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.
