    Abstract: A wobulated signal generator includes a chain of delay elements and control circuitry. The chain of delay elements includes first delay elements, second delay elements, and third delay elements. The control circuitry, in operation, enables a number of the first delay elements, disables a number of the third delay elements, and enables a selected number of the second delay elements, defining a period of time between two consecutive rising edges of a digital wobulated signal at an output of the wobulated signal generator. The control circuitry monitors an average frequency of the digitally wobulated signal, and selectively modifies the number of enabled first delay elements and the number of disabled third delay elements based on the monitored average frequency of the digitally wobulated signal.

    Abstract: In an embodiment, a radio frequency (RF) receiver circuit includes a main circuit and a wake-up circuit. The main circuit is configured to process RF signals. The wake-up circuit is configured to detect a reception of the RF signals. The wake-up circuit includes an automatic gain control (AGC) loop, and is configured to have a first operating mode where a set point voltage of the loop has a first substantially constant value, and a second operating mode where the set point voltage of the loop has a second value dependent on a power supply voltage of the wake-up circuit.
