Power analysis of TH23 null conventional logic

The most important logic unit in asynchronous circuit is null conventional logic unit. A new technology called semi-static threshold gate is used for realization of null conventional logic unit. In this paper TH23 NCL gate is designed in both semi-static and static style. These are implemented in tsmc 180nm process with minimum 1.8V power supply. Power analysis is performed for both type of style. From this analysis it is clear that power dissipation of semi-static style is less as compared to static style.
