Abstract

The delay of the recently proposed Quantum-dot Cellular Automata (QCA) adders depends on the operand size and the architecture complexity. In this work we propose a QSDN adder. The preliminary results show that this adder is faster than the current QCA adders when considering large word length. Moreover the adder delay is independent of the operand size and it is estimated to be equals to the delay of one QSDN full adder.
