Gate delay calculation considering the crosstalk capacitances

In this paper, we present a new technique for calculating the output waveform of CMOS drivers for cross-coupled RC loads. The proposed technique is based on an effective capacitance calculation for each driver and an efficient, provably convergent, iterating scheme between the coupled drivers. Our technique can easily handle different input arrival times, transition times, and polarities, and can be extended to multiple cross-coupled drivers in a straightforward manner. Experimental results show that the new technique exhibits high accuracy (less than 4% error in average).
