Abstract: 32-bit serial and parallel adders exploiting minority-3 elements and inverters only, are presented, including chip measurements. The implementation is done in a standard triple-well 90 nm ...

Abstract: Two designs of 10-transistor 1-bit adder are described in this paper. The output voltages levels of these 1-bit adders have a maximum of one threshold voltage (V/sub T/) loss. This is an ...

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, depending ...
