The design consisted of modular components, utilizing a 1-bit Full Adder as the building block. These Full Adders were cascaded to handle the 4-bit addition, producing a 4-bit sum output and a carry ...

4bit-adder 4bit adder and Subtractor As we learned from DLD course, we can build 4bit adder by cascading four 1bit full-adders. So in this Assignment I preferred to build every component from the ...

A 4-bit ripple carry adder in QCA is then designed using the proposed Feynman and Toffoli gates to realize a reversible QCA full adder. This 4-bit QCA adder with reversible logic consists of 2030 QCA ...

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.

He decided to do that by creating a 4 bit full adder. We know this is pretty useless in everyday life, but it was a great learning experience. The beauty of this adder is right at the start.
