Abstract
A class AB amplifier and its distortion corrector are provided for obtaining linear amplification, even for low input signal levels. For this, at low levels, the distortion corrector has a response Vs'=f(Ve') (with Ve' and Vs': input and output voltages of the corrector) whose representative curve has a concavity turned towards the increasing values of Vs' whereas, up to now, a prejudice born of an insufficiently precise study of class AB amplifiers led to an inverse curve for the response of the corrector.
