| 摘要 |
The present invention relates to a method of linearization an amplifier ( 4 ) and also to amplifier circuitry. The method comprises the steps of generating a linearization signal ( 10 ) that substantially corresponds to low-frequency components of the square of an input signal ( 7 ) to the amplifier ( 4 ), processing the linearization signal, combining ( 15 ) the linearization signal with the input signal to form a modified input signal, and amplifying the modified input signal by means of the amplifier ( 4 ). |
