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.
