Inthis paper we present the ternary logic gates implementation using FGMOS (Floating gate MOSFET) also calledMIFG MOSFET (Multi input floating gate MOSFET). Implementationusing ternary logic have advantage than binary logic implementation in terms of more information capability, reduced interconnections and reduction in chip area. MIFG MOSFETs design reduces transistor count as a result area of chip will reduce. Ternary logic gates using MIFG MOSFETs reduces transistor count compared with CMOS design and CNTFET based designs. Keywords-FGMOS, MIFG MOSFET, Ternary logic, Binary logic, CMOS and CNTFET.
