Abstract
A signal processing arrangement comprises an amplifier (AMP V) that includes a stage with complementary transistors (MP, MN) of opposite conductivity type arranged in series between two supply lines (+, −). A controllable biasing circuit (CCS) is provided for changing a quiescent operating point of the stage as a function of a control signal (CS). A control arrangement measures an even order 5 distortion of the amplifier (AMP V) and adjusts the control signal (CS) so that the even order distortion is below a critical level.
