This paper proposes novel triangular cross-sectioned geometry of carbon nanotube (CNT) bundles for crosstalk and delay reduction in CNT bundle interconnects for VLSI circuits. First, we formulate the equivalent single conductor (ESC) transmission line models of the interconnects. Through SPICE analysis of the ESC circuits, we find the propagation delays of the proposed CNT bundles. Next, we model the capacitively coupled interconnects for crosstalk analysis. It is found that the coupling capacitance of triangular CNT bundle is 29% lesser than the traditionally used square CNT bundles. Further, the crosstalk-induced delay of triangular interconnects is found to be 30% lesser when compared to square bundle interconnects. The reduction in delay is found to increase as the number of CNTs in the bundle increases. So, we suggest that triangular CNT bundles are the most suitable candidates as global interconnects.
The present work explores the potential of tea fibre waste as an adsorbent to remove phenol and nickel from wastewater in both single and binary component mode. The properties of the tea fibre such as surface area, pore volume and particle size were improved by treating with hydrochloric acid. The isotherm models were verified for single component system to find the adsorption mechanism. The equilibrium data were obeying Freundlich model. The simultaneous adsorption of two pollutants were carried out in order to evaluate the interaction mechanism such as synergic, antagonistic or non-interaction effect. It was observed that overall the system was exhibiting synergistic type of behavior.
This paper proposes novel triangular cross sectioned geometry of carbon nanotube (CNT) bundles for crosstalk and hence, delay reduction in CNT bundle interconnects for VLSI circuits. We formulate the equivalent single conductor (ESC) transmission line models of the interconnects and
show that the coupling capacitance of triangular bundle is 29% lesser than the traditionally used square bundles of carbon nanotube interconnects. We further simulate the proposed ESC models of capacitively coupled CNT bundle interconnects using Smart SPICE and find that the crosstalk induced
delay of triangular interconnects is 30% lesser as compared to square bundle interconnects. The reduction in delay is found to increase as the number of CNTs increase in the bundle. From these results, we suggest that triangle cross-sectioned CNT bundles are the most suitable candidates as
global interconnects.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
