Dynamic circuits for ternary computation in carbon nanotube based field effect transistors

摘要

As we continue downscaling devices, a number of nanoscale materials have been proposed as replacements for Silicon based devices. Carbon nanotubes have attracted widespread attention and numerous researchers have shown that digital circuits can be created using the field-effect properties of these nanoscale devices. This work investigates the design of multi-valued computation in carbon nanotube based field effect transistor (CNTFET). Using a Complete Model technique, we show that dynamic ternary logic can be implemented in CNTFET devices and that the delay and power-consumption of this approach is much lower compared to previous multi-valued implementations.
