    Abstract: The apparatus is a wake-up circuit including a first comparator coupled to an input signal and configured to compare the input signal to a first comparison value. The wake-up circuit includes a second comparator coupled to the input signal and configured to compare the input signal to a second comparison value. The wake-up circuit further includes an exclusive OR gate. A first input of the exclusive OR gate is coupled to an output of the first comparator. A second input of the exclusive OR gate is coupled to an output of the second comparator. The wake-up circuit also includes a tunable charge pump coupled to an output of the exclusive OR gate and configured to convert a signal from the exclusive OR gate to a DC value to wake up a circuit being monitored.

    Abstract: Certain aspects of the present disclosure provide methods and apparatus for autonomous receive (RX) detection. One example method for wireless communications generally includes powering down a portion of a receive path in a first module; detecting, in a second module comprising another portion of the receive path, that a radio frequency (RF) signal has been received by the second module while the portion of the receive path in the first module is powered down; and sending a control signal to power up the portion of the receive path in the first module, based on the detection.
