  • Amplifying stage working point determination
    Patent number: 9948245
    Abstract: An amplifier circuit including an amplifying stage and a predistortion stage is disclosed. The amplifier circuit outputs an output signal Xo. The predistortion stage is arranged for providing a predistortion signal Xp to be added to an input signal Xin of the amplifier circuit in order to compensate for non-linearites of said amplifying stage. According to the present invention, the amplifier circuit includes a working point unit arranged for determining a suitable working point WPsuitable to be used for said amplifying stage based on said predistortion signal Xp, and for adjusting an actual working point WPactual being used by said amplifying stage towards said suitable working point WPsuitable.
