Abstract
An amplification device includes an amplification stage having a transconductance amplification transistor and an output terminal. A biasing circuit is configured to bias in common mode the output terminal to a bias potential obtained on the basis of a voltage present between the gate and the source of the amplification transistor, and to compensate for parasitic variations of the voltage present between the gate and the source of the amplification transistor.
