A full adder is one of the most commonly used digital circuit component, many improvements have been made to refine the architecture of a full adder. So far, the full adder of 10-T (transistors) architecture is considered as the most balanced design regarding performance and area. However, the era of deep sub-micron CMOS process has come which makes the traditional 10-T designs not applicable in the mentioned CMOS process. In this paper, 5 different types of 1 bit full adder 28T, 10T, 14T, Modified 14T and 12T adder is compared based on different parameters.
