Abstract
Reversible logic has become increasingly important in the design of low power CMOS circuits, quantum computing and nanotechnology. In this article we work on recent sequential circuits namely RS Flip Flop JK Flop Flip Flop Flop Flip Flop Master Slave Flip Flop using some reversible gates FG (Feyman Gate), FRG (Fredkin Gate), NG (New Gate) , PG (Peres Gate), BJN (New BJN Gate), while modifying them to obtain new circuits keeping their same functionality and increasing their performances.
Highlights
In the irreversible circuit each lost bit generates a loss of heat described by KTln2 joules of or K: Constant of BOLTZMAN T: Absolute temperature related to the computation, Formula established by Landauer [1] .In the reversible case Bennett showed that this said quantity heat would not occur [2], the proof is that this amount of heat is related to the number of bits lost in an irreversible circuit
In this paper we exploit a recent study to design reversible sequential circuits that can perform more delicate operations using quantum computers using certain reversible gates namely Feyman Gate (FG), Fredkin Gate (FRG), New Gate (NG), Peres Gate (PG) and New BJN Gate (BJN) [3,4]. we designed sequential circuits synthesized by the reversible logic namely RS, JK, D, T and Master Slave Flip Flop while improving performance and obtaining better results
After moderating the exploited circuit, replacing NG by PG and keeping the same functionality, we got our proposed design (Fig 11).the Table 2 shows an evaluation of the proposed D Flip Flop design and the improved results obtained with this moderation
