Abstract: This paper proposes a new 16-bit adder which has a wide operating voltage range and higher energy efficiency for near-threshold voltage operation. This adder employs the architecture of ...

A Full Adder (FA) can only add two 1-bit numbers along with a carry input. However, in most digital systems, we need to add multi-bit binary numbers (e.g., 4-bit, 8-bit, 16-bit). A Ripple Carry Adder ...

The RTL design is found in the adder_32.v file, which defines the structural logic of the 32-bit adder. It takes three inputs: a, b, and cin, and produces two outputs: sum and cout. Internally, the ...
