A few days ago i found a pdf depicting a self oscillating class d with BD modulation, something i have never before seen and dident even know wat possible.

I had to come up with the component values myself but this is the basic circuit.

And a link to the paper for those interested: Low cost implementation of filterless class D audio amplifier with constant switching frequency_°Ù¶ÈÎÄ¿â
