Abstract: An apparatus includes an integrated circuit configured to be operatively coupled to a sensor array that is configured to generate an ultrasonic wave. The integrated circuit includes a transmitter circuit configured to provide a first signal to the sensor array. The integrated circuit further includes a receiver circuit configured to receive a second signal from the sensor array in response to providing the first signal. The sensor array includes an ultrasonic transmitter configured to generate the ultrasonic wave in response to the first signal and a piezoelectric receiver layer configured to detect a reflection of the ultrasonic wave.

Abstract: A method of operation of an ultrasonic sensor array includes receiving a receiver bias voltage at a receiver bias electrode of the ultrasonic sensor array to bias piezoelectric sensor elements of the ultrasonic sensor array. The method further includes receiving a transmitter control signal at the ultrasonic sensor array to cause an ultrasonic transmitter of the ultrasonic sensor array to generate an ultrasonic wave. The method further includes generating data samples based on a reflection of the ultrasonic wave. The receiver bias voltage and the transmitter control signal are received from an integrated circuit that is coupled to the ultrasonic sensor array.
