  • Method for acoustic power scalable charge-redistribution ultrasonic system with on-chip aberration compensation for portable ultrasonic applications
    Patent number: 11672504
    Abstract: The present disclosure is generally directed to a method for driving an ultrasonic transducer. The method includes coupling a driving electrode and a ground electrode of the ultrasonic transducer to a power supply and a ground, respectively, during a first time period based on a received drive signal. The method further includes decoupling the driving electrode and the ground electrode of the ultrasonic transducer from the power supply and the ground, respectively, to float the driving electrode and the ground electrode of the ultrasonic transducer during a second time period based on the received drive signal to store a charge between the driving electrode to the ground electrode.
    Type: Grant

  • Systems and method for acoustic power scalable charge-redistribution ultrasonic system with on-chip aberration compensation for portable ultrasonic applications
    Patent number: 11185304
    Abstract: The present disclosure is generally directed to an ultrasonic transducer interface system for use within portable 2-D ultrasonic imagers and includes an on-chip adaptive beamformer and Charge-Redistribution TX (CR-TX) to provide a drive strength of up to 500 pF/channel at 5 MHz (or 10 nF at 250 kHz) while reducing the TX drive power by at least 30% compared to other ultrasonic transducer TX drivers. The ultrasonic transducer interface system can be implemented in a single chip via, for example, a complementary metal oxide semiconductor (CMOS) process.
