1.Domino logic is used to facilitate the cascading between the dynamic logic gates

2. Why is Dynamic logic gates used.

Dynamic logic gates are used in high performance datapaths and they are

glitch free.Glitches do not occus in dynamic logic.Why so? Because only one transition is possible during the evaluation stage and glitches are nothing but multiple unwanted transistions.

3.Glitches consume a lot of power

Switching activity factor is more for a dynamic logic gates

4.Charge sharing is also one major problem in dynamic logic gates which can be avoided by precharging the node to value of Vdd.

5.While choosing the logic style the following factors should be taken into consideration

a.Performance

b.Area

c.Power consumption

No logic style can do justice to all these three parameters
