Outline of Final Research Achievements |
Several circuit/layout algorithms for AD/DA converters have been developed based on number theory, which can improve their performance. These have been verified with theoretical analysis and simulation results. (1) Layout algorithms for segmented DA converters have been developed based on magic squares and Latin squares.(2) Successive approximation register (SAR) ADC architectures with golden ratio weights and silver ratio weights have been investigated and it is shown that they can be reliable, error tolerant and high speed. Also their internal DA converter circuit configurations with simple architectures have been proposed. (3) The relationship between the golden-weighted SAR ADC and the golden ratio search algorithm has been clarified.
