Hello,

I am working on the electrical modeling of different aspects of a 
wireless sensor node packaged using a system in a package approach. 
The sensor node is packaged in a way that you have RF/micro 
controller/sensors/power management/battery all in close proximity. 
My question is this: are there any signal integirty issues arising 
from the fact that the device is mixed signal and battery powered? Is 
it enough to follow 'good' power supply network practices/guidelines 
for each individual section or block of the system- 
(bypassing/decoupling etc), keeping the power/ground seperate and 
tying them together at the battery?.
