Abstract
The invention concerns a pre-distorting linearization circuit, comprising a splitter circuit with an input forming the input of the linearization circuit and first and second outputs feeding first and second parallel stages respectively, of which at least one has a defined distortion characteristic, and a combining circuit receiving the signals provided by the first and second stages at first and second inputs respectively and having a recombination output. According to the invention, the first and second stages have first and second transistors respectively having different dimensions, which confer different non-linearity characteristics thereon, such that for the same voltage on the input of the linearization circuit, the first stage exhibits a higher degree of non-linearity than the second stage.
