In this paper, two novel low-power and high- speed carbon nanotube ... tube transistor, dynamic full adder, low power, high speed
Introduction
Carbon nanotube field-effect tran sistors (CNFETs) are
one of the new devices for designing low-power and
high- performance ... static power consumption, the
speeds of switching are high, and the voltage levels are
full swing. Dynamic logic style has also disadvantage of
high switching activity [10].
