Digital-to-Analog Converter Architectures Based on Polygonal Numbers

This paper describes new configurations of digital-to-analog converters (DACs) based on number theory, and shows their architecture design in 6-bit case. They consist of N current sources, N-angle number weighted resistor networks, switch arrays and decoders (N= 3, 4, 5,..). Their principles, configurations and operations as well as simulation results are presented. キーワード:デジタルアナログ変換器,多角数, 整数論 (Digital-to-Analog Converter, Polygonal Number, Integer Theory)
