Abstract

Performance of adiabatic carry look ahead adder using dynamic CMOS are studied and compared with Adiabatic carry look ahead adder using Pass Transistor. adiabatic carry look ahead adder using pass transistor has higher delay and lower power consumption while adiabatic carry look ahead adder using dynamic cmos logic has lower power dissipation and higher speed. adiabatic carry look ahead adder using dynamic cmos are design using 180 nm cmos technology and compared power dissipation and delay with respect to supply voltage and frequency. simulation result show that power dissipation of carry look ahead adder using dynamic cmos has higher performance comparison adiabatic CLA using pass transistor. simulation result show that adiabatic CLA using dynamic cmos reduce the power consumption 45% and delay reduce to 70% comparison to adiabatic CLA using pass transistor.
