Driving the Piezoelectric transduce 113KHz
Posted: Wed May 26, 2021 4:02 pm
Hi,
I've 113KHz piezo transducer @113KHz,
I'm trying to drive using esp32 PWM.
The circuit is like below

I don't see any signal at the output to the transducer
Few more images
a) PWM from esp32

b)Drain output- https://drive.google.com/file/d/1zXeZok ... sp=sharing
c)Drain out without the supply- https://drive.google.com/file/d/1zNONu0 ... sp=sharing
