TT: <<<The low K is thus extremely important at all frequencies. Low K will increase the performance of all the gates in the chain.>>> You are wrong TT. The impedance of a capacitor is 1/(jwC) where w=2Pifrequency and C=capacitance. At high frequency the impedance between the metal lines act like a "short" and starts to crosstalk. At low frequency low K is unimportant. Even in FET the term such as Miller capacitance becomes a killer at high frequency. Maxwell
