Analog buffer amplifier using reconfigurable FET and gate-all around FET devices are demonstrated to analyze the feasibility of using multi-gate device in analog circuits. In this paper, a unity gain OTA buffer and a simple configuration for a variable gain OTA buffer amplifier are presented. The gain can be varied without changing any other circuit parameters, thus making the configuration more flexible compared to the existing buffer amplifier designs.

In the case of Taiwan Semiconductor Manufacturing Company (TSMC) who was forced to shut down several factories after revealing is being attacked by a malware in August 2018. The incident caused attention on the security of smart manufacturing industry whilst in the past, management issue of cybersecurity for Operational Technology (OT) were rarely discussed. As such if we are unable to provide good defense for information security among sensor networks and OT environment, the development of smart application system and industry 4.0 will be potentially precarious.
