Abstract :
This paper describes a dynamically reconfigurable 8-function logic gate (CNT-DR8F) based on a double-gate carbon nanotube field effect transistor (DG-CNTFET). The design is based on a property specific to this device: ambivalence, enabling p-type or n-type behavior depending on the back-gate voltage. Using available models, CNT-DR8F is proposed, simulated and analyzed at 20 GHz operation. We also give an example functional block (full adder) to show how to construct logic circuits based on the association of physically identical reconfigurable logic cells.
