Hello everyone
I`ve been searching about class D amplifies.
What I know so far is that a class d amplifier is a switching amplifier.
There are three steps in creating a classe d amplifier.
1 - create PWM from signal.
2 - amplify output from PWM with switching transistors
3 - use a low pass filter.
The problem is that in step two, I have 2 transistors from Vcc to ground.
It seems that I need a delay circuit to prevent my circuit from having a short circuit from Vcc to ground(when both transistors would be conducting at the same time).
But i can't find a circuit like that to help me
Can anyone help me please?
This is the block diagram
