  • Patent number: 11669116
    Abstract: A low dropout regulator includes a proportional-to-absolute-temperature (PTAT) circuit, an amplification circuit, and an output circuit. The PTAT circuit outputs one current, and the amplification circuit outputs one or more currents. The one or more currents are outputted by the amplification circuit based on collector-emitter voltages associated with transistors of the PTAT circuit. Alternatively, the one or more currents are outputted by the amplification circuit based on the current outputted by the PTAT circuit and the collector-emitter voltages associated with the transistors of the PTAT circuit. The output circuit generates one or more output voltages based on at least one of a base-emitter voltage associated with a transistor of the PTAT circuit and a current of the one or more currents outputted by the amplification circuit.

  • Patent number: 11662425
    Abstract: A mechanism is provided by which a radar image can be generated using mmWave transmissions from 5G-NR type base station antenna arrays. Base stations in 5G-NR use a beam searching sequence utilizing a defined synchronization signal burst (SSB) during their communication initialization with client devices. Embodiments utilize these SSB signals as a radar “chirp” to build a radar image of the base station surrounding in parallel with the typical 5G-NR communication initialization. Antennas on the base station can receive the reflected signals to define the radar image, in conjunction with correlation and time-management logic to properly associate received reflected signals with original transmitted signals. Such information can be processed by a synthetic aperture radar processing logic to form the radar image.

  • Publication number: 20230160997
    Abstract: Described are method and systems that implement time frequency domain threshold interference and localization fusion to resolve interference issues in an automotive radar system, that produces spectrograms using Short-Time Fourier Transform (STFT) for all receiving antennas of the automotive radar system. For each STFT frequency a suppression threshold is determined. Interference is isolated for each STFT frequency by removing the interference from samples that are above the suppression threshold by using a filter. Direction of Arrival (DoA) is estimated for each interference spectrogram cell using measurements from all the receiving antennas. Interference samples are clustered using the DoA into epochs of chirps.
