摘要
多值逻辑是计算机科学的一个新分支.本文首次将多值逻辑的概念应用于D/A转换器,提出了通用多值T型电阻解码网络电路形式与计算方法。并由此设计出一种新型的多值D/A转换器。分析和实验证明:多值D/A转换器在灵敏度、转换精度方面优于二值TTLD/A转换器。
Multiple-valued logic is a new branch of computer science. In this paper, concept of multiple-valued used for D/A convertor and a current T type resistor decoding network circuit and its method of calculation is presented for the first time, which is used in multiple- valued D/A convertor. It is shown that multiple - valued D/A convertor is superior to binary TTL D/A convertor in its sensitivity, conversion accuracy and integration level through theoretical analysis and experiments.
