  • Patent number: 11444044
    Abstract: A power transistor die includes a semiconductor die with input and output die sides, and a transistor integrally formed in the semiconductor die between the input die side and the output die side, where the transistor has an input and an output (e.g., a gate and a drain, respectively). The power transistor die also includes an input bondpad and a first output bondpad integrally formed in the semiconductor die between the input die side and the transistor. The input bondpad is electrically connected to the input of the transistor. A conductive structure directly electrically connects the output of the transistor to the first output bondpad. A second output bondpad, which also may be directly electrically connected to the transistor output, may be integrally formed in the semiconductor die between the transistor and the output die side.

  • Publication number: 20220283283
    Abstract: A mechanism is provided for determining an unambiguous direction of arrival (DoA) for radio frequency (RF) signals received by a sparse array. A DoA angle domain is split into hypothesis regions. The hypothesis regions are derived from the phase differences of the antenna element pairs used for the DoA angle estimate. In each hypothesis region, the ambiguous phase of antenna element pairs is unwrapped according to expected wrap-around. After unwrapping the phase, for each hypothesis region, a phasor is calculated by combining the individual antenna element pair phasors. The hypothesis region that obtains the phasor with a largest amplitude is selected as the most likely DoA region and the phase of the winning phasor is used as an unambiguous estimate for the DoA angle.

  • Publication number: 20220283286
    Abstract: A method and system are provided to resolve Doppler ambiguity and multiple-input, multiple-output array phase compensation issues present in Time Division Multiplexing MIMO radars by estimating an unambiguous radial velocity measurement. Embodiments apply a disambiguation algorithm that dealiases the Doppler spectrum to resolve the Doppler ambiguity of a range-Doppler detection. Phase compensation is then applied for corrected reconstruction of the MIMO array measurements. The dealiasing processing first forms multiple hypotheses associated with the phase corrections for the radar transmitters based on a measured radial velocity of a range-Doppler cell being processed. A correct hypothesis, from the multiple hypotheses, is selected based on a least-spurious spectrum criterion. Using this approach, embodiments require only single-frame processing and can be applied to two or more transmitters in a TDM MIMO radar system.

  • Publication number: 20220278673
    Abstract: Duty cycles of pulse width modulation (“PWM”) pulses are determined by measurements taken with respect to an internally generated clock signal. One of these measurements calculates, in a continuous dynamic manner, a ratio of the number of cycles of the internally generated clock signal to one or more cycles of a PWM clock signal utilized as a time base for generation of the PWM pulses. This clock ratio measurement designates how many cycles of the internally generated clock signal will be used to designate a first portion of a duty cycle for each PWM pulse. Another measurement is utilized to determine a fractional portion of a cycle of the internally generated clock signal that will be used to designate a second portion of the duty cycle for each PWM pulse.

  • Patent number: 11432238
    Abstract: Exemplary aspects are directed to transceivers interlinked in a communication system, for example, in respective circuit-based nodes installed in battery-operated vehicle or other apparatus. Representative of the communication system are a first transceiver and a second transceiver which communicate with one another over a communication link, with the first transceiver initiating a request over the link to the second transceiver. The second transceiver may receive the request and, for a period of time in response to receiving to the request, monitor the link to detect whether any further signaling on the link by the first transceiver indicates to accept the request. In certain other more specific examples, the above aspects are used as part of a handshake protocol to mitigate delays and related issues in coordinating timely actions associated with the request.

  • Patent number: 11431389
    Abstract: A beamformer generates a null data packet (NDP) that includes various long training fields (LTFs). The beamformer generates the NDP based on a spatial mapping matrix that is a product of two matrices. One matrix has a number of rows equal to a number of antennas of the beamformer, and a number of columns equal to a number of LTFs in the NDP. Further, the other matrix has a number of rows and a number of columns equal to the number of LTFs in the NDP. The number of LTFs in the NDP is greater than a number of antennas of the beamformer. Further, the beamformer transmits the NDP to a beamformee to obtain channel state information associated with a channel between the beamformer and the beamformee, and enable beamforming therebetween.

When the plurality of flows are associated with multiple channels, a flow associated with each channel is selected based on the flow priority levels. Further, a channel is selected based on channel priority levels of channels that are currently arbitrating for the access. Based on the selected channel, flow data associated with one of the selected flows is outputted for granting the access to the shared resource.
