Abstract: An electronic device applies a frequency offset function to a first signal having a first frequency. The device includes a delay element configured to output a second signal corresponding to the first signal delayed by a duration equal to a first period of said signal divided by four. A circuit branch includes a first circuit configured to divide the frequency of the first signal by a given number coupled in series with a second circuit configured to implement an integration. The circuit branch outputs a third signal and a fourth signal. A single side band mixing circuit processes the first signal, second signal, third signal and fourth signal to generate an output signal.
