Les portails dynamiques ont été un excellent choix dans la conception de modules haute performance dans les microprocesseurs modernes. La seule limitation des portails dynamiques est leur marge de bruit relativement faible par rapport à celle des portes CMOS standard. Traditionnellement, ce problème a été résolu en utilisant un circuit de gardien pMOS qui compense le courant de fuite du réseau nMOS déroulant. Dans les nœuds technologiques antérieurs, le circuit gardien pourrait améliorer la fiabilité des portes dynamiques avec une pénalité de performance mineure. Cependant, les tendances agressives de la technologie CMOS ainsi que les niveaux croissants de variations de processus ont réduit l'efficacité de l'approche traditionnelle Keeper. Ce problème est plus grave dans les portes dynamiques à large ventilateur en raison du grand nombre de dispositifs nMOS qui fuient connectés au nœud dynamique. Dans ce travail, une porte OU dynamique large tolérante aux variations de processus avec deux nouveaux modèles de gardien est proposée qui sont capables de réduire la controverse entre le gardien et le PDN et donc capable de réduire la dissipation de puissance et le retard.

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Dynamic gates have been excellent choice in the design of high-performance modules in modern microprocessors. The only limitation of dynamic gates is their relatively low noise margin compared to that of standard CMOS gates. Traditionally, this issue has been resolved by employing a pMOS keeper circuit that compensates for leakage current of the pull-down nMOS network. In the earlier technology nodes, the keeper circuit could improve reliability of the dynamic gates with minor performance penalty. However, aggressive scaling trends of CMOS technology along with increasing levels of process variations have reduced effectiveness of the traditional keeper approach. This problem is more severe in wide fan-in dynamic gates due to the large number of leaky nMOS devices connected to the dynamic node. In this work a process variation tolerant wide fan-in dynamic OR gate with two new keeper designs is proposed which are capable of reducing the contention between the keeper and PDN and hence capable of reducing the power dissipation and delay. 80 pp. Englisch.
