This 2-bit adder was a lot of work to build. It uses a total of thirty-six 555 timers and it does have the option of adding or subtracting numbers.

2-bit binary adder made using 2 half adders INTRODUCTION A binary Adder is a digital circuit that performs arithmetic sum of two binary numbers provide with any length. A binary Adder is constructed ...

We report carry and sum circuits for a 2-bit adder. The 2-bit adders are designed to be part of a pipelined 2N-bit adder-accumulator. The ICs clock at a maximum of 19 GHz and were fabricated in InAlAs ...
