Zusammenfassung
This paper presents 1-bit full adder cell in emerging
technologies like FinFET and CNFET that operates in the
moderate inversion region for energy efficiency, robustness
and higher performance. The performance of the adder is
improved by the optimum selection of important process
parameters like oxide and fin thickness in FinFET and number
of carbon nanotubes, chirality vector and pitch in CNFET.
The optimized CNFET-based full adder (OP-CNFET) has
higher speed, lower PDP (power-delay product) and lower
power dissipation as compared to the MOSFET and FinFET
full adder cells. The OP-CNFET design also offers tight spread
in power, delay and PDP variability against process, voltage
and temperature variations. All the evaluations have been
carried out using HSPICE simulations based on 32 nm BPTM
(Berkeley Predictive Technology Model).
