phy analog ground
To keep digital noise from interfering with analog signals, we may seperate analog ground from digital one, and then connect them at one point or via ferrat beans.
But this way will increase ground impedence. So recently, I always combined these two grounds, especially in high speed design.
So when we need seperate ground plane?Are there any advice?
