Reducing Noise

When I was doing serious electronic in the 70's I found that transistor noise was a pain. This was made worse when two or more transistors were in close proximity and I resorted to tuning out the noise with small inductors.

Translating this in to nano-tech could require designing ample spacing out of transistors and perhaps developing nano-inductors.

Interestingly I found that the best attenuated square wave peak was when there were only three connections: signal in; ground and signal out. You may well ask what about the positive power connection? The answer is that it is not necessary when clocking at high frequencies as the signal in connection provides the positive potential.

Splitting the signal in with phase shift could provide even greater stability as noise is cancelled out. This is is the same principal as noise cancelling headphones.

This is an oversimplification and would require greater explanation but is all about adapting known strategies.
