Ambipolar double gate CNTFETs based reconfigurable logic cells

Published: 04 July 2012 Publication History

Abstract

This paper presents 2-input cells designed to perform reconfigurable operations in nanometric systems exploiting the ambipolar property of double-gate (DG) carbon nanotube (CNT) FETs. Previous work [12] described a dynamic logic cell generating only 14 functions instead of 16 normally performed by the multiplexer-based logic part of a CLB (Configurable Logic Block) of an FPGA for 2-inputs.
In this work, a reconfigurable 2-input dynamic logic cell designed using DG-CNTFET devices is able to achieve a more complete set of functions by exploiting sum of products (SOP) and product of sums (POS) to express logic functions. We also demonstrated that a static logic version can be derived from this dynamic cell. Simulations reveal improvement factor of 3X in terms of delay and 23% of decrease in power consumption compared with the previous work [12]. When compared with 16nm-CMOS Technology, DG-CNTFET cells (dynamic logic and static logic style) showed a comparable PDP with a slight increase in area.
