Hello here I’ve a gate driver circuit output is square wave, but I want to used sine wave in my device....how to convert it?
Here is my circuit
61777B7B-2CB5-46C3-B971-C501F51B6521.jpegAnd then output is like this9773052B-6095-49E9-8C50-B1B27E745DFC.jpeg
I’m using RC filter but output will be strange....does I need removed inductor?

Please help me....thank you

Why not just use an audio amplifier and drive it with a sine wave?
But really, to get help, a lot more detail is needed.
What voltage and power out are you needing?
What is the frequency and does it vary?
What is the load device?
Anything else that may help form an answer.

Output frequency need 22KHz and voltage is 16V
Load device is a piezo element

Since the piezo element has its own resonant frequency, you may find it matters little whether you drive it with a square wave or a sine wave.
