In accordance with this law, over the decades, CMOS technology has been providing the required dimensions for implementing high speed, high density, and low power VLSI systems. Current studies project that the miniaturization of these devices will lead to negative outcomes such as power dissipation and electro-migration failures. This will result in diminishing returns in switching performance, diffusion barriers, gate depletion, stray capacitances and off-state leakage. In the past, researchers have focused on investigating alternative technologies at the nano scale to potentially replace CMOS technology in the future. As such, many emerging technologies including Single Electron Transistors (SETs), Spin Transistors, Resonant Tunneling Diodes (RTDs), and Carbon Nano Tubes (CNTs), and Quantum-dot Cellular Automata (QCA) are being investigated as potential candidates to replace conventional CMOS technology.This research deals with the design, implementation and simulation of novel QCA based Field Programmable Gate Arrays (FPGAs). The research is divided into two phases. In the first phase, Multiplexers, Configurable Logic Blocks, and the Programmable Switch Matrices are designed and simulated. A complete FPGA layout is subsequently presented. In the second phase of the research, the proposed designs are tested for possible QCA faults such as cell displacement, cell misalignment, cell omission, cell rotation and stuck at polarization faults.The proposed QCA designs are compared with earlier research in terms of number of QCA cells, area, and latency. Our proposed CLB design shows an improvement of 24% fewer QCA cells, occupies 62% lesser overall area, and has 53% less latency compared to previous works.The circuits in this research are designed, implemented and simulated using the QCA Designer software tool. 2012-07-09 English text University of Toledo / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=toledo1333730938 http://rave.ohiolink.edu/etdc/view?acc_num=toledo1333730938 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
