Abstract
A magnetoresistive-based signal shaping circuit for audio applications includes: a field emitting device configured for receiving an input current signal from an audio signal source and for generating a magnetic field in accordance with the input current signal, and a first magnetoresistive element having a first electrical resistance and electrically connected in series to a second magnetoresistive element having a second electrical resistance. The magnetoresistive-based signal shaping device provides an output signal across the second magnetoresistive element when an input voltage is applied across the first and second magnetoresistive element in series. The output signal is a function of the electrical resistance and yields a dynamic range compression effect. The first and second electrical resistance vary with the magnetic field in an opposite fashion.
