Integrated circuits (IC’s) are sized for higher performance and packing density. Interconnects are major components to carry signals between transistors. Interconnect delay increases due to increase in length of interconnect. Optimization of interconnects is more essential to
improve the performance of integrated circuits. Repeater insertion is an important technique used in optimizing the performance of interconnects in integrated circuits. Repeaters have to be designed to satisfy the performance constraints. In this paper we have designed a new repeater using
transistors and analyzed the performance at various bias levels. The Repeater design was implemented at various technology nodes using PTM models and Bulk CMOS. Delay and power dissipation are analyzed for various voltage levels and load levels using Spice simulations. The results show that
the proposed repeater has lesser delay compared to the conventional repeater with an increase of power dissipation and they are more suitable for Critical path in VLSI interconnects. They can be applicable for CNT based VLSI interconnects.
