Proposed Title :

A Novel Design of Flip Flop Circuit Using GDI Logic

Improvement of this Project:

• • To Design a Different types of flip flops such as SR, D,T and JK flip flops using GDI logic.

  • To implement these flip flops in TANNER in 45 nm CMOS technology at 1.8V supply voltage and compared the area, power and delay.

Software implementation:

• TANNER EDA

Proposed System:

Quantum Dot Cellular Automata (QCA) is a transistor less quantum paradigm that represents the binary information which is based on spatial distribution of electron charge computation and routing information at nano domain. This paper proposes the new design concept of different flip flops which includes SR, D, T and JK in GDI(Gate Diffusion Input) logic.  The existing system uses the concept of QCA technology to implement these flip flops, but it consumes more area, power and it also faces the complexity in hardware implementation. This technology has a surface defects, which can affect the combination of electrons and holes in the circuit. Therefore this paper proposes the concept of GDI technique in order to reduces the area and design complexity. Thus, the proposed system of GDI Technique flip flops reduces the area, power and hardware complexity when compared to existing system of flip flop design using QCA logic. The proposed system has been implemented in 45nm CMOS technology at 1.8V supply voltage and shown the comparison in terms of area, power and delay.
