  • Publication number: 20240146320
    Abstract: Described herein is a mismatch shaping technique applied in digital-to-analog converters (DACs) for high pass filtering mismatch related errors. The mismatch shaping scheme is based on a zero mean error encoding technique, which can be applied directly to binary coded signals, without the use for binary to thermometer decoding and element shuffling. In at least one example, an apparatus is provided which comprises a mismatch shaping circuitry to receive an N-bit binary input bits and to generate an (N+1)-bit digital output. In at least one example, the apparatus further comprises a digital-to-analog converter to receive the (N+1)-bit digital output and to generate an analog output, wherein the mismatch shaping circuitry is to encode the (N+1)-bit digital output to shape mismatch errors in the digital-to-analog converter.

  • Patent number: 11943003
    Abstract: A scheme for identifying wireless devices by capturing out-of-band information in addition to in-band information from wireless devices for enabling accurate classification of wireless devices. Both the in-band and out-of-band spectrum emissions of the received signal are used to capture hardware signatures and features. These hardware signatures are used to discriminate different wireless devices uniquely and efficiently, even when the devices have the same hardware with significantly reduced distortions. The out-of-band information can be extracted using radios with software defined capabilities. Deep learning-based device classification technique is applied that uses IQ samples collected from the RF signals to efficiently identify and classify high-performing transmitters that have the same, minimally distorted hardware components.
