Design of An Integrated Three Dimensional Hybrid Multi-Bit Advanced Combinational Reversible-Circuit Using “Q-C-A”

To get an advanced high dens device the unit-area-occupation of every single used electronic component must be reduced without increasing the circuit delay, device complexity, and dissipated power. Thus a more advanced low power high-speed technical field is required at present compared to widely used transistor-level technologies (mainly “C.MOS technical way”). The “Quantum-dot cellular-automata” or “Q-C-A” nano-technique is preferred in this research to design a highly developed hybrid reversible model of multi-bit Adder-XOR combination in a multilayer 3D platform. An integrated circuit formation based on an arithmetic circuit (Adder) and a logic circuit (XOR-operation) and its advancement representation based on unit required area, delay, power, complexity, and cost are the major achievements of this presented work. 3-input Feynman gate and modified reversible universal gate (M-RUG) are combined in the proposed advanced integrated structure with majority-gate (M-g) to configure the design in a hybrid manner by using the 3D crossing to explore the parametric upgrades of the “Q-C-A” based structures. Additionally, subtraction operation is also presented through the advanced Adder structure by applying reversibility to it. Two types of trade of multilayer 3D structure are discussed in this work also by stability maintenance investigation of proposed design based on temperature tolerance, layer-separation-gap reduction effects, and output-strength-change.
