Abstract (en)

[origin: WO2018036974A1] The present invention relates to an amplifying device (10) for amplifying an input signal, comprising: - a first amplification stage (12), - a second amplification stage (14), each amplification stage (12, 14) comprising: · a switching circuit (22), the switching circuit (22) being capable of generating, as output (22A, 22B), a switched signal having at least two states, and · an inductive element (24) capable of smoothing the switched signal in order to obtain a smoothed signal (I1, I3), the smoothed signal (I1, I3) having a useful component and a parasitic component. The amplifying device (10) further comprises a compensation circuit (16), for each amplification stage (12, 14), capable of generating a compensation signal (I2, I4) for compensating the parasitic component of the smoothed signal (I1, I3) generated in the inductive element (24) of said amplification stage (12, 14).
