Abstract
The performance of the adder entirely influenced by the performance of its basic modules. In this paper, a new hybrid 1-bit 14 transistor full adder design is proposed. The proposed circuit has been implemented using pass gate as well as CMOS logic hence named hybrid. The main design objective for this circuit is low power consumption and full voltage swing at a low supply voltage. As a result the proposed adder cell remarkably improves the power consumption, power-delay product and has less parasitic capacitance when compared to the 16T design. It also improves layout area by 7–8 % than its peer design. All simulations are performed at 90 & 45 nm process technology on Synopsys tool.
