In this paper a hybrid GDI based 9T full adder and 4-bit ripple carry adder (RCA) are designed, which reduces power consumption and area of digital circuits while maintaining low complexity of logic ...

In this paper design of 4-Bit ripple carry adder is proposed using a CMOS full adder cell. Multiple full adder circuits can be cascaded in parallel to add an N-bit number .For N-bit parallel adder , ...

This paper focuses on the implementation and simulation of 4-bit, 8-bit and 16-bit carry look-ahead adder based on Verilog code and compared for their performance in Xilinx.

Using the reconfigurable logic of multi-input floating gate MOSFETs, 4-bit full adder has been designed for 1.1V operation.
