Abstract
A method for minimizing harmonic distortion and/or intermodulation distortion of a radiofrequency signal propagating in a radiofrequency circuit formed on a semiconductor substrate coated with an electrically insulating layer, wherein a curve representing the distortion as a function of a power of the input or output signal exhibits a trough around a given power (PDip), the method comprises applying, between the radiofrequency circuit and the semiconductor substrate, an electrical potential difference (VGB) chosen so as to move the trough toward a given operating power of the radiofrequency circuit.
