JELE_V3_N3_RP6 Y. Varthamanan V. Kannan Journal on Electronics Engineering 2249 – 0760 3 3 27 31 CNTFET, Demultiplexer, Reversible Logic, Power This paper discuss about the CNTFET influence on the performance of the 4X1 multiplexer. Power analysis has been performed using HSPICE simulation software and the results are obtained for the 2X1 and 4X1 multiplexer transient behavior and the power consumption obtained is 0.8 and 1.6 nano watts respectively. Comparative analysis has been performed with the conventional demultiiplexer design to validate the proposed design performance. March – May 2013 Copyright © 2013 i-manager publications.
