Realization of combinational logic circuits using standard functions in quantum dot cellular automata

Аннотация

A set of functions commonly used in basic circuits are defined as standard functions. They are so called because different combinations of different logic circuits are designed using these functions. They are also used to realize combinational logic circuits and most Boolean expressions. In this paper, 13 standard functions are discussed with their various applications using Quantum Dot Cellular Automata known as QCA which is currentlya familiar nanotechnology for its ultra-low power consumption and high speed operations. The designed functions are analyzed with area, latency and cell count. Energy calculations have been done with the suitable input for its stable operation. Algorithms are also established for the designed functions to realize in QCA technology.
