Design of a cmos full adder
WebSep 24, 2024 · For computational arithmetic, a full adder is the primary logic units in VLSI applications. A new full adder circuit design has been presented in this article which is based on input switching activity pattern and gate diffusion input (GDI) technique. The adder has been designed in two stages. The first stage is an XOR–XNOR module, whereas, … WebApr 24, 2024 · Vahid Foroutan, Keivan Navi and Majid Haghparast presented a new low power dynamic CMOS 1-bit full adder cell by eliminating the time consuming XOR gates from the design. They also tell that with the lowering of threshold voltage in ultra deep submicron technology, lowering the supply voltage appears to be the most eminent …
