  Complementary metal oxide semiconductor technology (CMOS) has been faced
critical challenges in nano-scale regime. CNTFET (Carbon Nanotube Field effect
transistor) technology is a promising alternative for CMOS technology. In this
paper, we proposed a novel 7-input minority gate in CNTFET technology that has
only 9 CNTFETs. Minority function is utilized in the voting systems for
decision making and also it is used in data mining. This proposed 7-input
minority gate is utilized less fewer transistors than the conventional CMOS
method which utilizes many transistors for implementing sum of products. By
means of this proposed 7-input minority gate, a 4-input NAND gate can be
implemented, which gets better the conventional design in terms of delay and
energy efficiency and has much more deriving power at its output.
