I have a strange problem with the MOSFET Push-Pull configuration of an output stage of a simple buck converter.
On the falling edge of the Low-Side MOSFET I get an effect like ringing, but it is actually following the rising edge of the other MOSFET. What can it be? Can it be caused by stray inductance and the current of the High-Side MOSFET induces some into the gate of the Low-Side MOSFET?
I will include three pictures. One with the circuit, one with the PCB (Some explanations under the picture) and the last one with the problem.
