Abstract
Aspects of the technology described herein relate to ultrasound circuits that employ a differential ultrasonic transducer element, such as a differential micromachined ultrasonic transducer (MUT) element. The differential ultrasonic transducer element may be coupled to an integrated circuit that is configured to operate the differential ultrasonic transducer element in one or more modes of operation, such as a differential receive mode, a differential transmit mode, a single-ended receive mode, and a single-ended transmit mode.
Claims20
An ultrasound device, comprising:
- a differential capacitive micromachined ultrasonic transducer (CMUT) element operable in each of a plurality of modes including:
- a differential receive mode,
- a differential transmit mode,
- a single-ended receive mode, and
- a single-ended transmit mode;
- and
- an integrated circuit, coupled to the differential CMUT element, that:
- selects a mode from the plurality of modes;
- and
- operates the differential CMUT element in the selected mode.
An ultrasound device, comprising:
- a differential micromachined ultrasonic transducer (MUT) element;
- and
- an integrated circuit coupled to the differential MUT element and configured to operate the differential MUT element in at least one of a differential receive mode and a differential transmit mode and at least one of a single-ended receive mode and a single-ended transmit mode.
