An Efficient CNTFET Based 7-Input Minority Gate

Complementary metal oxide semiconductor technology(CMOS) has been faced critical challenges in nano-scale regime. CNTFET (Carbon Nanotube Field effecttransistor) technology is a promising alternative forCMOS technology. In this paper, we proposed a novel7-input minority gate in CNTFET technology thathas only 9 CNTFETs. Minority function is utilized in the voting systems for decision making and also it isused in data mining. This proposed 7-input minoritygate is utilized less fewer transistors than theconventional CMOS method which utilizes many transistors for implementing sum of products. By means ofthis proposed 7-input minority gate, a 4-input NANDgate can be implemented, which gets better theconventional design in terms of delay and energy efficiency and has much more deriving power at itsoutput.
