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.
