Abstract
An electronic device, includes sigma-delta modulation circuit to operate with a clock signal and having output circuitry to deliver a digital data signal. First circuitry delivers a radiofrequency transposition signal. A notch filter includes radiofrequency digital-to-analog conversion blocks, having first input circuitry coupled to the output circuitry. Second input circuitry receives the radiofrequency transposition signal. Second output circuitry delivers a radiofrequency analog signal. Digital delay circuitry is controlled by the clock signal and includes a delay block between the two first input circuits. The frequency of a notch of the notch filter is related to the value of the delay from the delay block. Summation circuitry sums the radiofrequency signals.
