A converter is for a differential input signal into a single-ended output signal and may include a differential pair of identical first and second transistors driven by the differential input signal, and a circuit for filtering DC components, connected between the current terminal of the second transistor not in common with the first transistor of the differential pair and an output node of the converter on which the single-ended output signal is generated. The converter generates a single-ended signal without employing a transformer, in lieu thereof the converter may include a current generator biasing the differential pair by of third and fourth output transistors, in a current mirror configuration, connected in series with the first and second transistors, respectively. The converter may also include degeneration resistors of the transistors of the current mirror, dimensioned such that the gains of the converter for each of the two input nodes of the differential signal are equal and of opposite sign.
