Abstract
A first differential amplifier circuit is provided having a first and second input terminal suited for connection to a magnetic head. The first differential amplifier circuit includes first and second output terminals for providing a read output signal. A second differential amplifier circuit is provided which has first and second input terminals connected to the first and second input terminals, respectively, the first differential amplifier circuit. The second differential amplifier circuit also includes first and second output terminals. A first feedback capacitor is provided which is connected between the first input terminal of the first differential amplifier circuit and the first output terminal of the second differential amplifier circuit. A second feedback capacitor is provided which is connected between the second input terminal of the first differential amplifier circuit and the second output terminal of the second differential amplifier circuit.
