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. It’s a rather unorthodox use of the part ...

By integrating contemporary semiconductor technologies, such as Complementary Metal-Oxide Semiconductor (CMOS ... bit configurations [2]. Comprehensive investigations that benchmark multiple full ...

but it really is just a half-adder and full-adder piped together in exactly the same way it would be wired up with CMOS or TTL gates. The video below shows it in action. If [Aliaksei]’s name ...

In this paper, the authors present a design of Full Adder circuit using AVL techniques for low power operation. The approach for the design is based on XOR/XNOR & Transmission gate for single bit ...
