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.

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: In one example, an apparatus for multimode radar comprises: a transmit circuit; a receive circuit; and a controller configured to: transmit a first signal using the transmit circuit; set a maximum input signal level at the receive circuit, wherein the maximum input signal level is set based on a minimum of the first distance range; and detect, using the receive circuit, the reflected first signal; transmit a second signal using the transmit circuit; set a minimum input signal level at the receive circuit, wherein the minimum input signal level is set based on a maximum of the second distance range; detect, using the receive circuit, the reflected second signal; and measure a distance from an object based on one of the reflected first signal or the reflected second signal.
