Divya Tripathi, Subodh Wairya · Journal of Critical Reviews · 2020
Quantum-dot cellular automata (QCA) is an innovative nanotechnology that grants a good alternative to the silicon technology and offers lesser size, lesser power consumption, with more rapid speeds and deliberated as a clarification to the scaling difficulties with CMOS technology. The loss of points of the CMOS technology is like high power consumption, more power dissipation and speed limitation, those problems will be solved by the QCA technology. In QCA mainly the electrons are going to be moved in- between the quantum dots as per the energy at quantum junctions. The main elements of the QCA design are QCA wire, QCA based inverter, and majority voter gates. In this paper, 4- bit binary to grey and 4- bit grey to binary circuit is proposed and analyzed in terms of area and energy dissipation that takes down the count of QCA cells associated towards the previously reported cell numbers as well as energy dissipation. As XOR gate is base circuit of above code converters so first we designed XOR gate and then we will proposed above code converters. The proposed course of study involves just around 16% of the area as compared to the preceding figure with the lesser speed, clocking performance and energy dissipation. Simulation inquiries and parameter evaluation have been supported by QCA designer E tool. QCA designed circuits have advantages of high speed, high integrity and less power consumption as well as high parallel processing.
