This lecture presents collaborative work between EPFL and CEA on designing complex architectures using controllable polarity devices, focusing on carbon nanotube technology. The speaker introduces assumptions, such as ambipolar CNT technology and double gate channel control, leading to the development of logic gates with high configurability. The lecture explores the concept of generalized NAND NOR structures and AND OR inverter gates, showcasing their versatility in realizing various logic operations. It then delves into the comparison of these gates with CMOS technology, highlighting the advantages of the proposed approach. The discussion extends to FPGA architectures, proposing a novel design with unbipolar gates and configurable signal polarity. Results from the evaluation of different granularity levels in logic gates demonstrate improved performance in terms of delay, albeit with a slight increase in area. The lecture concludes by emphasizing the potential of these new logic operators for both ASIC and configurable logic applications.
