当前一些文献中介绍的解码网络,其建码量和它所对应的基准电压量之间的比例关系都是固定不变的。本文介绍一种能使建码量和它所对应的电压量之间的比例关系在很大范围内随意选择和调整的解码网络。这不仅使它在设计和使用上都变得十分灵活方便,而且在相同条件下,其转换精度和转换速度都不会下降。用在权电阻网络上还可以提高精度。为了便于区别,把它叫做宏式解码网络。 Some current literature describes the decoding network, the amount of its code and its corresponding reference voltage between the proportion of the relationship between the fixed. This paper presents a decoding network that allows the ratio between the amount of code and the amount of voltage it corresponds to be freely selected and adjusted over a large area. This not only makes it very flexible and convenient in design and use, but also under the same conditions, its conversion accuracy and conversion speed will not decrease. Used in the resistance network can also improve the accuracy. In order to facilitate the difference, call it a macro decoding network.
