Dear Zhangkun:
What tool did you use for your power noise simulations?
How close (relative to the associated component) did you place the decoupling 
caps?

Thank you.

Abe

Dear All:

In our simulation and measurement, we found that power noise of at least 400MHz 
could be decoupled by discrete caps. The placement DOES matter the impedance of 
PDS. The current problem is the anti-resonance between different kinds of caps.
