Novel Approach to Analyze Crosstalk for a Multi-Line Bus System at 32-nm Technology

Abstract

This research paper presents a novel approach to analyze the crosstalk-induced delay of multi-layered graphene nanoribbon (MLGNR) and multi-walled carbon nanotube (MWCNT) interconnects. A multi-line driver-interconnect-load (DIL) system is employed to analyze the crosstalk-induced delay for different switching transitions. The interconnect lines of the proposed DIL are said to be operated by either a resistive or a CMOS, or a CNFET driver for different switching transitions at 32-nm technology. Using the unique CNFET driver, the victim line of the multi-level MLGNR/MWCNT-based bus system experiences a delay almost 57.25% and 31.62% lesser in comparison to a resistive driver and a CMOS interconnect driver, respectively. Additionally, the overall worst-case delays are reduced by 89.45% and 98.98% for MLGNR in comparison to an equivalent MWCNT at 100[Formula: see text][Formula: see text]m and 1,000[Formula: see text][Formula: see text]m interconnect lengths, respectively.
