    Abstract: Aspects of the technology described herein related to controlling, using control circuitry, modulation circuitry to modulate and delay first ultrasound data generated by first ultrasound transducers positioned at a first azimuthal position of an ultrasound transducer array of an ultrasound device and second ultrasound data generated by second ultrasound transducers positioned at a second azimuthal position of the ultrasound transducer array of the ultrasound device, such that the first ultrasound data is delayed by a first delay amount and the second ultrasound data is delayed by a second delay amount that is different from the first delay amount. The first and second ultrasound data received from the modulation circuitry may be filtered and summed. The ultrasound transducer array, the control circuitry, the modulation circuitry, the filtering circuitry, and the summing circuitry may be integrated onto a semiconductor chip or one or more semiconductor chips packaged together.

    Abstract: Aspects of the technology described herein relate to apparatuses and methods for performing elevational beamforming of ultrasound data. Elevational beamforming may be implemented by different types of control circuitry. Certain control circuitry may be configured to control memory such that ultrasound data from different elevational channels is summed with stored ultrasound data in the memory that was collected at different times. Certain control circuitry may be configured to control a decimator to decimate ultrasound data from different elevational channels with different phases. Certain control circuitry may be configured to control direct digital synthesis circuitry to add a different phase offset to complex signals generated by the DDS circuitry for multiplying with ultrasound data from different elevational channels.

    Abstract: Aspects of the technology described herein relate to control circuitry configured to turn on and off the ADC driver. In some embodiments, the control circuitry is configured to turn on and off the ADC driver in synchronization with sampling activity of an ADC, in particular based on when an ADC is sampling. The control circuitry may be configured to turn on the ADC driver during the hold phase of the ADC a time period before the track phase and to turn off the ADC driver during the hold phase a time period after the track phase. In some embodiments, the control circuitry is configured to control a duty cycle of the ADC driver turning on and off. In some embodiments, the control circuitry is configured to control a ratio between an off current and an on current in the ADC driver.

    Abstract: Aspects of the technology described herein related to an ultrasound processing unit (UPU) including gray-coding circuitry configured to convert standard binary-coded digital ultrasound signals to gray-coded digital ultrasound signals and gray-decoding circuitry coupled to the gray-coding circuitry and configured to convert the gray-coded digital ultrasound signals to standard binary-coded digital ultrasound signals. The UPU may include an analog portion, a digital portion, and a data bus configured to route the gray-coded digital ultrasound signals from the analog portion to the digital portion subsequent to converting the standard binary-coded digital ultrasound signals to the gray-coded digital ultrasound signals. The analog portion may include multiple analog front-ends (AFEs), the gray-coding circuitry, and an analog-to-digital converter. The digital portion may include the gray-decoding circuitry. A data bus from one AFE may pass over another AFE.

    Abstract: Aspects of the technology described herein relate to an ultrasound device including a first die that includes an ultrasonic transducer, a first application-specific integrated circuit (ASIC) that is bonded to the first die and includes a pulser, and a second ASIC in communication with the second ASIC that includes integrated digital receive circuitry. In some embodiments, the first ASIC may be bonded to the second ASIC and the second ASIC may include analog processing circuitry and an analog-to-digital converter. In such embodiments, the second ASIC may include a through-silicon via (TSV) facilitating communication between the first ASIC and the second ASIC. In some embodiments, SERDES circuitry facilitates communication between the first ASIC and the second ASIC and the first ASIC includes analog processing circuitry and an analog-to-digital converter. In some embodiments, the technology node of the first ASIC is different from the technology node of the second ASIC.
