Compact modeling and applications of Carbon nanotube field effect transistors CNTFETs based CMOS-like complementary NOR, OR, NAND, and AND logic gates

In this paper, CMOS architectures for NOT, AND, OR, NOR and NAND gates were proposed using C-CNTFETs and their operational characteristics were checked using the simulator SPICE. The CNTFETs utilize a semiconducting Carbon nanotube (CNT) channel controlled by isolated electrostatic gates. Circuit-compatible model of conventional CNTFET, which demonstrates p-type or n-type switching behavior depending on the gate voltage, is implemented in SPICE and the designs are extensively simulated in SPICE. The power and delay performance of CNTFETs were investigated in basic logic gates for D_CNT=1.42 nm on this SPICE model.
