Programmable Logic Circuits based on Ambipolar CNFET

Recently, it was demonstrated that the polarity of carbon nanotube field effect transistors can be electrically controlled. In this paper we show how Programmable Logic Arrays (PLA) can be built out of these devices, and we illustrate how they outperform usual PLA by internal signal inversion. The simulations show an area saving up to approximately 21% and decrease of the delay in PLA-based FPGA by 50%. We also show that this architecture is suitable for high-performance design tools and defect-tolerance approaches.
