Input/output devices are the interface between the controller and the controlled system. Input devices convert physical quantities to electrical signals, while output devices allow the controller to ...

As audio integrated circuit designs move to finer geometries, it becomes more difficult to design, and less cost-effective to integrate, high-performance analog circuits on the same piece of silicon ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...
