Abstract:


Background & Objective: In this paper, a modified pseudo domino configuration has been proposed to improve the leakage power consumption and power delay product (PDP) of dynamic logic using carbon nanotube MOSFETs (CN-MOSFETs). The simulations for proposed and published domino circuits are verified by using Synopsys HSPICE simulator with 32nm CN-MOSFET technology which is provided by Stanford. The simulation results of the proposed technique are validated for improvement of wide fan-in domino OR gate as a benchmark circuit at 500 MHz clock frequency. The proposed configuration is suitable for cascading of the high performance wide fan-in circuits without any charge sharing.

Results and Conclusion: The performance analysis of 8-input OR gate demonstrate that the proposed circuit provides lower static and dynamic power consumption up to 62 and 40% respectively, and PDP improvement is 60% as compared to standard domino circuit.
