Analogue to information converter design using analogue chua circuit for IoT devices

Abstract

IoT devices design faces several challenges like power consumption, security, privacy and more. In this paper a low power, secured and fully analogue design for the analogue information converter (AIC) preprocessing block (or AIC analogue frontend) is proposed to be used for monitoring systems like the IoT devices. The proposed design is based on replacing the traditional digital pseudo random generator like linear feedback shift register (LFSR) by analogue Chua circuit. This replacement overcomes any need of isolation between analogue parts and digital parts of the AIC and add security to the input data. Chua circuit has been presented by 4 different implementations. The different implementations for the Chua circuit have been tested for the performance of reconstructing the original signal and the power consumption. The study is based on simulation using Multisim Pspice, and Matlab software and based on the off the shelf component.
