Hello, who never heard of noise in integrated circuits(IC)..!...white noise,Gaussian noise, flicker noise, 1/f noise and so many different terminologies. I can talk about NOISE and make some noise and I agree that I don't know exactly about what are these dirty noise in my systems is. However, there are noise in systems which are internal to the system and some which are influenced by the external world like-another circuit besides it, environmental radiations etc.
I have a confusion -whether noise is positive or negative with respect to ground?
We operate circuits with positive supply(with respect to ground).NB:ground is decided by the battery and not by circuit). However, it is important to have proper ground and supply connection to a circuit.
If we operate a circuit (say CMOS inverter) with following topology(shown in image right side one),do we get any advantage over the noise performance?
No doubt, the input of for the new topology also be need to change with respect new reference.However, are we achieving any thing good here. It is one of the thought in opposite to classical definition of reference and ground.
Let me know your views. Comment please.

Well, its fine but what i know is we have to stick to a certain standard, define new one only if it is required. use of Positive supply is well settles standard then what is the reason we go for new one if we dont have the advantage?
