Shift Register Design Using Four and Eight Bit Flip-Flop

Abstract

A novel concept of multi bit flip-flops has been proved to be an effective way in processing multiple bits simultaneously .In this paper we propose a way of using multi bit flip-flop technique in designing various digital circuits. By sharing the inverters in the flip-flops, the total number of inverters can be reduced in a multi-bit flip-flop. So, here, we have designed a shift register which is an important memory element in digital systems, using 4-bit flip flop & 8-bit flip flop. Experimental results reveal that our approach is very efficient, which can be effortlessly incorporated in modern vlsi circuit designs.
