  • Novel method of exciting a piezoelectric crystal
    Publication number: 20050275308
    Abstract: The invention describes the use of an electrical pulse that is a single square wave to excite a piezoelectric crystal. This pulse is applied alternately to either side of the crystal at twice the nominal resonant frequency of the crystal. This method provides a significant increase in net drive power to the crystal without the need to provide a sine wave excitation of plus and minus voltage to the crystal.
