Abstract: In this paper, a Johnson up-counter was designed by using the different types of flip flops. Here the D-flip flop was designed using the DML type_A NAND gate, and TSPC flip flop using the DML( Dual Mode logic) logic inorder to reduce the power dissipation. The TSPC_DML flip flop has less power compared to the D-flip flop. The Dual Mode Logic (DML) family provides a novel approach to providing this capability by introducing two configurable operating modes, static and dynamic. The dual mode logic gates has very low-power dissipation with moderate performance in the static mode of operation.The proposed TSPC D-flip-flop in which the number of transistors are reduced from 11 transistors to 5 transistors. As number of transistors are reduced in occupies less area and also the power will be reduced compared to the conventional TSPC (True single phase clock) D-flip-flop.
