1. An ultrasound device comprising:
a semiconductor chip or a package of one or more semiconductor chips integrating each of the following:
an ultrasound transducer array having:
a first plurality of ultrasound transducers positioned at a first position of the ultrasound transducer array and configured to generate first ultrasound data; and
a second plurality of ultrasound transducers positioned at a second position of the ultrasound transducer array and configured to generate second ultrasound data;
modulation circuitry configured to modulate the first ultrasound data and the second ultrasound data such that the first ultrasound data is delayed by a first delay and the second ultrasound data is delayed by a second delay;
filtering circuitry configured to filter the first and second ultrasound data received from the modulation circuitry; and
summing circuitry configured to sum the first and second ultrasound data received from the filtering circuitry.
