Abstract: Described herein is a transceiver circuit for a capacitive micromachined ultrasonic transducer (CMUT), provided with: a transmitter stage, which generates excitation pulses for a first node of the CMUT transducer during a transmitting phase, a second node of the CMUT transducer being coupled to a biasing voltage; a receiver stage that is selectively coupled to the first node during a receiving phase and has an amplification stage; a switching stage that couples the receiver stage to the first node during the receiving phase and decouples the receiver stage from the first node during the transmitting phase. The amplification stage is provided with a charge amplifier that has an input terminal and is biased as a function of a biasing voltage; and the switching stage is coupled to the same biasing voltage thereby minimizing an injection of charge into the input terminal upon switching from the transmitting phase to the receiving phase.

Abstract: A signal generator generates an electrical signal that is sent to an amplifier, which increases the power of the signal using power from a power source. The amplified signal is fed to a sender transducer to generate ultrasonic waves that can be focused and sent to a receiver. The receiver transducer converts the ultrasonic waves back into electrical energy and stores it in an energy storage device, such as a battery, or uses the electrical energy to power a device. In this way, a device can be remotely charged or powered without having to be tethered to an electrical outlet.
