Abstract

The Quantum Dot Cellular Automata (QCA) is an emerging quantum electronics technology in which quantum cells are the fundamental building blocks. In this work, a Binary to Gray (BTG) code converter design is proposed and implemented using the QCA Designer Tool. This code converter design requires fewer cells than earlier designs and also increases the converter’s implementation bit size to five. The primary objective of this proposal is to introduce a BTG code converter design that excels in temperature stability and energy efficiency. The cell count in the proposed converter design for two-bit, three-bit, and four-bit is decreased by 68.55 %, 66.52 %, and 67.77 %, respectively and the overall area improved by 46.15 %, 52.17 %, and 57.58 % for 2- bit,3-bit and 4-bit, respectively by considering a latency of 0.75. The five-bit BTG has an area of 0.20 µm² with a cell count of 141 and a latency of 0.75. To validate the functionality of the proposed design, extensive simulations were carried out using the QCA Designer tool, QCA DesignerE tool, and QCA Pro tool respectively.

设计高能效、低成本的二进制灰码转换器，并进行温度和稳定性分析

量子点蜂窝自动机（QCA）是一种新兴的量子电子技术，其中量子单元是基本的构建模块。在这项工作中，我们提出了一种二进制到灰度（BTG）代码转换器设计，并使用 QCA 设计工具进行了实现。与之前的设计相比，这种代码转换器设计所需的单元更少，同时还将转换器的实现位尺寸增加到了五个。本提案的主要目的是引入一种 BTG 代码转换器设计，该设计在温度稳定性和能效方面表现出色。考虑到 0.75 的延迟，所提出的转换器设计中，2 位、3 位和 4 位的单元数分别减少了 68.55%、66.52% 和 67.77%，2 位、3 位和 4 位的整体面积分别增加了 46.15%、52.17% 和 57.58%。五位 BTG 的面积为 0.20 µm2，单元数为 141，延迟为 0.75。为了验证拟议设计的功能，我们分别使用 QCA Designer 工具、QCA DesignerE 工具和 QCA Pro 工具进行了大量仿真。
