In general interconnects in vlsi circuit causes many variations and delay in the circuit. Process variationsand circuit aging continue to be one of the main challenges to the power-efficiency of VLSI interconnect circuits. Notonly Power efficiency, circuit delay and area also causes major effect in the vlsi interconnect circuits. To overcome theseeffects repeaters are used in the vlsi circuit to provide a better performance. Boostable Repeater design can transientlyand autonomously raise its internal voltage rail with its boost switching speed. It achieves fine-grained voltageadaptation without stand-alone voltage regulators or an additional power grid and has plenty of chances to improvesystem robustness. The boosting can be turned on/off to compensate variations. There are mainly two approaches forvariation compensation: Adaptive body bias(ABB) and supply voltage adaptation .An adaptive design provides a powerefficient approach to variation tolerance. The proposed technique is the Boostable Repeater design with DualASV(Adaptive supply voltage).The dual ASV can simultaneously provide adaptive supply voltage at both coarse-grainedand fine-grained level, and has limited power routing overhead. The existing technique provides only fine-grainedvoltage adaptation where as the proposed technique provides both fine-grained and coarse-grained voltage adaptation.
