John,

Re: " If you get the higher frequency by increassing the current in the transistors (Idsat), then the power goes up as the square of frequency."

No John ... to increase the Idsat, you must either physically change
the FET (shorter Leff, Gate thickness, Source/Drain resistance ...) or
increase the voltage. As I pointed out, if you increase the voltage, then the
power goes as the square of the voltage change. You need to be careful
in your assumptions, John.

Make It So,
Yousef
