An amplifier circuit for a piezoelectric disk for ultrasound

[Isabella_]

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

What circuit did you come up with for a piezo driver?
