Abstract
In the bias circuit of a magneto-resistive element signal amplifying circuit, a favorable high frequency characteristic is obtained by suppressing the influence of a parasitic capacitance that is generated. Furthermore, noise is removed by a lowpass filter including a resistor and a capacitor having a relatively small size in an integrated circuit.
