Subject: LF: CLASS D/E

Hi All

Where would I find a good book about class D and E amp design including the mathematics? and matching transformer info using ferrite materials for optimum efficiency at RF into 50ohm loads.

I have found some info on the subject but am looking for the ultimate design, if there is such a thing.
