| 摘 要： | 文中给出一个R－2R电阻网络的新的校正算法。被应用的R－2RT型电阻网络主要是由集成电路实现的，但电阻的公差限制了它的线性。应用校正技术，可以提高其线性度。Cutscky以前曾提出了一种应用于Cutscky R-2R电阻网络的校正算法。据此，可推导出针对电流输出的T型电阻网络的类似的算法。笔者着重介绍了倒T型电阻网络的校正算法。

| Abstract: | This article gives a new calibration algorithm for R-2R T-resistance network. The widely applied R-2R T-resistance network is primarily accomplished by integrated circuit, but its linear degree is limited by the resistance tolerance. To adopt calibration skill can increase its linear degree. Cutscky has ever advanced a calibration algorithm for R-2R resistance network, from which we can infer a similar algorithm for current-output T-resistance network. |
