CROSSTALK NOISE AND DELAY REDUCTION IN VLSI INTERCONNECTS

Crosstalk in interconnects had a great impact on overall reliability and performance of IC and thus it plays a key role in deep submicron (DSM) VLSI circuits.In this paper schmitt trigger is designed as a buffer which operates at a 20 GHz frequency so as to minimize crosstalk noise and delay in interconnects. In order to propagate the signal with the reduced noise and delay simultaneous buffer and wire sizing is done along with buffer insertion through interconnects .Accurate SPICE results shows that at 90nm technology node crosstalk noise is reduced by 60% and delay by 56% for 1V power supply.
