Abstract :
In this paper a new high speed and low power adder is presented. The circuit uses a hybrid concept of analog and digital circuit design to propagate the carry and so achieve a Full Adder with 78 ps delay and 7.26 muW of power consumption. SPICE Simulations performed on the 0.18 mum TSMC Technology demonstrates the average improvement of 159%, 184% and 516%, respectively for delay, power consumption and PDP.
