This paper aims of designing of 4-bit ripple carry adder using various CMOS full adder circuits and comparing with various technologies of TSMC library. Full adder is used in various applications like signal processing, arithmetic operations, and multiplexers and so on. This defines the need and importance of designing an adder block in a viable manner. In this Performance is measured for both 180nm and 130nm technologies. For schematic design we are using pyxis schematic produced by mentor graphics. The comparative analysis of different adders is covered here with number of transistors or gate count, delay, average power and power-Delay-product. These are the first concern parameters for measuring of design performance. In ripple carry adder design to achieve best performance metrics various components like inverter, transmission gate, and pass transistors are used.
