Classification: CPC H  B  G | IPC B  G  H

Claim 8:
9. An electronic system, comprising:
a package including a base substrate and a cap coupled to the base substrate and defining therewith a chamber in the package;
a semiconductor die coupled to the base substrate in the chamber and including a semiconductor body; and
an array of micromachined ultrasonic transducers (MUTs) integrated at least in part in the semiconductor body, each MUT including a cavity in the semiconductor body, a membrane suspended over the cavity, and an actuator operatively coupled to the membrane and operable for generating a deflection of the membrane, wherein said membrane is configured to have a resonance frequency that matches an acoustic resonance frequency that, during operation of the MUT, develops in said chamber of the package.
