چکیده
In this research paper, Simulation and Analysis of innovative folded cascode Operational Amplifier based on carbon nanotubes (CNT) has been performed using 45 nm technology. DC voltage gain, average power, bandwidth and output resistance have been computed. CNT based folded cascode Op Amp results in high performance with the increase of CNTs. For example, the increase in DC gain is 41.48% in pCNT based folded cascode Operational Amplifier and 13.93% in nCNT based folded cascode Operational Amplifier; decrease in average power is by 16.86% in pCNT based Operational Amplifier and 55.42% in nCNT based folded cascode Operational Amplifier in comparison to CMOS based folded cascode Operational Amplifier respectively. However, the output resistance has decreased in CNT based FC-OP AMP in comparison to conventional CMOS based Folded Cascode OP AMP. The low output resistance has resulted in a small bandwidth in CNT based FC-OP AMP. Further, the simulation studies have revealed that the performance of the CNT based folded cascode Op Amp can be improved optimized at different CNTs.
