Abstract
Disclosed is the audio amplifier comprising an input for an audio signal to be amplified and an output for powering a load on the basis of the amplified audio signal; a generator of reference voltage of very high linearity and low output impedance, able to receive, as input, the audio signal to be amplified; a power current generator comprising a power voltage generator whose output is connected to the output of the reference voltage generator through a coupling impedance. The coupling impedance comprises two coupling inductances mounted in series between the output of the reference generator and the output of the power voltage generator and an attenuation impedance linking a mid-point between the two coupling inductances and a reference potential, wherein the attenuation impedance includes an attenuation inductance.
