Circuit design is the basis of design of demultiplexer. speed, power and chip area are the main factors that should be considered in circuit design. every circuit structure has its merits and drawbacks, e. g. cmos logic family has a slower speed, but lower power, smaller area, scfl ( source couple fet logic ) family has a higher speed, but higher power, larger area. we should choose a proper circuit structure or their mixed structure for certain design to get a good tradeoff among the three factors. flip - flop is the fundamental element of demultiplexer, setup time and hold up time are key factors, which influence the speed of circuit, thus the design aim is how to reduce them. in this thesis we place emphasis on the design of scfl latches
