..had the same feeling/thought first. And indeed the initial posting appears to be really far away from a dissertation. - But at least mousas17 seems to be honest about the purpose.
And somehow it is not worse compared to when somebody just copies and reassembles older papers/publications.
(
Please don't start beating me. I know or at least believe that most PHD titles are not derived just by copying and reassembling, but by a highly valuable combination of literature research and own contribution).mousas17:
Will your prof and the committee members to whom you finally will have to defend your thesis accept a forum as a valid scientific source?
If no, better stop this thread.
If yes: Run this thread as your official public interactive source and quote it correctly in your thesis. In order to generate some trust that you are not cheating, most likely many potential contributors would ask you for the a contact to your prof..
The general downside of such approach is that this thread might finally cover to many topics and aspects. And whenever someone posts something which you did not mention before you cannot state it any more as your own contribution, even if you had already worked out this knowledge on your own earlier.
Means such approach bears the risk, that you will have a hard time or even fail to prove enough of own contribution.
... but a Ph. D. is granted based on three years of well-documented and mostly independent research, right?
/U.
It depends very much on the discipline and country.
In Germany for physics and engineering disciplines I agree to your view.
...and no... I also did not go this path...
Unfortunately not? Or was it good luck for my life?
Will answer this only in a nice bar with some beer.
That"s the key question. Without any unpleasant boundaries it would be home run for free, at least in some operating points.
Current mode means you need to sense the output current (vs voltage), which is a little more complicated, and compensate accordingly if your load is complex.
Fundamentally a class D amp is a switching power supply, the same design techniques/equations/whatever that go into making a synchronous buck converter (or any CCM forward converter, for that matter) are applicable to a class D amp.
Only difference is that the reference voltage is the audio input, not a fixed voltage.

gmarsh!
I strongly agree with you in starting design with specification.
But specification must not include implementation details explicitely. So I also ask: why current mode?
And if it is really the part of the task, then which kind of current mode? Peak current? Average current? Or hysteretic? Fixed off-time? They are completely different!

Let's see what mousas17 is going to show.
So far zero contribution from his side - which triggers my pattern recognition.
It is a well known pattern. Just trigger the egos of the specialists and they will start to compete. After a short period of standard level discussions they will spread out their most inspiring ideas for free.
Classic group dynamics.
