sovadk said:Sourcing a amp with a current source makes no sense. I think it's placed there to model some feture rather than being the actual design. The MOSFET's are configured in a H-bridge. You can't avoid the need for deadtime with this configuration.
Placing an inductor on the supply can prevent large shoot through currents, but will intruduce a lot lot of ringing and most likely worsening things rather than improving anything.
You can avoid large deadtimes by selecting proper transistors with low gate charges. FDD3682 or IRF6665 can be recomended.
A deadtime about 10ns will produce arround 0.1% THD. Sinse 10ns deadtime is hard to achieve, theres no way arround a bit of open loop distortion. A self osccilation design controls the outputstge cycle by cycle and removes some of the errors. Feedback should also be applied.
