English Abstract
Abstract :
1-bit full adder is a very great part in the design of application particular integrated circuits. Power consumption is one of the most significant parameters of full adders. Therefore reducing power consumption in full adders is very important in low power circuits. In this paper, we propose two new structures of hybrid full adders. The first full adder implemented by combining the Swing Restored Lass-transistor Logic and Branch-Based Logic that called, SRPL-BBL cell and the second full adder implemented by combining the Gate-Diffusion Input technique and Majority function that called, GDI-Majority cell. All of the capacitors in this paper replaced with MOSCAP. Simulation results performed by HSPICE in TSMC 0.13 μm CMOS process. The results indicate the superiority the proposed full adders against several low power 1-bit full adder cells in terms of delay, power consumption, and power delay product (PDP).
