and a point d, a resistance R3 is connected between the points b and d, and a capacitor C3 is connected between the point b and an output terminal e of the amplifier 10. Then, a setting is made so that ωL<ωH/2, where 1/(C1.C2.R2.R3)1/2= ωH, 1/C3.R3=ωL.
