Abstract: In some examples, a pulser circuit is configured to provide a pulse signal in a first operational state, pre-charge components of the pulser circuit via a first signal path in a second operational state following the first operational state, wherein the first signal path includes first components having a first voltage tolerance and second components having a second voltage tolerance, the first voltage tolerance being less than the second voltage tolerance, and discharge a voltage of the pulser circuit to ground in a third operational state between the first operational state and the second operational state, and following the second operational state.

Abstract: A semiconductor device includes a trim storage and an encoder. The trim storage stores trim values. The encoder determines a magnitude of a supply voltage, determines a magnitude of a handle voltage, determines a source-to-handle voltage of a first transistor, and determines a source-to-handle voltage of a second transistor. Further, the encoder determines a target number of selectable first transistor units comprising the first transistor to select for the first transistor. Based on a trim value from the trim storage, the source-to-handle voltage of the first transistor and the source-to-handle voltage of the second transistor, the encoder determines a target number of selectable second transistor units comprising the second transistor to select for the second transistor. The encoder asserts control signals to select the target number of selectable first transistor units and the target number of selectable second transistor units.

Abstract: A passive beamformer for ultrasound imaging. An ultrasound probe includes a plurality of ultrasound transducers and beamforming circuitry. Each of the ultrasound transducers is configured to convert ultrasonic signal into electrical signal. The beamforming circuitry is coupled to the plurality of ultrasound transducers. The beamforming circuitry includes a plurality of passive delay circuits and a passive hold circuit. One of the passive delay circuits is coupled to each of the ultrasound transducers. The passive hold circuit is coupled to the passive delay circuits to store a sum of the charges received from the delay circuits.
