5- Extendable quantum-dot cellular automata decoder using 5-input majority gate

摘要

The present invention relates to a QCA decoder. The QCA decoder according to the present invention includes a first wiring for inputting a first input signal, a second wiring for inputting a second input signal, a third wiring for receiving an enable signal, a second wiring for transmitting a second input signal, A fifth wiring connected to the first wiring to transmit the first input signal, a sixth wiring and a ninth wiring connected to the second wiring so that a signal obtained by inverting the second input signal is transferred, A first wiring connected to the seventh wiring, a fourth wiring, a fifth wiring, and a third wiring connected to the first wiring so as to transfer a signal obtained by inverting the input signal, A seventh wiring, an eighth wiring, and an eighth wiring connected to the combinational logic cell, the fifth wiring, the sixth wiring, and the third wiring to perform a logical product gate function to output a second output signal. 3 wiring for outputting the third output signal by performing the AND gate function, A combinational logic cell, and a fourth combinational logic cell coupled to the eighth, ninth, and third wirings to perform a logical AND gate function to output a fourth output signal. According to the present invention, it is possible to provide a decoder having a scalable structure using a quantum dot cellular automata.
