摘　　要：介绍一种用于有机 聚合物LED微弱电流的自动测量装置。装置将测量参数估计理论与T形负反馈电阻网络相接合以实现高准确度微弱电流自动测量。装置电流测量范围为1fA～100mA;测量准确度为0 1%～10%R;分辨率为1fA;极限灵敏度为0 5fA。测量数据通过标准接口传输,经自动数据处理后,可提供微弱电流各分量频率谱、幅值相位谱以及随机过程的统计参数分析。A new computer-controlled apparatus for weak current measurement of organic/polymer light-emitting diode (LED) is proposed, in which the estimation method of parameters combining with T-type negative feedback resistance network is used to realize, a high accuracy and automatic measurement of the weak current. The current measurement ranges are from 1 fA to 100 mA. The measuring accuracy is 0.1%～10%R. The resolution is 1 fA. The limit sensitivity is 0.5 fA. The measuring data is transmitted through the standard interface. The frequency spectrum, amplitude phase spectrum and the statistic parameter analyze of the stochastic process for each component of the weak current are provided by automatic data processing.
