Now-a-days in digital circuit design low power and small area are main issues of concern for VLSI designers. GDI (Gate Diffusion Input)-a technique of low power digital combinational design. This technique as compare to other currently used logic design styles, allows less power consumption and reduced propagation delay for low-power design of combinatorial digital circuits with minimum number of transistors. But this basic Gate Diffusion Input (GDI) logic style suffers from some practical limitations like swing degradation, fabrication complexity in standard CMOS process and bulk connections.
