چکیده
Continuous scaling of the transistor size and reduction of the operating voltage has led to a significant performance improvement of integrated circuits. Low power consumption and smaller area are some of the most important criteria for the fabrication of DSP systems and high performance systems. In this paper there is try to determine the best solution to this problem by comparing a few adders. In this project when we compare the supply voltage of all the adders by same width and minimum length of 0.18μm, it has been concluded that when there is minimum supply voltage of different adder then minimum average power is consumed, When we increase the power, we find that carry look ahead and Carry bypass adder consume more power when its supply voltage are same. The conventional full adder is built by 28 transistors. So, the transistor count is very high. The average power consumption and delay is very high. In this paper a new circuit which is made by mainly the TG technology. For the purpose of comparative analysis of TG based 16-bit different adder Design using 180nm technology, we use TANNER tool. Keywords— Ripple Carry Adder, Carry Look-ahead adder, Carry Bypass Adder, TG based CMOS Logic Design Style.
