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.

Abstract: Symmetrical eight-shaped balun (BALanced-to-UNbalanced converter) comprising a first and second eye, each eye comprising conducting tracks forming turns. The eyes comprise an equal number of primary turns that form a first conducting path from a first terminal to a second terminal, in which in operation electrical current flows in a first direction in a first eye and in a second direction in a second eye. Moreover, the eyes further comprise an equal number of secondary turns that form a second conducting path from a third terminal to a fourth terminal, in which in operation electrical current flows in a first direction in a first eye and in a second direction in a second eye. The geometrical and electrical middle points of primary and secondary turns are all superposed and further are located in the same plane.
