Design of CNTFET-based reconfigurable logic gate

Abstract

Described is a dynamically reconfigurable 8-function logic gate with seven double-gate carbon nanotube field-effect transistors which demonstrates p-type or n-type behaviour depending on the back-gate voltage. Through simulations, the gate is shown to operate at 20 GHz and has been used to build a 1-bit pipelined full adder using physically identical reconfigurable cells.
