| Abstract | QCA adders are fundamental building blocks of complex QCA computational units. In our analysis, we show that QCA ripple-carry adder and bit-serial adder designs actually outperform carry-look-ahead and carry-select adder designs. The QCA ripple-carry and bit-serial adders require fewer clocking zones, which have been found to be the main contributing factor toward overall circuit latency. |
