ABSTRACT:
A circuit for producing a signal whose magnitude is a chosen amplitude compensation characteristic of the signals produced by a magnetoresistive (MR) element comprising an input stage which produces an amplified output signal which is coupled to the output stage, and control signals proportional to the resistance of the MR element and inversely proportional to the resistance of the MR element which are coupled to a feedforward circuit. The feedforward circuit generates a chosen amplitude equalization characteristic of the signals coupled to the feedforward circuit, and this signal is coupled to a bias terminal of the output stage so that the output stage produces a signal representing the chosen amplitude compensation characteristic of the signals produced by the MR element.
