A Novel Low Power Dynamic Barrel Shifter using Footed Diode Domino Logic

The choice of the complementary metal oxide semiconductor (CMOS) logic to be used for implementation of a given specification is usually dependent on the optimization and the performance constraints that the finished chip is required to meet. Dynamic logic provides better performance for higher fan in and complex logic circuits and also with the increasing level of integration, high speed and low power dissipation have become the mandatory requirements for any logic design along with the performance. Many design logics are available within Dynamic Logic stream. One of the popular logic is the Domino logic for low power dissipation and high speed. This paper presents a comparative study and analysis of Barrel Shifter using Pseudo nMOS multiplexer and Footed Diode Domino(FDD) multiplexer.
