My project need a class D
Vin from 2.2v to 5v, Po=3watt 8ohm loading, capless.
I an a newer, need experienced engineer help for that:
1) loop analysis?
2) how to design feedback circuitry?
3) how to design EA, and compensation?
4) how to design the main comparetor?
5) any thing eles?
 

We had layed out Pre_Amp a part of Class-D.
With that experience i ll suggest you some of key points.

>Differential pair should be perfectly matched.

>All the MOSFETs with common drive(Gate) should be matched and all should be near.

am i making sense to u.. bcoz i jus layed out the pre_amp not designed.

If u wan more abt layout ask.
