As CMOS technology reaches its limitations, novel nano-electronic devices like Carbon Nano Tubes, Single Electron Transistors, and Quantum Cellular Automata are expected to take over CMOS devices in the near future. Of these many alternatives, Quantum Cellular Automata (QCA) has shown promise as a viable technology for future nano devices. Small device size, ultra low power consumption, and extremely high device operation speeds are some of the outstanding features of QCA which may lead this technology to replace CMOS. In this research paper, we present novel QCA design models and simulation results for FPGAs using QCA technology.
