    Hey guys,

    I need your help. I am a bit lost. I have to build an amplifier circuit for a piezoelectric disk for ultrasound generation in university.
    The technical data (piezoelectric disk):

    Resonant frequency = 80 kHz
    Electrical capacity = 35 nF
    Max. Supply voltage = 400 V

    In the university I have a function generator which supplies me with an alternating voltage with the desired frequency (70 kHz). I think it would make most sense to build a driver circuit.

    I would be very grateful if you could explain me how to proceed.
    How should the amplifier circuit look like, which components and what else I have to consider.


    Thanks in advance
