Outline of Research at the Start

IoT機器の普及とその応用技術の発展が期待されている中,ワイヤレス・センサを用いる情報取集システムでは,通信経路およびIoT機器の情報保護技術が重要となっている.電子回路による自動暗号化の実現を目指しているハードウェアセキュリティ技術の開発では,ベータ展開の数理理論に基づくアナログ・デジタル変換(AD変換)方式,小型AD変換回路実現手法とデジタル信号処理技術を融合したセキュアなAD変換器回路を開発する.具体的には,簡単なアナログ回路で実現可能な小型AD変換器回路を取り上げ,ソフトウェア親和性の高い非2 進AD変換手法を活用する新規のセキュアなAD変換技術を開発する.

Outline of Final Research Achievements

In this study, we developed a design technique for low-voltage non-binary analog-to-digital converters (ADCs). We developed low-voltage techniques for each analog element circuit integrated in the low-voltage ADC and successfully demonstrated the feasibility of the developed low-voltage circuitry through experimental verification. We established a noise analysis method, which is a technical challenge in low-voltage cyclic ADC design, and validated the validity of this noise analysis method through experimental verification. Furthermore, we established a system design methodology for ADCs that includes the aforementioned element techniques and confirmed the feasibility of low-voltage, high-precision ADCs based on the proposed approach, as well as the effectiveness of the proposed methodology through the results of experimental verification.

Academic Significance and Societal Importance of the Research Achievements
