This work proposes a testable QCA (Quantum-Dot Cellular Automata) logic gate (UQCALG) realizing the universal functions. The design of UQCALG is based on the Coupled Majority Minority (CMVMIN) QCA structure with the target to reduce wire crossings as well as the number of clock cycles required to operate a QCA circuit. The characterization of defects in such design leads to synthesis of a test block,...
Wire crossings limit the performance of a logic circuit in Quantum-Dot Cellular Automata (QCA) based design. Minimization of wire-crossings is, therefore, of prime importance in the current nanotechnology, susceptible to high error rates. This work proposes a QCA (Quantum-Dot Cellular Automata) logic gate (UQCALG) realizing the universal functions. The design of UQCALG is based on the coupled Majority...
