For instance, the VBG is 1.2V, do we need to connect this node to decoupling cap to VDD, say 3.3V? I am afraid the cap will become an AC path for the VDD noise to couple into VBG. Any comments

But for some cases, the ground bouncing could be very serious. Connect decoupling cap to ground would also couple AC noise. How can we deal with it?
