ABSTRACT:
This amplifier is intended for amplifying variable signals superimposed on a continuous signal. This continuous signal serves in particular for biasing a component, a magnetoresistive resistor used as a hard disk reading head. To avoid the harmful effects of a sudden fluctuation in the continuous signal, this amplifier comprises a set of switchable reactive elements (70) for acting on said transfer function and a bias drift compensation circuit (80) for controlling the switching of said switchable elements with a view to anticipating the effects of said fluctuation.
