Abstract-- Carbon nanotubes (CNTs) have superior transport
properties, excellent thermal conductivity, and high current
handling capability; recently the CNT has been proposed as an
alternative device technology to supersede CMOS. In this paper,
the circuit-level performance of CNT-based FETs (CNTFETs) is
initially compared to MOSFETs; simulation is performed for
various logic gates and benchmark circuits to assess the
sensitivity to PVT variations using the same minimum gate length.
