Interesting stuff !Pretty pimp of O&amp;B and Dr. Nielsen to post those papers online.... I have not had a chance to read any of them in depth (would take a few hrs at least); but at first glance it seems that instead of using a carrier wave at a single frequency to switch the outputs these amps use a variable frequency and a unique feedback method to increase bandwidth and minimize high frequency switching noise...I don't quite understand how the carrier waves are generated yet; but its clear they don't use a clock generator as conventional class D amps do...</blockquote>
