I understand the concept of the Class D amp and this circuit, but in this particular case there is one part I just don't get.
What I don't understand is how the low side of the signal should work at the power stage. In case of the high side as I understand when the MOSFET is on, the current can flow from VCC to the load. But at the low side I don't understand how could current flow through the load and the low side MOSFET.
Could you please clarify it? Thanks!
