  • Receiver circuit with interference detection
    Patent number: 11469785
    Abstract: A receiver circuit includes an ADC, a processing channel, and an interference detection path. The processing channel is configured to process data samples provided by the ADC, and includes a notch filter. The interference detection path is configured to detect interference in the data samples, and includes a slicer, a slicer error circuit, and an interference detection circuit. The slicer is configured to slice input of the notch filter. The slicer error circuit is configured to compute an error of the slicer. The interference detection circuit configured to detect an interference signal in the error of the slicer, and set the notch filter to attenuate the interference signal.
