Exact group delay sensitivities for minimization of delay and distortion in high-speed VLSI interconnects

The authors present an alternative approach to minimization of transient responses such as delay, distortion and crosstalk by using frequency domain information such as group delay. A technique for efficient computation of exact group delay and its sensitivities is derived for multiconductor transmission line networks. The group delay information is combined with gradient-based minimax optimization to minimize delay and distortion in high-speed VLSI interconnects.<>
