Title: Signal processing circuit for magneto-resistance effect element
Inventor: SAWAKI MANABU
IPC: H03K17/80
Filed: 1984-02-02
Abstract: PURPOSE:To improve both S/N and stability by detecting the noise superposed on a magneto-resistance element with division of resistance and applying the detected noise to the non-reversed input of an error amplifier. CONSTITUTION:An output terminal 4 of a magneto-resistance element 2 is connected to an inverted input terminal of an error amplifier 8. While the both-end voltage of the element 2 is divided by dividing resistances 27 and 28, and the voltage at the dividing points are supplied to an amplifier 31. The noise component superposing on the element 2 is detected out of the output of the amplifier 31. Then a signal having the same phase and same level as the noise component superposed on the element 2 is produced based on the output of the amplifier 31 and applied to the non-inverted input terminal of the amplifier 8. Thus the noise superposed on the element 2 is eliminated. In this way, both S/N and stability of a signal processing circuit for magneto-resistance effect element are improved.
