Conclusion

After this very brief introduction to several CMOS families, we chose two different logics, in order to apply the study of the optimization techniques objects of this thesis. The criteria that drove us in choosing these families was both the diffusion in VLSI circuits, and the presence of very good qualities, perhaps not yet fully exploited in the real production of circuits.

For these reasons we have chosen to include in our library a few static gates (an ``and'' gate, an ``or'' gate, and a few more) and a few dynamic gates, and in particular gates from the TSPC family. This family has shown good characteristics in term of speed, area occupancy and power dissipation; it has also the very important feature to need only a single clock.

The complete list of the gates comprising the library can be found in the table 7.1 (page ), with their relative schematic diagram of CMOS implementation.
