Design and Analysis of Dynamic Current Mode Full Adder with reduced Power and Delay

Dr. S.R.P. Sinha | Namita Tiwari

Abstract: Current mode logic (CML) technology is popular as it offers high performance with very low power dissipation, equal charging and discharging times, equal noise margins and low output logic swing, therefore high-speed performance is achieved. In this paper, MOS current mode logic (MCML), dynamic current mode logic (DyCML) and cascaded dynamic current mode logic techniques are analyzed and applied to the generation of digital arithmetic circuits. Based on the presented analysis a new current mode full adder is proposed where the circuit of Dynamic Current mode full adder is modified. It is shown that in the proposed full adder circuit both the power consumption and delay time are reduced. The circuits are simulated using TANNER tool with 0.18m technology and supply voltage 1.5V.
