Abstract
Integrated circuit chips with two (or more) multi-element logic paths--suffering from signal skew operation because of semiconductor processing variations--can be made to exhibit substantially reduced skew by designing the elements such that the sum of the pull-up delays in one logic path is approximately equal to the sum of the pull-up delays in the other logic path (or in each of the other logic paths) and such that the sum of all the delays (pull-down plus pull-up) in one path is substantially equal to the sum of all the delays in (each of) the other(s)--all in response to an input signal transition (low to high, high to low, or both) applied to each path.
