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.

Radio frequency receiver

An electronic circuit comprises capacitive structures that are connected to one or a plurality of nodes, where each of the capacitive structures is formed by a capacitor or by a plurality of capacitors electrically connected in parallel. The electronic circuit further comprises additional capacitors that are each connected to the one or plurality of nodes. For at least one distance between capacitors, the capacitive structures have a same average of values defined, for each capacitor of each capacitive structure, by the number of capacitors of the circuit connected to the one or plurality of nodes and located at the distance from the capacitor of the capacitive structure.
