Dynamically reconfigurable logic gate cells and matrices using CNTFETs

This paper describes a family of novel dynamically reconfigurable logic gates with double-gate carbon nanotube field-effect transistors (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. Through simulations using available models, these gates are shown to operate at 4 GHz. We subsequently compare these cells to conventional CMOS look up tables, and demonstrate how they can be used in matrices to achieve complex logical functions.
