ABSTRACT

Quantum Dot Cellular Automata (QCA) is an
alternative to CMOS technology. The other technologies proposed
by researchers are FINFET, CNTs and MTJ to reduce
scalability of CMOS devices.
Using Quantum Dot Cellular Automata, the low power,
extremely dense circuits are designed. QCA cell is the
Fundamental unit in building logic gates. These cells are powered
using specific clock.
QCA cells are used to design basic gates and to realize Boolean
expressions. QCA Designer tool is used to carry out simulations.
The simulation results are same as theoretical results. The
complexity and size of circuits are reduced using QCA. The paper
includes design of Programmable Logic Array (PLA).
Keywords: Boolean Expression, Clock, CMOS, Fundamental Unit,
QCA Designer
